Optical Communication Systems

Prior Learning Assessment Learning Narrative OPTI 430 Optical Communication Systems

The fourth upper level college course that I will apply my learning experiences to are the expected learning outcomes form the University of Arizona, Optical Communication Systems. The optical communication systems revolution started when researchers at Corning Glass Works in Corning, NY, invented fiber optic technology in 1970.

<标题> Over the decades, the quality and design of optical fiber has improved immensely, and, in 1977, the first fiber optic network was built and tested (Sterling, 2004, p. 6). Today, the World’s economic system is dependent upon its ability to communicate and transmit voice, video, and data information.

Networks of optical fiber, coupled with millions of fiber optic connectors, span continents and circle the globe making this communciation possible. The rapid expansion in use of the Internet drives the broader optical market. Optical networks transmit voice, video, and data across the country and around the world.

<标题> My humble experience in optical communication systems has shown me that fiber optics technology is a wonder to behold. I understand and teach my students daily that when the transmitter sends a signal through a whisker-thin optical fiber, the signal is carried on a beam of light that travels in waves.

The number of waves that leave the transmitter per second is the frequency. The higher the frequency, the more information is carried. Since light waves have such a high frequency, fiber optic cable can carry thousands of times more information than current flowing through a copper wire.

I understand that a fiber optic cable the size of an ordinary electrical cord can replace a copper cable hundreds of times thicker. I learned early in my optoelectronics and fiber optics career that copper cables are susceptible to static, which interferes with communication.

Because optical fibers carry light beams, they are free of electrical noise and electromagnetic interference (EMI). Recent breakthoughs in fiber technology, such as wavelength division mulitiplexing (WDM) and optical amplifiers, have made transmission of an incredible amount of information across a single strand of fiber optic cable possible.

In 1995, Nicolas Negroponte wrote in Being Digital:

<标题> We don’t know how many bits per second we can send down a fiber. Recent research says we’re close to being able to deliver 1,000 billion bits per second. This means a fiber the size of a human hair can deliver every issue ever printed of the Wall Street Journal in less than a second (Johnson, 1998, ¶8).

<标题> A year later, a trillion bits per second were successfully transmitted, error free.

I just recently attended a webinar titled “The "40GE and 100GE: Ready for Prime Time?” presented by Telecommunications Online and Infonetics Research, and sponsored by JDSU, Mintera, and Nokia Siemens Networks. The basic driver behind the growth to 40 Gigabit Ethernet and 100 Gigabit Ethernet is the traffic keeps growing and the future traffic will be crushing. More use and new services are driving demand, video is becoming a major bandwidth driver, high capacity storage area network (SAN) requirements are exploding, and 40G router interfaces are driving OC-768 (40 Gigabit) capability.

<标题> I learned during this webinar that in order for us to effectively upgrade systems to 40 Gb/s and 100 Gb/s that we first must address the transport and transmission issues. There are 40G systems already deployed and in use today. They support 80 x 40G in the C band of the electromagnetic spectrum.

They can transparently reach to lengths greater than 1500 kilometers; have a high tolerance to Chromatic Dispersion (CMD) and an increased tolerance to Polarization Mode Dispersion (PMD). Both 40G-only and mix of 10G/40G links are currently deployed in networks of major carriers in North America and Europe. Who knows what the future holds?

Most people in the fiber optics industry have their eye on the business community’s and homeowner’s demand for high-speed local area networks (LANs) consiting of fiber optic cable, connectors and related products. This end of the market is ready to explode, say many industry observers, now that fiber has made the move from being a primarily backbone cable for large networks to now linking directly to the home in Verizon’s Fiber Optic System (FiOS) technology.

The fiber to the home and desktop is driven by the requirement of PC software applications for more bandwidth on the cabling media that carry information (i.e. voice, video and data) to the home and businesses.

<标题> I started my career in fiber optics while I was still active duty in the Navy (Document 4). This was 1993, which was a new and exciting time to be studying and learning optical communication systems in the military. The Navy was just beginning to convert over their legacy copper networks and upgrading them to fiber optic communication network designs. My career in fiber optics technology actually started when I was assigned as a 3M (Materials, Management, and Maintenance) Systems Coordinator, Fiber Optic LAN Administrator onboard USS Briscoe (DD-977), Norfolk, VA (Document 5, Document 1).

