Fujitsu Network Communications this week announced that\u00a0SBC\u00a0is deploying FNC's multiservice optical transport platform in its network.SBC has installed over 100 of FNC's Flashwave 4500 next-generation SONET add\/drop multiplexers to serve as an optical hub for multiple new and existing SONET rings. The system will also support Ethernet services across those rings.The Flashwave 4500 is a 20-slot, 864-by-864 non-blocking STS-1 grooming and cross-connect system that also supports integrated dense wave division multiplexing. One shelf in a third of an equipment bay can support two OC-48\u2019s or a full OC-192 worth of traffic, FNC claims.The installation is continuing, says Bob Laurent, FNC manager of product marketing. He would not say how many Flashwave 4500s SBC will ultimately deploy nor would he disclose the financial terms of the deal.Initial deployments of the Flashwave 4500 will provide OC-3, OC-12 and OC-48 connectivity with potential for OC-192 configurations, FNC says. The system is being used for both interoffice facility and customer dedicated ring applications, the company says.
