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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
