About Launch and Receive Fibers
Launch and receive fibers give the troubleshooter a better view
of the first and last connectors in the link. If you do not use a
launch fiber, the troubleshooter cannot detect the loss of the
first connector in the link. If you do not use a receive fiber, the
troubleshooter cannot detect the loss of the last connector in
the link. Also, the reflectance measurement for the first and last
connectors will be inaccurate. Fluke Networks recommends that
you use launch and receive fibers. The fibers must have a
minimum length of 30 m (98 ft).
When you use launch and receive fibers, be sure to subtract
their lengths from the length measurement to get the actual
length of the fiber you are testing.
