The Digital Lightwave OWM Series 2 is a high-performance optical layer monitoring system, combining the features of an optical spectrum analyzer and a fast optical channel monitor. It is ideal for both DWDM long haul and metropolitan area network applications.

The OWM Series 2 monitors the spectral characteristics over the C Band including central wavelength, power level, Optical Signal to Noise Ratio (OSNR) and Spectral Width, measured as Full Wavelength Half Maximum (FWHM). Any channel deviating from normal conditions is reported within milliseconds. Long term drift of these parameters can be tracked and analyzed, thus providing input for network tuning and resource allocation. The OWM Series 2 enables service providers to resolve channel specific problems, in some cases even before a degrading channel suffers critical data loss.

This translates into less costly network downtime and the ability to avoid violation of service level agreements (SLA). The unique measurement performance of OWM Series 2 also enables diversified billing models and SLA supervision.
