Multiple Choice

The OLP – Optical Line Protection module protects critical fiber routes by switching traffic between a working and protection path based on real-time optical conditions. Transparent to protocol and bitrate, it monitors receive power/LOS on both paths and triggers fast switchover (<20 ms typical) when a cut or degradation is detected—maintaining service continuity for DCI, metro, and backbone links.
Configurable revertive/non-revertive logic, hold-off and wobble timers, and hysteresis prevent unnecessary flaps, while alarms and logs support rapid root-cause analysis. The card fits HYD 1U/2U/5U platforms or a 1U stand-alone chassis and interoperates cleanly with MUX/DEMUX, EDFA/Raman, OCM/OTDR, and OLPM modules for end-to-end resilience and observability.

  • Protection schemes: 1+1 optical line, bidirectional; supports power/LOS/degrade triggers

  • Switching: <20 ms typical; auto/forced/manual; revertive/non-revertive; A/B lock

  • Monitoring: per-port optical power, thresholds & hysteresis; event/alarm logs; optional monitor port

  • Management: NMS/Web/CLI/SNMP; Netconf/YANG for automation; dry-contact relay outputs

  • Optics: protocol/bitrate transparent (e.g., 10G/25G/100G/400G); CWDM/DWDM; low insertion loss

  • Interfaces: LC/UPC standard (LC/APC, SC variants optional); G.652/G.657 SMF compatible

  • Power & form factors: −48 VDC (optional AC); hot-swappable card for HYD 1U/2U/5U or 1U rack unit

  • Use cases: fiber cut protection, maintenance bypass, diverse-route protection, ROADM/OADM segment safeguarding
