Multiple Choice

The OLPM Card provides in-service, multi-port optical power monitoring for CWDM/DWDM deployments, giving operators instant visibility of receive/transmit levels across critical line and monitor ports. By tracking span loss and amplifier balance in real time, it helps prevent outages, shortens MTTR, and simplifies turn-up and routine O&M.
Low-loss tap inputs ensure measurements without interrupting traffic, while configurable thresholds and hysteresis generate precise alarms for drift, fiber cuts, or mispatches. The card reports to your NMS via Web/CLI/SNMP and supports automation through Netconf/YANG, fitting seamlessly into 1U/2U/5U chassis alongside MUX/DEMUX, EDFA/Raman, OLP, and OCM modules.

  • Multi-port line power monitoring (e.g., 1/4/8-port options)

  • In-service measurement via low-loss tap; no traffic disruption

  • Configurable thresholds, LOS/LOP alarms, historical trending

  • Web/CLI/SNMP management; Netconf/YANG for orchestration

  • Works with G.652/G.657 SMF; LC/SC front panel options

  • Platform backplane power; low consumption for POP/IDC sites
