NFO Launch Cable Fiber+ OS2 fiber ring with test leads, 150m | SC/APC | Measuring an insertion loss of the near-end or far-end connection of a fiber optic link with an OTDR requires a launch or receive test cable. A launch cable, which connects the OTDR to the link under test, reveals the insertion loss and reflectance of the near-end connection. A receive cable, which connects to the far-end of the link, reveals the insertion loss and reflectance of the far-end connection. Launch and receive test cables can range from 150 m to 1 km (or longer) in length | Use with NFO-TOOL-80055
