The OWM (Optical Wavelength Manager) is a cost-effective SNMP-managed solution for optical monitoring of DWDM networks, accurately measuring the optical power, wavelength, and OSNR (Optical Signal to Noise Ratio) of 100 DWDM channels simultaneously with an update time of 10ms across the entire spectrum.
The Sentior 27000 is designed to accommodate an integrated OCM, thus providing a smooth upgrade path to the full functionality of RED-Cs advanced Self Managed EDFA, whose features include, amongst others: Closing the spectral loop of the EDFA; Providing network management with accurate and updated channel power and OSNR measurements; On line calibration of the OCM unit; and reduction of space and cost requirements.
Benefits include: 1) a stable optical system during spectral and power variations, 2) seamless and coordinated transient control, 3) mitigation of ROADM insertion loss and associated OSNR penalty, 4) complete East/ West separation eliminating any single point of failure, 5) full spectral monitoring capabilities and 6) an integrated system interface.
