Optical Fiber Communication and Systems By OFC FACULTY ALTTC, Gzb. BSNL OF Comm& s OFC Faculty 2 CONTENTS Optical fiber concept& type Fiber characteristics There are several points in an optic system where losses occur. These are: coupler, splices, connectors and the fiber itself. Light propagated in optical fiber in form of modes. Spatial distributions of EM fields do not change with time. No of Modes? V number (normalized frequency) define number of possible modes for a fiber: V (2aNA) where a is radius of fiber, and is wavelength of light. optical fiber systems pdf Line Coding in Optical Transmission Some fiber systems use the line codes described for wireline transmission that we studied previously. A few line codes are specifically developed for fiber applications. Note that optical sources and detectors are primarily used in nonlinear modes of operation with significant gain and threshold variations.

Fiber optic links require a method to connect the transmitter to the fiber optic cable and the fiber optic cable to the receiver. In general, there are two methods to link optical fibers together. optical fiber systems pdf The security inherent in optical fiber systems is a major benefit. Cable television or community antenna television (CATV) companies also find fiber useful for video services.
