Fujitsu Introduces ROADM for MSOs

Fujitsu Network Communications introduced its FLASHWAVE 7500 Small System for small- to medium-sized MSOs. The system combines DWDM, a Reconfigurable Optical Add/Drop Multiplexer (ROADM) switch fabric and multi-rate, high-density Optical Line Cards (OLCs) for services up to 10 Gbps per wavelength in a single 19" shelf.



The new system incorporates many of the same features as the larger 40-channel FLASHWAVE 7500 Core System and the FLASHWAVE 7500 Extension System, including access to single or multiple wavelengths, at any node. For low cost or point-to-point applications where the ROADM switch fabric capabilities are not required, the FLASHWAVE 7500 Small System can be configured as a flexible Optical Add/Drop Multiplexer (OADM) with manual access to all wavelengths. Fujitsu features a dynamic, self-tuning equalization system that adapts power levels as the network grows.



A common set of optical line cards (transponders) support for an array of services, including Gigabit Ethernet, traditional SONET, Storage Area Networking (SAN), Video On Demand (VOD) and transparent wavelength services.



Fujitsu already serves a number of North American MSOs, including Adelphia, Brighthouse, Charter, Comcast, Cox, Shaw and others. Over 220 nodes of its FLASHWAVE 7500 have been deployed in MSO applications. http://us.fujitsu.com/telecom
