Abstract

The maximum channel density for digital transmission can be achieved by increase the bit rate. When the bit rate cross the 2.5Gbps , the PMD degrade the transmission characteristics. PMD occurs in single mode fiber and because of PMD it impossible to transmit data reliability at high speed. This effects results the widening the pulses and reduce the capacity of transmission of the fiber. This work analyzes the effect of PMD in optical fiber in one hindered km link fiber. The eye diagram, Q value and bit rate for analyzing the PMD. Also an optical compensation technique by which the effect of PMD can be reduced is also analyzed. bit error rate can be achieved by simulating with OptSim 5.3, which includes the algorithms to guarantee the maximum possible accuracy and correct results.

The effect of PMD in an optical fiber link and an optical compensation technique is analyzed through various eye diagrams by performing parametric run

Summary

Introduction

For high speed communication with high quality Optical fiber communication acts as major role. The copper wire between the core replaced by Optical Fiber Com munication for telecommunication. Ninety percentage of communication linked by Optical Fiber communica tion remaining percentage communicated by some other channels. Optical Fiber Communication used telecommunication field bit internet and Local Area network. The advantage of Optical Fiber Communication is low data loss, amplifier kept between long distance, high data carrying capacity. As number of channel increases, dispersion began to show up as obstacles [1]. PMD effects occur only in single mode fiber the result ing the PMD limit the transmission capacity of fiber.
