Frequently Used Terms
PMD scale Sets the best scale to measure a PMD of this value.
PMD section The PMD value of a fiber section
Pulse width Width of the OTDR pulse, in nanoseconds, used to
measure the link. A longer pulse allows you to probe
further along the fiber, but results in a lower resolution.
A shorter pulse width provides higher resolution , but a
smaller distance range.
RS-POTDR Random-scrambling tuneable polarization-sensitive
OTDR
Sensitivity Sets the electronic sensitivity.
SOP State of polarisation. Here, SOP has a broader sense: it
means a group of OTDR traces taken at different
frequencies, but with the same SOP. The SOP is the unit
that is used to compute the distributed PMD curve.
SOA Semiconductor optical amplifier