While on the Briscoe, I received specialized advanced training in Unix Systems Administration, Novell Systems Administration, and Fiber Optics technology. I was very lucky to be “chosen” for this training, because at the time there were only a few schools specializing in optical communication systems. After this formal training, I assumed and eagerly took on the additional role as Briscoe's Fiber Optics Computer Network Systems Administrator (Document 2).

This is where I first was introduced to the truly exciting profession of fiber optics communication systems technology. This tour of duty was where I started to concentrate my interests in the area of optoelectronics, optical fiber, transmitters, receivers, amplifiers, and active and passive optical components.

<标题> My career plan after retiring from the Navy was to change jobs not too often, but not to stay very long at any one company. I had just spent the last 22 years with the same company and my goal was to learn new things, contribute enough, and then after three or four years, move to the next level at a new company. This all changed though while I was attending ECPI College of Technology during my last Navy active duty tour.

During the evenings for the next two years, I attended ECPI and finally reached my first education goal, achieving an Associates of Applied Science degree in Computer Electronics Engineering Technology. While attending ECPI, I took several electronics and optics courses including Electricity Fundamentals, Electronics Technology I, Electronics Technology II, Digital Technology I, Digital Technology II, and Fiber Optic Communication (Document 6).

<标题> This only proved to spark my interest even more in fiber optics technology. So early in my optics career I attended two more industry fiber optics certification courses and earned my Electronics Technicians Association, International fiber optics industry certifications as a Certified Fiber Optics Installer and Certified Fiber Optics Technician (Document 7, Document 8).

<标题> In the Certified Fiber Optics Installer course, I was introduced to fiber optics and established a thorough understanding of the fiber optics industry and its technology, common terminology, fiber optic theory, and photonic components. In addition, I learned to assemble fiber optic connectors using standard commercial-off-the-shelf (COTS) connectors, test fiber optic connectors, splices, and cables in accordance with telecommunication industry standards.

<标题> Finally, I learned to build and test fiber cables and photonic components using standard mechanical splices and learn appropriate techniques for fusion splicing and testing fiber optic cables with both an Optical Loss Test Set (OLTS) and an Optical Time Domain Reflectometer (OTDR).

I understood early in my career in optical communications that I must continue to build on my solid foundation in fiber optic theory. In the Certified Fiber Optics Technician course, I learned in detail fiber optic cable technology. It examined more in-depth the electronics technology built into fiber optic transmitters, receivers, and test equipment.

In addition, I learned how to test and troubleshoot a fiber optic link to the current industry standards. These industry certifications demonstrate to my employer that I have the knowledge and hands-on skills required to install, test, and troubleshoot fiber optic links and systems.

While attending ECPI College of Technology, I met some of the lead technical faculty at the college, and they showed an interest in hiring me to teach part-time electronic and fiber optics technology courses in the evenings at the college, once I graduated from ECPI. As a result, while I was still on active duty, I started teaching both electronic and fiber optics technology courses for ECPI College of Technology.

Once I completed my active duty tour and retired from the Navy, ECPI College hired me on as a full time Technical Faculty member. So as a result, I began a very exciting and promising career as an educator and fiber optics training specialist for ECPI College of Technology and our subsidiary corporate and military training company Infotec (Document 27).

<标题> I had been working at ECPI College of Technology for two years and was very happy, when out of the blue my bosses called to speak with me about a promotion. Turns out that ECPI was looking to expand their fiber optics programs (Document 26) and they asked me to become the Lead Technical Faculty and Coordinator of Fiber Optics programs for all of ECPI Colleges.

No one had ever been given this position before at the college, but I felt that I could handle this position with my past expertise and knowledge in the optical communication systems. So I spent a couple of days thinking, doing a little bit of brainstorming, then met with my Department Head and told him I was confident that I not only could expand ECPI’s fiber optics communications programs, but that I could expand it to our other campuses and start a nationally recognized Electronics Technicians Association, International (ETA-I) training program in fiber optics installation and technician (Document 25).

<标题> I knew that if I was going to pull this off that I would need more in depth fiber optics experience, so I requested to attend several optical industry courses of instruction to strengthen my optical communication systems knowledge.

