OLP
OLP-Optical Line Protection is a product that is used in the protection of network transmission line, the product can realize optical power monitoring and automatic switching. In optical transmission network, OLP real-time monitoring optical power of working optical fiber and standby optical fiber. When the optical power value of working optical fiber is below the switching threshold, the system raise the alarm promptly and switches to backup fiber automatically, which achieve line protection of optical transmission system.
Product Features
l Low insertion loss

l Support auto/manual switch
l Support main and backup link real time monitoring
Product Applications
l SDH network
l IP network
l C/DWDM network
l Other optical network
