tìm hiểu về Sợi quang viễn thông, mạng viễn thông | Fundamentals of Photonics Module Fiber Optic Telecommunication Nick Massa Springfield Technical Community College Springfield Massachusetts Fiber optics is a major building block in the telecommunication infrastructure. Its high bandwidth capabilities and low attenuation characteristics make it ideal for gigabit transmission and beyond. In this module you will be introduced to the building blocks that make up a fiber optic communication system. You will learn about the different types of fiber and their applications light sources and detectors couplers splitters wavelength-division multiplexers and state-of-the-art devices used in the latest high-bandwidth communication systems. Attention will also be given to system performance criteria such as power and rise-time budgets. Prerequisites Before you work through this module you should have completed Module 1-7 Basic Principles of Fiber Optics. In addition you should be able to manipulate and use algebraic formulas deal with units and use basic trigonometric functions such as sine cosine and tangent. A basic understanding of wavelength frequency and the velocity of light is also assumed. 2000 University of Connecticut 293 Fundamentals of Photonics Objectives When you finish this module you will be able to Identify the basic components of a fiber optic communication system Discuss light propagation in an optical fiber Identify the various types of optical fibers Determine the dispersion characteristics for the various types of optical fibersDescribe the various connector types Calculate decibel and dBm power Calculate the power budget for a fiber optic system Calculate the bandwidth of a fiber optic system Describe the operation and applications of the various types of fiber optic couplers Describe the operation and applications of light-emitting diodes LEDs Describe the operation and applications of laser diodes LDs Describe the operation and applications of distributed-feedback DFB lasers Discuss the differences