One of the first courses that I attended was called “Fiber Optic Design Course for Multimode and Single-mode Networks” (Document 15). This optical design course targets optical engineers who desire an in-depth knowledge of optical local area networks. The intensive course was written and taught by experience Corning system engineers who work with consultants and end-users daily and meet their optical network requirements.

This course covered all aspects of successful fiber optic system design from the network protocols, network configurations, optical cabling, industry communication standards, determination of fiber count, hardware selection including optical sources whether laser or LED, advanced splicing/termination methods, and cable system testing and documentation. All that I learned was put into practice through multiple and intensive case studies (Corning Cable Systems, 2005).

<标题> While I was at this optical engineering course I was generously given permission from our college President to open a constructive dialogue with the engineers and training department at Corning. What I wanted to do is form a training partnership with Corning, so that I could take all that I learned back with me to ECPI and develop a fiber optic design college course of instruction.

Corning granted ECPI permission to use their course materials (of course for a price), so that I could modify and use in the educational course that I would develop for ECPI. I went back to the college and applying what I learned, I developed our Certified Fiber Optics Designer course (Document 22).

<标题> I then took this particular course development to the next level and asked the Electronics Technicians Association, International if I could develop an industry fiber optics certification for fiber optic designers. I spent the next year developing the knowledge and practical skills learning objectives, and authoring the very first ETA Certified Fiber Optics Designer examination (Document 28).

<标题> I piloted the very first nationally and fiber optics industry certification course with Verizon Telecommunications Technicians as my first students, in my fiber optics laboratory in Virginia Beach. I was the very first ETA Certified Fiber Optics Designer (Document 9) in the country.

<标题> I learned a great deal from the “Fiber Optic Design Course for Multimode and Single-mode Networks” course. As part of this course, I had to learn how to design an optical communication system from the ground up. I learned how important the fiber selection is in the design and how wave propagation, chromatic dispersion, polarization mode dispersion, and both linear and non-linear fiber losses effect your final decision in the design.

<标题> As a designer of optical communcation systems I understand the important role the optical transmitters, optical receivers, and optical amplifiers play in the design. Furthermore, as part of the course we had to calculate a power budget (Corning Cable Systems, 2005). A power budget as defined in IEEE Standard 802.3 is the minimum optical power available to overcome the sum of attenuation plus power penalties of the optical path between transmitter and receiver.

I quickly learned bit-error rate calculations in order to effectively calculate a power budget for both a multimode fiber optic link and a single-mode fiber optic link design. Finally, I learned about the different optical network topology designs including Ethernet, Fiber Distribution Data Interface (FDDI), Synchrounous Optical Network (SONET), Asynchronous Transfer Mode (ATM) and Fibre Channel, and the specific design guidelines involved with these optical communication systems (Document 33).

Previously, optical fiber networks were designed to satisfy specific application(s) requirements, either data, voice, or video. Today, the true benefits of optical fiber are being realized and used to design optical communication systems independent of specific applications. One of the most important topics I learned in this course is the importance of learning and understanding the Telecommunication Industry Association (TIA)/Electronics Industry Alliance (EIA), Institute of Electrical and Electronics Engineers (IEEE), and Telecordia standards.

These telecommunication cabling systems standards were developed to define standards for both copper and optical communication systems. I have since read, studied, and learned several substantial TIA/EIA, IEEE, and Telecordia industry standards and incorporated this knowledge into my fiber optic communication courses (Document 29).

The successful deployment of information technology is critical to the success of most optical communication systems. The need to access and share information is fueling a new level of demand for applications like the internet and intranet and client/server implementations. In turn, I learned that this is driving the need for greater bandwidth, or network speed, to new levels in the backbone and ever closer to the work area and now into our homes with Verizon Fiber Optics System (FiOS).

As the data rates of networking continue to escalate, the use of optical communication systems is becoming even more widespread. I am very busy these days training many contractors, military, and end-users that are now only beginning to deploy fiber for the first time. Others that I have trained are upgrading their legacy copper systems with optical fiber to enhance system bandwidth capability, system performance and/or extending the reach of existing installations.

One of the most challenging series of decisions a telecommunications manager makes is the proper desing of an optical communication system. Optical fiber cable, which has extremely high bandwidth, is a powerful telecommunications media that supports voice, data, video and other applications. However, the effectiveness of the media is greatly diminished if proper connectivity, which allows for flexibility, manageability, and versatility of the cable plant, is not designed into the system.

