Fiber Optic Communication Systems Training
Fiber Optic Communication Systems Training Course Description
This three-day Fiber Optic Communication Systems Training investigates the basic aspects of digital and analog fiber-optic communication systems. Topics include sources and receivers, optical fibers and their propagation characteristics, and optical fiber systems. The principles of operation and properties of optoelectronic components, as well as signal guiding characteristics of glass fibers are discussed. System design issues include both analog and digital point-to-point optical links and fiber-optic networks.
• What are the basic elements in analog and digital fiber optic communication systems including fiber-optic components and basic coding schemes?
• How fiber properties such as loss, dispersion and non-linearity impact system performance.
• How systems are compensated for loss, dispersion and non-linearity.
• How a fiber-optic amplifier works and it’s impact on system performance.
• How to maximize fiber bandwidth through wavelength division multiplexing.
• How is the fiber-optic link budget calculated?
• What are typical characteristics of real fiber-optic systems including CATV, gigabit Ethernet, POF data links, RF-antenna remoting systems, long-haul telecommunication links.
• How to perform cost analysis and system design? From this course you will obtain the knowledge needed to perform basic fiber-optic communication systems engineering calculations, identify system tradeoffs, and apply this knowledge to modern fiber optic systems. This will enable you to evaluate real systems, communicate effectively with colleagues, and understand the most recent literature in the field of fiber-optic communications.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
