产品概述:
OBP光保护板是一种应用于光纤通信领域并能自动绕过故障的网络节点的智能切换系统,能自动识别网络节点供电状态及光信号输出状态,节点故障时进行光路旁路,从而能避免网络节点发生SDH 网络的断开,保持整体网络连通性。
功能特点:
- 支持单模和多模光线路保护
- 支持1+1(双发选收)保护、1:1(选发选收)保护
- 支持旁路蓄电放大保护
- 支持自动和手动工作模式
- 支持心跳旁路,实现设备故障也能旁路
- 支持光功率监测范围: -50dBm ~ +25dBm
- 支持光路保护倒换时间: 小于20ms
- 支持光接口: LC/UPC、LC/APC可选
- 支持掉电光路状态保持功能
- 支持本地和远程控制功能
- 支持SNMP网管
