Impact of Crosstalk in an TFGB OC Based Reconfigurable Optical Add/Drop

Tunable fiber Bragg grating (TFBG) based wavelength division multiplexing (WDM) reconfigurable optical add/drop multiplexer (OADM) will play an important role in WDM optical networks. One possible implementation of the OADM is to use two optical circulators (OCs), a set of tunable fiber gratings and
