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.

OLP 1+1 adopts the mode of dual transmitting and selective receiving. It is widely used in Optical Line Protection System like PDH, SDH system, C/DWDM system, electric telecommunication exclusive net as well as CATV optical net.
