OBP Card

OBP (Optical Bypass Protection) is an intelligent switching system developed by GIGALIGHT for the fiber optic communication field. It is designed to automatically bypass network nodes in the event of a failure, ensuring uninterrupted network connectivity. The OBP system can automatically detect the power supply status and optical signal output status of the network nodes. When a node failure occurs, it performs optical path bypass to prevent the disconnection of the SDH network and maintain overall network connectivity.


Product Features

  • Supports optical bypass protection for single-mode and multi-mode.
  • Supports power-off optical path status preservation.
  • Supports 1+1 (dual transmitter/receiver) and 1:1 (select transmitter/receiver) protection modes.
  • Supports bypass with heartbeat and amplification, allowing bypass even in the event of equipment failure.
  • Wide optical power monitoring range: -50dBm to +25dBm.
  • Short optical path protection switching time: ≤25ms.
  • Supports SNMP-based unified network management platform, management methods include CLI (telnet and console), Web, and NetRiver (graphical interface).
  • Supports local and remote control.
