The significance of return loss
The introduction of new
technologies in optical
transmission systems has created
the need to adapt measurement
techniques for component
characterization.
In particular, this has been the case
since the introduction of single-
mode fiber to optical high-speed
transmission systems. Special
lasers with narrow linewidth have
to be used for the transmission
(these are known as Distributed
Feedback Lasers DFBs). However,
the smaller linewidth the more
sensative the laser becomes with
regard to backreflections.
