摘要：Abstract— Wavelength division multiplexing (WDM) optical networks are attracting more and more attention because of their ability to provide increased capacity and flexibility. Optical add-drop multiplexer (OADM) becomes a key component to add or drop wavelengths in high bit rate optical networks. Crosstalk in OADM often degrades the performance of WDM system drastically. In this article, we have developed analytical model for low crosstalk of fiber Bragg grating based OADM with isolator. We have also derived analytical expressions for relative intensity noise (RIN), bit error rate (BER) and power penalty to evaluate the performance limitations of this OADM. Results show that crosstalk, RIN and BER of the proposed OADM are significantly lower and provide better performance than the existing OADMs.
