OTDR Lauch Box,Singlemode,G652D,150M/200M/500M/1KM/1.5M/2KM/2.5KM
OTDR Dummy fiber is designed to be used in conjunction with an OTDR to measure complete link loss of a fiber. They are also known as pulse suppressor cables, launch cords, launch leads, receive cables or fiber rings. An OTDR dummy fiber, which connects the OTDR to the link-under-test, discloses the insertion loss and reflectance of the near-end connection.
A fiber ring serves as both a launch cable and a receive cable.
