CWDM Solutions

Raisecom's Coarse Wave Division Multiplexing (CWDM) Solution allows scalable and easy-to-deploy Gigabit Ethernet (GbE) services in metro-area networks, data center, and campuses. The combination of CWDM SFPs and CWDM Optical Add-Drop Modules (OADMs) and Multiplexers enables the design of a flexible and highly available multiservice access network. Since optical fiber has become the most popular means of telecom transportation, incumbent carriers would like to use fiber to access and aggregate users, providing flexibility and bandwidth on demand. OPCOM series CWDM systems are capable of transporting multiple independent services from 2, 4, to 8 in one single pair of fiber (single strand fiber can provide 2 or 4 service channels), without interference to adjacent service channel. They have enabled carriers to expand their transportation capability smoothly and conveniently, in terms of removing works of digging holes and planting new fibers. Also, from the economy prospective, deploying two equipment point to point will be more cost effective than planting new fibers at metropolitan area. Here is one of the examples -- delivers 2Gigabits bandwidth to 18 campuses using one pair of fiber in a daisy-chain configuration.
