Fujitsu Network Communications has made enhancements for its FLASHWAVE 7500 ROADM. The update includes new 19- and 23-inch shelves, a two-degree (2D) ROADM configuration, an in-service upgradeable in-line amplifier (ILA), and a 10gbps Flexponder SONET ADM-on-a-card unit. This new release is available immediately.
In this release, several enhancements have been made to the existing 19-inch FLASHWAVE 7500 small configuration to allow it to support 40-channel access via wavelength selective switching (WSS) technology. New options include a 32-channel FOADM, 32-channel ROADM, 40 channel FOADM, or 40-channel WSS-based ROADM.
The 2D ROADM system can be deployed in protected or unprotected point-to-point, linear, and ring applications across distances up to 1000km with no regeneration required. Additionally, the 23 inch 2D ROADM can interoperate in existing networks with the 23-inch standard configuration and the 19 inch small configuration systems with access to all wavelengths.
The FLASHWAVE 7500 Extension configuration allows a remote tributary shelf to be placed away from a 23-inch standard configuration or 19-inch small configuration while supporting access to all 40 wavelengths.
The 10gbps Flexponder unit provides flexible interface and multiplexing/demultiplexing for up to eight client signals in the 23-inch standard configuration, 19-inch small configuration, 2D ROADM configuration, and Extension configuration. The unit supports advanced traffic management features, including non-blocking time-slot assignment (STS-1/STS-3c/STS-12c/STS-48c), ADM on a wavelength, VCAT, and hairpinning. The 10 Gbps Flexponder unit multiplexes up to eight gigabit Ethernet, OC 3, OC 12, and OC 48 signals into a single 10.7gbps optical signal with digital wrapper. ITU-T compliant narrowband optics allow the signal to be mapped to any of 40 channels.
