Optical Bypass Protection (OBP)

The Optical Bypass Protection (OBP) module is designed to provide intelligent switching to bypass faulty network nodes in optical fiber communication systems. It automatically detects the power status of network nodes and the output of optical signals, performing optical path bypass to prevent network disconnection. This ensures continuous operation and reliability of the optical network even in the event of equipment failures.

Description

Description: The Optical Bypass Protection (OBP) module is designed to provide intelligent switching to bypass faulty network nodes in optical fiber communication systems. It automatically detects the power status of network nodes and the output of optical signals, performing optical path bypass to prevent network disconnection. This ensures continuous operation and reliability of the optical network even in the event of equipment failures.

Key Features:

  • Multiple Bypass Modes: Supports single-mode and multi-mode optical bypass protection, offering versatility for different network configurations.
  • Power-Off Status Retention: Maintains the optical path status during power outages, ensuring network continuity.
  • Protection Modes: Provides 1+1 (dual transmit and select receive) and 1:1 (select transmit and receive) protection modes, enhancing network resilience.
  • Heartbeat Bypass: Ensures bypass function even during equipment failure, maintaining network operation.
  • Wide Monitoring Range: Monitors optical power levels from -50dBm to +25dBm, covering a broad range of signal conditions.
  • High Switching Speed: Ensures rapid optical path protection switching time of ≤20ms, minimizing downtime.
  • Comprehensive Management: Supports SNMP unified network management platform with CLI, Web, and NetRiver management modes, allowing for centralized control and monitoring.
  • Local and Remote Control: Offers flexible control options, including local and remote operation, for easy management.
  • Robust Design: Built to withstand various environmental conditions, ensuring reliable long-term performance.
