DALLAS -- Proximion Fiber Optics, a provider of Optical Layer Monitoring that safeguards and enhances the performance of optical networks, has received the Network Equipment Building Standard (NEBS) Level 3 certification for its high-end optical performance monitor WISTOM. The successful completion of NEBS testing ensures WISTOM deployment in carrier-class environments and gives Proximion the mark of excellence that service providers look for when evaluating equipment for safe and reliable operation in their communication networks. WISTOM's unique test and measurement capabilities allow it to detect, locate, and isolate faults quickly in optical networks. WISTOM is available as a stand alone or embedded unit and is based on a proprietary, extremely fast scanning filter, containing no moving parts, which is used to scan through the optical C or L band. The resolution of the device is sufficiently accurate even for the densest channel spacing. The scanning filter's impressive speed enables protection switching, the total scan time across the optical C or L band is less than 0.1 ms, scanning more than 10,000 times per second. Deployed as an optical performance monitor, WISTOM allows the detection of a faulty or degrading network component and enables rerouting before the 50 ms SONET buffer has been exhausted and the communication breaks down.
