Optical Performance Monitoring
DWDM Optical Performance Monitoring (OPM) for Quality of Service (QoS) in metro and longhaul telecommunications fiber optic networks. Short wave IR linear arrays are integrated into a larger optical power monitors (OPM) or optical channel monitor (OCM) to detect the light shooting across the fiber optic cable; the OPM then reports network statistics. An OPM or OCM is required for real-time reporting of vital optical communication network statistics. These module-level spectrum analyzers provide C-band, L-band, and CWDM measurements of optical power, channel count and optical signal to noise ratio (OSNR) with direct feedback to transmission and reception control in central office terminals and EDFA amplifier nodes.
