SC/FC/ST/LC-APC/UPC OTDR Launch Cable Ring From 500m To 2KM
The OTDR launch fiber box is used with optical time domain
reflectometers to help minimize the effect of the OTDR launch pulse on measurement
uncertainty. Units are available in any length up to 2km and housed in a rugged, airtight
or watertight carry case.