As the Lead Technical Faculty and Coordinator of Fiber Optics Programs for ECPI College of Technology and Infotec (Document 1), I understand that new technologies, new applications and the need for in-depth product knowledge challenge us to continually enhance our training capabilities. Along those lines I felt it necessary to further strengthen my experiential learning knowledge on the latest optical communication systems.

In 2002, I attended the Sumitomo Electric Lightwave FutureFLEXÒ System Network Standards certification course at Research Triangle Park, NC covering the design, engineering, installation, and administration of the FutureFLEX Air-Blown FiberÒ Optic Cabling System (Document 13). FutureFLEXÒ Air-Blown Fiber (ABF) is a cabling system that transports fiber optic bundles through pre-installed tubes using air or dry nitrogen.

This ground breaking technology was developed by British Telecom in 1982. In 1987, a license was granted to Sumitomo by British Telecom, and in 1990 FutureFLEX was introduced in the United States (“FutureFLEX”, n.d.).

I have included the theory and knowledge of this cabling system into my Military Fiber Optics Installation Professional course (Document 23) that I developed in order to meet the Department of Defense Military Standards Practice for fiber optics installation guidelines. Air Blown Fiber technology delivers the mission critical reliability, security, and rapid distaster recovery necessary for all military applications.

I teach my students about how this cabling system can be utilized in a variety of applications including data communications, LAN and WAN networks, CCTV, Voice communications and more. This technology has a long and distinguished record of serving all branches of the military including its wide adoption as the premier fiber optic LAN backbone solution for naval shipboard applications.

<标题> I am a very passionate person about fiber optics communication technology, which is a major plus for attracting new fiber business opportunities for both the college and Infotec. Teaching at both ECPI and Infotec has been a wonderful opportunity for me personally and professionally. Both companies are not afraid to allow their employees to continue to attend, study, and learn about the latest and greatest technology, so that we can incorporate this learned knowledge and skills into our curriculum development.

<标题> I enjoy interacting with people; as the Lead Technical Faculty and Coordinator of Fiber Optics programs it has given me the opportunity to meet many different optics industry personnel from all over the world. I am very pleased about the fiber optics courses that I have personally developed, co-authored and teach, including Certifed Fiber Optics Installer, Certified Fiber Optics Technician, Certified Fiber Optics Designer, Military Fiber Optics Installation Professional, and Data Cabling Installer Certification (Document 16, Document 17, Document 18, Document 10).

<标题> I continue to expand both mine and my students knowledge in the optics arena by co-authoring the development our newest fiber optics program called Aerospace Fiber Optics Fabricator (Document 30). This training course focuses on proven training practices to meet the aerospace industries Society of Automobile Engineers International (SAE) and Aeronautical Radio Incorporated (ARINC) highest standards of training applicable to aerospace professionals engaged in aerospace fiber optic design, manufacturing, installation, maintenance, and repair for the air transport industry.

<标题> Furthermore, to show that I have continued to learn and expand my fiber optics knowledge, I became a member of the Electronics Technician Association in 1999 (Document 2) and volunteered to serve on the ETA's fiber optics examination committee. As a member and through my work on this committee, I assisted in the initial development and revision of knowledge and hands-on training competencies for the ETA’s Certified Fiber Optics Installer (FOI), Certified Fiber Optics Technician (FOT), Certified Fiber Optics Designer (FOD), and Data Cabling Installer Certification (DCIC) programs. In addition, I have authored several ETA certification examination questions.

<标题> These questions are based on the certification programs knowledge competencies and approved by an international committee of subject matter experts, which I am a member of (Document 28). Besides being an ETA Fiber Optics Examination Committee member, this past year I became a member of SPIE – The International Society of Optical Engineering (Document 3).

<标题> I tell my students everyday that if you are considering going into academia, teaching optical communications may be one of the most rewarding activities you will encounter. I have learned to enjoy it, to value the interaction with those I teach, to continue to keep learning from both industry professionals and from my students, and to be thankful about this great opportunity to be of service to my commununity.

I truly believe that I have proven that my current experiential learning background is that of a typical senior-level or graduate level optical communication systems student. Based on the experiences and knowledge, I've gained through my last 30 years in electronics and optics, I am respectfully requesting three semester hours of OPTI 430 Optical Communication Systems term credit from The University of Arizona.

