Fujitsu Network Communications announced today the general availability of second-generation 40 Gbps interfaces for its FLASHWAVE 7500 ROADM. Utilizing an adaptive differential phase shift keying (ADPSK) modulation scheme and Fujitsu patented Variable Dispersion Compensation (VDC), the second generation units are intended to enable network growth up to 1.6 Tbps of capacity.

Three new 40 Gbps units are now available for the FLASHWAVE 7500 ROADM, including the 40 Gbps Transponder, 4:1 Muxponder, and 40 Gbps Regenerator. Primarily intended for 40 Gbps core router interconnection services, the 40 Gbps Transponder provides a full-band tunable network interface and an OC-768 client interface. Supporting four 10 Gbps client interfaces, the 4:1 Muxponder provides a method for aggregating 10 Gbps traffic and quadrupling the capacity of existing 10 Gbps-based networks. The 40 Gbps Regenerator provides electrical signal regeneration for long spans.

All units support ITU G.709 OTN standards for mapping client signals, optical layer performance monitoring, alarm indication signals, and enhanced forward error correction (EFEC).
