摘要：
In this paper, unique structure of an optical add-drop multiplexer (OADM) based on bidirectional Fiber Bragg Grating-Optical circulator (FBG-OC) has been investigated for dense wavelength division multiplexed system with different modulators like Amplitude Modulator (AM), Mach-Zehnder (MZ) and Electro absorption (EA). This investigation has been done at 40 Gbps/channel with ultra-narrow channel spacing of 0.1 nm. Using AM modulator, the maximum distance can be achieved over 70 Km with acceptable BER performance. It is reduced to 50 and 30 Km with MZ and EA respectively. In addition, it is also observed that the structure provides acceptable BER performance with maximum FBG bandwidth of 280 GHz and insertion loss of 9 dB, circulator insertion loss of 4.5 dB for Amplitude Modulator.