光通信系統
之前學習評估學習敘事OPTI 430光通信系統
第四上層的大學課程,我將用我的學習經驗,預期的學習成果形成亞利桑那大學,光通信系統。光通信系統的革命開始了,當研究人員在紐約州康寧,康寧玻璃工程,在1970年發明光纖技術。
幾十年來,極大地提高了光纖的質量和設計,并于1977年,第一個光纖網絡構建和測試(英鎊, 2004年,第6頁) 。今天,世界經濟體系是依賴于它的溝通能力和傳輸語音,視頻和數據信息。
網絡的光纖,光纖連接器,跨大洲,盡可能使這個communciation圈全球數以百萬計的耦合。在利用因特網的迅速擴張驅動的更廣泛的眼鏡市場。光網絡傳輸語音,視頻和數據,在全國各地和世界各地。
我謙卑的光通信系統中的經驗已經表明我說,光纖技術是一個奇跡脫俗。我明白了,每天教我的學生,當發射器發送信號通過晶須薄的光纖,信號波傳播的光的光束進行。
離開發射器每秒的波的數目是頻率。的頻率越高,越多的信息進行。由于光波有如此高的頻率,光纖電纜可以攜帶幾千倍以上信息比銅導線的電流流經。
據我所知,光纖電纜的普通電線的大小,可以取代銅電纜數百次較厚。我學會了在我的光電子和光纖事業的早期,銅電纜易受靜電,通信干擾。
由于光纖進行光束,它們都是免費的電氣噪聲和電磁??干擾(EMI) 。最近breakthoughs ,如波分復用mulitiplexing ( WDM )和光放大器,光纖技術已經取得了令人難以置信的大量信息的傳輸光纜可能在一個單鏈。
1995年,尼古拉斯·內格羅蓬特在數字化生存中寫道:
我們不知道有多少位,每秒可以發送了光纖。最近的研究說,我們能夠提供每秒1000億比特。這意味著纖維的大小只有人類頭發永遠印在華爾街日報的每一個問題,可以提供小于第二(約翰遜, 1998年, 8) ¶ 。
一年之后,一兆比特每秒成功發送,無差錯。
我只是最近參加了一個網絡研討會,題為“ 40GE和100GE :黃金時間做好準備?”電信在線和Infonetics研究,并贊助JDSU , Mintera公司和諾基亞西門子通信公司的基本增長背后的驅動??程序到40千兆以太網和100千兆以太網的流量不斷增加,未來的交通將被粉碎。使用和新服務的需求正推動,視頻正在成為一個主要的帶寬驅動器,高容量的存儲區域網絡( SAN )的要求爆炸, 40G路由器接口驅動OC-768 ( 40千兆位)的能力。
我在這個網絡研討會上了解到,為了讓我們有效地提升系統的40 Gb / s和100 Gb / s的,我們必須首先解決交通和傳輸問題。 40G系統已經部署在今天使用。他們支持80× 40G在C波段的電磁頻譜。
他們可以透明地到達長度超過1500公里,有很高的耐色散( CMD )和偏振模色散( PMD )的耐受性增加。只有40G-和組合的10G/40G鏈接的目前在北美和歐洲的主要運營商的網絡部署。誰知道將來會怎樣?
光纖行業中的大多數人有自己的眼睛,商界和房主的高速局域網(LAN)的光纜,連接器及相關產品consiting需求。這個高端市場是隨時會爆炸,許多行業觀察家說,現在光纖已經作出的舉動從主要為大型網絡的主干電纜直接連接到Verizon的FiOS的光纖系統( )技術的家中。
驅動光纖到家庭和桌面PC的應用軟件的要求更多的帶寬布線介質攜帶的信息(即語音,視頻和數據)的家庭和企業。
光纖,而我仍然在海軍現役( 4號??文件) ,我開始了我的職業生涯。這是1993年,這是一個新的和激動人心的時刻在軍事光通信系統的研究和學習。海軍才剛剛開始轉換傳統銅線網絡升級到光纖通信網絡設計。我的職業生涯中光纖技術實際上開始時,我被分配為3M (材料,管理與維護)系統協調員,光纖局域網管理員板載USS布里斯科( DD -977 ) ,諾福克,弗吉尼亞州( 5號文件,文獻1) 。
