1+1 Optical Line Protection System for Fiber Protection, Bi-directional Protection in SMF, LC/UPC, Plug-in Card Type

OLP-Optical Line Protection is a device that is used in the protection of network transmission line, it can realize optical power monitoring and automatic switching. 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 fiber is 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.

In 1+1 operation, a splitter bridge sends the Tx signal to both line and a 2x1 selector switch selects the signal from one of the line. When line failures, the selector near the Rx side of the failed traffic detects the failure, switches over, and selects the traffic from the backup line. It ensure the transmit system working normal even the main fiber was broken. It widely used in a variety of system, including: PDH, SDH, C/DWDM and CATV networks for optical fiber protection.
