Corning Bare Fiber Test Spool With FC/SC/LC/ST,SMF G652D/G657A 250um OTDR Test Launch Cable,OTDR Dummy Fiber Box
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.