雖然在布里斯科,我收到了Novell的系統管理, UNIX系統管理和光纖技術的專業高級培訓。 “選擇”這個培訓我很幸運,因為在當時只有少數學校專業光通信系統中。在此之后正式的訓練,我假設,并急切地采取額外的作用布里斯科光纖計算機網絡系統管理員(文獻2) 。
這是我第一次被引入到光纖通信系統技術真正令人興奮的職業。這次巡演的責任是我開始的地方,我在光電領域的利益,光纖,發射器,接收器,放大器,有源和無源光學元件集中。
從海軍退役后,我的職業生涯規劃是不要過于頻繁地更換工作,而不是在任何一個公司呆很長時間。我剛剛度過了過去22年在同一家公司,我的目標是學習新的東西,足夠的貢獻,三年或四年后,移動到一個新的水平在一個新的公司。這一切都變了,雖然我參加ECPI技術學院在我的最后一個海軍現役旅游。
在未來兩年到了晚上,我出席ECPI ,終于達成了我的第一個教育目標,實現應用科學學士學位,在計算機電子工程技術的聯營公司。出席ECPI時,我拿了幾個電子和光學課程,包括電力基礎知識,數碼科技,數碼科技,電子科技II電子科技我我, II ,和光纖通信(文件6 ) 。
這只能證明,激發了我的興趣更是在光纖技術。所以早期我的光學生涯中,我參加了兩個行業光纖認證課程,并贏得了我的電子技術員協會,國際光纖行業認證作為認證的光纖安裝和會計師光纖技術員( 7號文件,文件8) 。
在認證的光纖安裝過程中,我被介紹到光纖,并建立了一個透徹的了解光纖行業和技術,共同的術語,光纖理論,和光子元件。此外,我學會了組裝光纖連接器使用標準的商業現成的現成(COTS)的連接器,測試光纖連接器,接頭,電纜,按照電信行業標準。
最后,我學會了構建和測試光纖電纜和光子元件采用標準的機械接頭和學習適當的方法,熔接和測試光損耗測試儀( OLTS )和光時域反射儀(OTDR )光纖電纜。
我理解光通信早在我的職業生涯中,我要繼續在光纖理論建立在堅實的基礎。認證光纖技術員課程,我學會了詳細光纜技術。研究更深入的光纖發射器,接收器和測試設備中內置的電子技術。
此外,我學會了如何測試和解決目前行業標準的光纖鏈路。這些行業認證,證明給我的老板,我的知識和動手能力光纖鏈路和系統安裝,測試,并解決所需。
出席ECPI技術學院,我遇到了一些領先的技術教師在大學,他們表現出的興趣雇用我教兼職,電子和光纖技術在晚上在大學的課程,有一次我畢業于ECPI 。因此,當我還在現役,我開始教電子和光纖技術ECPI科技學院的課程。
一旦我完成了我的現役之旅,從海軍退役, ECPI學院聘請我作為一個全職技術學院成員。因此,作為一個結果,我開始了一個非常令人興奮和有前途的事業,作為一個教育工作者和光纖ECPI技術學院和我們的附屬公司和軍事訓練公司INFOTEC ( 27號文件)的培訓專家。
我已經工作兩年ECPI技術學院,感到非常高興,當我的老板叫出來的藍色同我講,關于推廣的。 ECPI希望擴大自己的光纖計劃“ ( 26號文件) ,他們問我要成為ECPI學院所有的光纖方案技術學院牽頭和協調。
從來沒有人得到這個位置,之前在大學,但我覺得我能勝任這個位置在光通信系統與我過去的專長和知識。所以我花了幾天思考,做一個小一點的頭腦風暴,然后遇見我的部門主管,告訴他我有信心,我不僅可以擴大ECPI的光纖光學通信程序,但我可以擴大它向我們的其他校園并啟動一個全國公認的電子技術員協會,國際( ETA -I )光纖安裝和技術人員的培訓計劃( 25號文件) 。
我知道,如果我打算退出這個功能,我需要更深入光纖體驗,所以我要求參加一些眼鏡行業的指導課程,以加強我的光通信系統知識。
我參加的第一個課程之一被稱為“光纖設計多模和單模網絡課程” ( 15號文件) 。這種光學設計課程目標,光學工程師,誰的愿望光學局域網絡的深入了解。密集課程,編寫和教授的經驗康寧系統工程師,顧問和最終用戶的日常工作,并滿足他們的光網絡要求。
