FBG-based reconfigurable bidirectional OXC for 8×10 Gb/s DWDM transmission

• The paper presents a bidirectional high-speed, power-compensated, 3×3 reconfigurable and multiwavelength optical cross-connect (RMB-OXC) for all-optical networks.
• RMB-OXC characteristics and its performance are experimentally verified in a bidirectional 8-channel ×10 Gb/s capacity system.
• The optical signal to noise ratio (OSNR) is achieved of 18.4 dB corresponds to a BER of 5×10−10.
• The channel cross-connect function was demonstrated by incorporating RMB-OXC in an 50 km lightwave system.
• We have observed only ~0.5 dB power penalty in the bidirectional transmission in comparison to the unidirectional transmission.
• The proposed FBG-based RMB-OXC can construct the optical WDM network by providing dynamic routing function and high-channel scalability.

The paper presents a bidirectional high-speed, power-compensated, 3×3 reconfigurable and multiwavelength optical cross-connect (RMB-OXC) for all-optical networks. RMB-OXC characteristics and its performance are experimentally verified in a bidirectional 8-channel×10 Gb/s capacity system. The optical signal to noise ratio (OSNR) is achieved of 18.4 dB corresponds to a BER of 5×10−10. The channel cross-connect function was demonstrated by incorporating RMB-OXC in an 50 km lightwave system. We have observed only ~0.5 dB power penalty in the bidirectional transmission in comparison to the unidirectional transmission. The proposed RMB-OXC has vast potential and it can be utilized in many applications in high-speed wavelength division multiplexed (WDM) networks.
