Product Overview

Optical line protection system is combined of OLP-Optical Line Protection and operation maintenance terminal; it can realize optical power monitoring, optical line auto-switchingand network management etc.

In optical communication network, OLP monitors optical power of optical fiber and standby optical fiber at real time. In case the current optical power of optical fiberis less than pre-set switching threshold value, then alarm is on and it would switch to standby optical fiber automatically to protect optical transmission system line.

OLP can provide a  protection scheme for all routes andmain lines easily with low cost, can protect all networks which needs opticalline switching, all these above can make a optical communication network with no-block,highreliability,safety and high anti-disaster strength.

Features

l  Reduce interrupt time of communication and improve maintenance efficiency with quickly recovering communication

l  Remarkably reduce damage to network caused by fiber failure

l  Increase network reliability and improve service quality

l  Harmless switch between working path and secondary path and convenient forline overhaul and  cutover

l  Real-time monitoring power level of fiber

l  Support remote control, easy management and maintenance

l  Transparent transmission

Typical Application

The diagram of optical line protection system is as shown below:

Telecom transmission equipment are located in core computer room, belong to central office client equipmnet.H15FOLP serials equipment are also stored in the computer roomTelecom equipment TX port is connect to H15FOLP Tx port,T1 is connected to the main fiber,T2 is connected to the backup fiber. As the same, telecom Rx port is connected to H15FOLP Rx port, R1 is connected to the main fiber, R2 is connected to the backup fiber. The network management interface of H15FOLP is connected to telecom DCN network for the remote maintenance of OLP system on the entire fiber topologies.