本課程涵蓋從網絡協議,網絡配置,光纖電纜,行業通信標準,測定纖維計數,硬件選擇,包括激光或LED ,先進的拼接/終止方法,和電纜系統的光源是否成功的光纖系統設計的各個方面測試和文檔。付諸實踐,我學會了通過多個密集的案例研究(康寧光纜系統,2005年) 。
雖然我是在這個光學工程課程,我慷慨地給我們的大學校長的許可,開啟一個建設性的對話與工程師和培訓部門在康寧。我想要做的是什么形成了培訓與康寧的合作,這樣我就可以采取一切跟我回去,我學會了ECPI和發展的光纖設計大學課程教學。
康寧授予ECPI許可使用其課程教材(當然價格) ,這樣我就可以在教育的過程中,我會開發ECPI修改和使用。我又回到了大學,并運用我學到了什么,我開發了我們的認證的光纖設計課程( 22號文件) 。
然后,我把這個特殊的課程發展到一個新的水平,并要求電子技術員協會,國際的,如果我能開發一個工業光纖光纖設計師認證。我花了明年發展的知識和實際技能的學習目標,并創作第一ETA認證光纖設計審查( 28號文件) 。
我駕駛的全國第一和光纖光學行業認證課程與Verizon電信技術員作為我的第一個學生,我的光纖光學實驗室在弗吉尼亞海灘。我是第一ETA認證光纖設計師( 9號文件) ,在該國。
我學到了很多,從“光纖多模和單模網絡”課程設計課程。作為本課程的一部分,我不得不學習如何設計從地上爬起來的光通信系統。我學會了在設計和波的傳播,色散,偏振模色散,線性和非線性光纖虧損如何影響你的最終決定設計纖維的選擇是多么的重要。
作為光通信電子系統的設計師,我明白光發射機,光接收機,光放大器在設計中發揮的重要作用。此外,作為課程的一部分,我們不得不計算功率預算(康寧光纜系統,2005年) 。 IEEE 802.3標準中定義的功率預算是最低的光功率可克服發射器和接收器之間的光路衰減,加上電源處罰的總和。
我很快就學會了誤碼率計算,以有效地計算出多模光纖鏈路和單模光纖鏈路設計的功率預算。最后,我學到了不同的光網絡的拓撲結構設計,包括以太網,光纖分布數據接口(FDDI) , Synchrounous光網絡( SONET ) ,異步傳輸模式(ATM)和光纖通道,以及參與這些光通信系統的具體設計指引(文獻33 ) 。
此前,光纖網絡的設計,以滿足特定的應用程序( S)的要求,無論是數據,語音或視頻。今天,實現光纖的真正好處,并用于設計光通信系統中,獨立于特定的應用程序。在這個過程中我學到的最重要的議題之一是電信工業協會(TIA) /電子工業聯盟( EIA ) ,電氣和電子工程師學會( IEEE ) , Telecordia公司標準的學習和理解的重要性。
這些電信布線系統的標準來定義標準的銅纜和光纖通信系統。因為我已經閱讀,研究,并學到了一些實質性的TIA / EIA ,IEEE和Telecordia公司行業標準,并納入到我的光纖通信課程( 29號文件) ,這方面的知識。
信息技術的成功部署,大多數光通信系統的成功是至關重要的。訪問和共享信息的需要刺激需求的應用,如Internet和Intranet和客戶機/服務器實現一個新的水平。反過來,我了解到,這是駕駛需要更大的帶寬或網絡速度,在骨干到新的水平越來越接近工作區,現在變成我們的家園與Verizon的FiOS光纖系統。
隨著網絡的數據傳輸速率的不斷升級,光通信系統中的使用變得更加普遍。我這幾天很忙許多承包商,軍事培訓和最終用戶,現在才剛剛開始部署光纖的第一次。其他,我已經訓練提升他們的傳統銅系統的光學纖維,以提高系統的帶寬容量,系統性能和/或擴展現有設施的覆蓋范圍。
的最具挑戰性的一系列判決的電信管理器使得德興的光通信系統是適當的。光纖電纜,它具有非常高的帶寬,是一個功能強大的電信媒體,支持語音,數據,視頻和其他應用程序。然而,媒體的有效性大大減弱,如果正確的連接,允許靈活性,可管理性和多功能性的電纜廠,是不是設計到系統中。
