Tests show that Fujitsu's OC-192 Sonet ADM works with Siemens long-haul DWDM gear
April 13, 2000
Fujitsu Network Communications, Inc., and Siemens Information and Communication Networks Inc. recently completed successful tests on the interoperability of Fujitsu's FLASH™-192 advanced OC-192 add/drop multiplexer and Siemens' TransXpress Infinity MTS long-haul optical dense wavelength division multiplexing (DWDM) networking platform. Siemens and Fujitsu conducted the tests in Siemens optical networking labs in Boca Raton, Fla. Both companies recognize the importance of open systems and compatibility in developing multi-vendor route engineering on optical networks without sacrificing performance.
In the tests, Fujitsu's versatile 10 Gb/s Synchronous Optical Network (SONET) terminals and Siemens' powerful DWDM platform proved to deliver practical value in a multi-vendor solution. For example, one of the tests demonstrated that error-free transmission with sufficient system margin can be achieved on six 90 km spans of non-zero dispersion shifted fiber, with 29 dB loss per span, without the need to modify the respective engineering rules for dispersion management. The interoperability test results demonstrate that open platform solutions are feasible when companies design their products to a high degree of excellence.
The TransXpress Infinity MTS system combines high-performance features on an open dense wavelength division multiplexing (DWDM) platform, and its compact modular design makes it particularly attractive to inter-exchange carriers. It can haul data at 320+ Gb/s and transport information for 600 km over non-zero dispersion shifted fiber without regeneration -- the longest transmission length capability of any available product with similar capacity throughput.The FLASH-192 system is for high-capacity transport in interoffice and interexchange carrier network applications. It has an integrated 768x768 cross-connect switching matrix, enabling carriers to drop a full 20 Gbps of bandwidth capacity. It also features hairpinning among lower-rate optical tributaries and full interconnect support up to a four-fiber bidirectional line-switched ring architecture. The FLASH-192 can also be integrated with Fujitsu's FLASHWAVE™ 320G DWDM system.
