Optical Line Protection Card is a protection system, which is developed for optical fiber line backup. It adopts the advanced fiber line auto switching module component, it can auto identify the fiber line signal status of host and backup system, automatically fiber line switching, to protect system running normally when the main fiber faults occurred, improving the service quality of operators. It is widely introduced into various host and backup protection of trunk lines and different optical line switching networks. Its advantage is that the optical signal can be converted to use directly, small size, economic and safety.
Supporting single-mode, multi-mode optical line protection.
Supporting dual-fiber bidirectional and single-fiber bidirectional protection.
Support 1+1 (double-sending, optional receiving), 1:1 (optional sending and receiving) protection.
Wide optical power monitoring range: -50dBm~+25dBm.
Short optical path protection switching time: ≤25ms.
Supporting SNMP-based unified network management platform, network management mode CLI, WEB, NetRiver (graphical interface).
Supporting local and remote control.
