This is an high precision Mandrel Free Insertion
and Return Loss test station, which is widely
used to measure insertion and return loss value
for optical fiber, passive components, and fiber
optical communication system. This test station
also available for dual channel design, which is
highly speed up the testing efficiency. This is a
useful tool which makes efficient measurement
for the optical return loss and also provides a
good solution for the return loss measurement
on the optical fiber cable which cannot wrap
during measurement.
