Abstract

ABSTRACTIt is first time to study on Gauss pulse transmission over ultra-high PMD fiber. Gauss pulse isbroken into a series of deformed pulse when it transmits over ultra-high PMD fiber. He has explained that the walk-off deformed pulses cause by ultra-high PMD. Transmitted experiment hasbeen done using fiber with PMD coefficient 237.95ps/km112. The simulated result is consistent withexperiment.

INTRODUCTION The increasing demand for bandwidth is driving most telecommunication operators toward thedeployment of large capacity transmission systems. When chromatic dispersion and loss in opticalfiber no longer limits the data-rate transmission systems, polarization mode dispersion (PMD) couldbecome the key factor to update high-performance optical transmission and networks. In high bitrate optical communication systems beyond 10 Gb/s, signal distortion caused by PMD is a majorlimitation on transmission distance1. PMD is a distortion arising from unwanted birefringence in
