Avanex Corp. announced the availability of a line of optical protection switch (OPS) plug-in modules for its PowerNode platform. The OPS modules are used for fiber link, equipment or client side protection and have switching speeds of 10ms, which allows sub- SONET/SDH optical protection. The OPS product portfolio is designed for both system OEM and carrier customers.

According to Avanex, service level agreements are increasingly demanding with severe penalties for loss of service. In the event of facility failure or fiber breakage, service providers have implemented optical protection switching in addition to traditional SONET/SDH restoration. The OPS modules monitor the optical power on the incoming fibers. Upon detection of faults, the OPS module toggles the bypass switch to activate the protection path within 10ms.

"The Avanex OPS offers optical protection using Avanex's proprietary optical switch technology," said Avanex CTO Giovanni Barbarossa in a statement. "OPS solutions are offered at module, line card and network ready levels, and are now being tested or deployed by multiple tier-one customers."

Avanex offers the solution through its PowerNode Flexible Optical Layer platform. Using standard SNMP or TL1 interfaces, the OPS can be directly deployed and managed as a stand-alone network element within an optical network node. The OPS solution is modular and designed as a plug-and-play module for Avanex's PowerNode platform and provides single or dual path optical protection for SONET/SDH and CWDM/DWDM applications.
