产品概述:
OSS光保护板是为了确保重要光纤路由/设备安全通信使用的一种保护板,在发送端用光通道选收器件对发送光通道进行路由选择,光信号只能沿着工作通道或者备用通道2选1传送。可提供主备光纤的实时监控(及同时进行光功率计监控)能有效避免主备路由光纤同时阻断的可能性
功能特点:
- 支持单模和多模光选路保护
- 支持光路2选1保护
- 支持自动和手动工作模式
- 支持光功率监测范围: -50dBm ~ +23dBm
- 支持光选路倒换时间: 小于12ms
- 支持光接口: SC/APC、SC/PC、LC/APC、LC/PC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
- 单板卡支持4路2选1
