Lona Haul System Issues with Bragg Fiber Grating-Based Dispersion Compensation

摘要

Using an accurate optical system simulation for Bragg fibergrating dispersion compensators, the fundamental limitations onsystem perfor- mance incurred by these devices operating inreflection and transmission, are studied. When the devices areoperating in reflection, the limitation on system performance is dueto group delay and reflectivity ripple. When they are operating intransmission, the limitation on system performance is due todispersion slope of the grating. A range of issues, including theimpact on system performance of ripple period and amplitude,concatenating many gratings, and system bit rate are considered. Theresults show that systems based on WDM with lower channel line ratesare the more resilient to limitations introduced by these devicesthan high-speed TDM systems.