作為牽頭技術學院ECPI學院的技術和INFOTEC (文獻1)光纖項目協調員,據我所知,新技術,新應用和深入的產品知識挑戰需要我們不斷提高我們的培訓能力。沿著這些線路,我覺得有必要進一步加強我的體驗學習知識的最新的光通信系統。
2002年,我參加住友電工光波FutureFLEXÒ系統網絡標準認證課程在北卡羅萊納州研究三角園,涵蓋設計,工程設計,安裝,和管理的吹空氣FutureFLEX的FiberÒ光纖布線系統( 13號文件) 。 FutureFLEXÒ空氣吹纖( ABF )是一個綜合布線系統,光纖束傳輸通過預裝管使用空氣或干燥氮氣。
這一突破性的技術是由英國電信于1982年。在1987年,被授予許可證住友由英國電信,并于1990年在美國推出FutureFLEX ( “ FutureFLEX ” ,ND ) 。
我已經包含了這個布線系統的理論和知識,我的軍事光纖安裝專業課程( 23號文件) ,是我公司開發,以滿足國防軍事標準實踐部光纖安裝指引。空氣吹纖技術,提供關鍵任務的可靠性,安全性,和的快速distaster恢復所需的所有軍事上的應用。
我教我的學生如何在各種各樣的應用,包括數據通信,局域網和廣域網,中央電視臺,語音通信,更可以利用這個布線系統。這項技術有一個長期和杰出的服務記錄所有的兵種,包括其最大的光纖局域網主干海軍艦載應用解決方案的廣泛采用。
有關光纖通信技術,這是一個重大的加INFOTEC學院和吸引新的纖維業務的機會,我是一個非常熱情的人。 ECPI INFOTEC教學一直是一個極好的機會,我個人和專業。兩家公司都不怕,讓他們的員工繼續參加,學習,了解最新和最偉大的技術,所以我們可以將學到的知識和技能納入我們的課程開發。
我喜歡與人交往;作為牽頭技術學院和光纖計劃協調員它給了我機會,以滿足來自世界各地的許多不同的光學元件行業的人員。我很高興的光纖課程,我曾親自開發,合作撰寫和教導,包括Certifed光纖安裝,光纖技術員認證,認證的光纖設計,軍用光纖安裝專業和數據布線安裝認證(文件16 ,文件17 ,文件18 ,文件10) 。
我繼續在光學領域,努力擴大我和我的學生的知識共同創作的發展,我們最新的光纖稱為航天光纖加工商( 30號文件)的程序。本次培訓課程的重點是行之有效的培訓方法,以滿足航空航天業的國際汽車工程師學會( SAE )和航空無線電公司( ARINC)最高標準的培訓,適用于航空航天專業從事航空航天光纖設計,制造,安裝,維護,修為航空運輸業的發展。
此外,為了表明我繼續我的光纖知識學習和拓展,我成了電子技術員協會的成員,在1999年( 2號文件) ,并自告奮勇擔任埃塔的光纖審查委員會。作為一個成員,并通過我對這個委員會的工作,我協助的初始開發和修訂的知識和手, ETA的認證光纖光學安裝( FOI ) ,認證光纖光學技術員( FOT ) ,培訓能力認證光纖光學設計師( FOD ) ,和數據綜合布線安裝認證程序( DCIC )的。此外,我還撰寫了幾ETA認證試題。
這些問題都是基于認證計劃的知識能力和學科專家,我( 28號文)的成員由一個國際委員會的批準。除了埃塔光纖考試委員會成員,在過去的一年中,我成為SPIE - 國際光學工程學會(文獻3)中的一員。
我告訴我的學生每天,如果你正在考慮進入學術界,教學光通信可能你會遇到的最有意義的活動之一。我已經學會去享受它,重視互動與那些我教,繼續保持業內專業人士,從我的學生學習,并要感謝這個偉大的機會,我commununity服務。
我真的相信,我已經證明了我目前的體驗式學習的背景,是一個典型的高層或研究生水平的光通信系統的學生。根據我的經驗和知識,我過去30年來在電子和光學已經獲得通過,我恭敬地請求OPTI 430光通信系統的長期信貸從亞利桑那大學的三個學期小時。
