✦ Synopsis

Using an accurate optical system simulation for Bragg fiber grating dispersion compensators, the fundamental limitations on system performance incurred by these devices operating in reflection and transmission, are studied. When the devices are operating in reflection, the limitation on system performance is due to group delay and reflectivity ripple. When they are operating in transmission, the limitation on system performance is due to dispersion slope of the grating. A range of issues, including the impact on system performance of ripple period and amplitude, concatenating many gratings, and system bit rate are considered. The results show that systems based on WDM with lower channel line rates are the more resilient to limitations introduced by these devices than high-speed TDM systems.
