A Novel Architecture of N × N Bidirectional Reconfigurable Multiwavelength Optical Cross Connect

A novel architecture of N×N bidirectional-reconfigurable multiwavelength optical cross connect (B-RMOXC) based on tunable Fiber Bragg grating and optical circulator is proposed. B-RMOXC network is one of crucial network element for wavelength routing in dense wavelength division multiplexing system. This paper presents a high speed, power compensated bidirectional optical cross connect and verified the performance of bidirectionality with 0.8-nm channel spacing having bit rate of 10 Gbps at different transmission distances. Optical signal-to-noise ratio of 36.62 dB and 35.55 dB is achieved with acceptable Quality factor of 6.26 and 6.99 respectively for upstream and downstream at 60 km having input transmission power of −12 dBm. It is found that the data can be communicated bidirectionally to a distance of 60 km in the presence of fiber nonlinearities without optical amplifier.

Effect of OPC on Fiber Nonlinearities for Dense Soliton Optical Communication Medium

This review paper scrutinizes the staging of dense wavelength division multiplexing soliton system in return to zero and non-return to zero format. In-line optical phase conjugator (OPC) is used to depreciate the power of four wave mixing (FWM). Destructive interference between both the halves of in-line OPC plummets the FWM power sturdily. This paper concludes with the indication that return-to-zero with OPC gives out better performance with FWM suppression.
