4 December 2002 -- Sweden's Proximion Fiber Optics has received the Network Equipment Building Standard (NEBS) Level 3 certification for its high-end optical performance monitor WISTOM.
During the certification process, Proximion's equipment went through rigorous testing to ensure that it would meet certain environmental and quality standards allowing for the safe and reliable operation of WISTOM in networks. Issued by Telcordia Technologies, NEBS requirements are industry design standards that demonstrate WISTOM's ability to endure events such as flammability, Zone-4 earthquake vibration, thermal shock, temperature changes, mechanical shock and electrostatic discharge. The NEBS testing was completed by Wyle Laboratories in Huntsville, Alabama.
"WISTOM passed the rigorous testing process without a single remark, which indicates that the Telcordia requirements has been considered from the start of the design," says Barbara Brooks at Wyle Laboratories.
WISTOM's 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 scanning filter's speed enables protection switching, the total scan time across the optical C or L band is less than 0.1ms, 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 50ms SONET buffer has been exhausted and the communication breaks down.
