fbg reflector 1550

FBG Reflector (1550nm)

OTDR reflector is located at all the optical network unit (ONU) side of a passive optical network (PON), which will reflect the test signal from the OTDR at the optical line terminal (OLT) side, while the traffic signal of PON system will pass through the reflector with very little loss. OTDR reflector is used to help to increase the sensitivity of the OTDR for checking the optical continuity of a subscriber and troubleshooting.


Application Of FBG Reflector (1550nm)


  •  PON network
