“…However, such a topology has a poor performance in the reliability and the flexibility of adding or removing network nodes. When using the current network architecture whilst considering the cost of equipment build-up, some researchers have suggested that a mixed tree and ring network architecture may be a reasonable solution [ 8 ]. In a ring-shaped architecture, considering scalability and system reliability is necessary; thus, the optical add/drop multiplexer (OADM) is a good choice [ 9 , 10 , 11 ].…”

A new type of passive single-line bidirectional optical add/drop multiplexer (SBOADM) is proposed and experimentally demonstrated. When the proposed SBOADM is placed as a node of a ring topology optical fiber network, the special routing function of the SBOADM can always drop down the desired downstream signals whether the signals are injected into the SBOADM in either the clockwise (CW) or counterclockwise (CCW) direction and can upload and send back the upstream signals via the reversed optical pathway of the downstream signals. Once fiber link failure occurs in the optical network, the blocked network connections can be recovered immediately by sending out the downstream signals in both the CW and CCW directions of the fiber ring. As in all passive devices, the SBOADM needs no power supply or complicated network management to achieve the bidirectional function. Thus, the proposed device is an optimal solution to enhance the stability and reliability of rapidly developed optical fiber networks.

In this paper, we have designed and presented a simulation analysis of 96 × 40 Gbps CSRZ based DWDM long-haul transmission system under the influence of Kerr non-linearities using hybrid dispersion compensation technique. The proposed system performance is measured at 50 GHz channel spacing in terms of BER, Q-factor and eye-diagram for the varied launched power ranging from −4 dB m to 12 dB m of CW laser array and various transmission distances. We have implemented pre-filtering before multiplexing the modulated data of all the channels and post-filtering after de-multiplexing for avoiding co-channel interference and to suppress the cross-talk. By optimizing the system parameters, the transmission distance of 16,500 km is achieved for BER value of 1.48,875E-14 with corresponding Q-factor value of 7.55,989 at 6 dB m input power. The CSRZ modulated system has shown much robustness against the occurred linear and non-linear degradation factors due to its narrow spectrum.
