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
