Sorrento Networks announces interoperability with Hitachi Telecom USA Inc. long-haul Optical networking systems

Fiber Optics Weekly Update, June 7, 2002

Sorrento Networks and Hitachi Telecom USA Inc., a subsidiary of Hitachi America Ltd., a provider of telecommunications equipment including long-haul DWDM systems and SONET, announced successful completion of interoperability testing demonstrating optical transport over both Hitachi Telecom's long-haul and Sorrento's metro/regional optical networking systems.

Interoperability testing between Sorrento's GigaMux DWDM optical transport platform and Hitachi Telecom's AMN 7100 with micro-Transmux systems empowers telecommunications and cable/MSO carrier customers to select a pre-tested long-haul and metro network solution. Successful end-to-end interoperability was demonstrated using OC-48 (2.5 Gbps) and OC 192 (10 Gbps) signals with and without forward error correction (FEC).

Sorrento Networks' GigaMux is a metro and regional DWDM platform that expands the capacity of a new or existing fiber network up to 64 times, transforming any fiber plant into a high performance, multi-protocol transmission network. GigaMux is a compact, flexible and cost-effective system based on a "pay as you grow" architecture. Sorrento's EPC product family consists of sub-rate access aggregation multiplexers that increase bandwidth utilization by aggregating a wide variety of traffic for transmission over a single wavelength. Jump Start-400 is the company's 4-channel coarse wavelength division multiplexing (CWDM) platform targeted at storage area and simple network extension applications.

Hitachi's AMN 6100/7100 product line offers multiple rate inputs, ultra high channel count and ultra long-haul capabilities in a single platform. The products offer scalability to 128 10 Gbps signals, and support 100 GHz ITU grid spacing with in-service upgradability to 50GHz lTU grid spacing. Flexible optical add/drop multiplex (OADM) capabilities enable optimization of the network configuration according to traffic demands. Output power control automatically maintains constant per channel output power to ensure reliable, robust transmission under changing conditions.
