Insertion Loss and Link
Loss Testing:
Paired with a TEMPO 555B or 558B optical
power meter, the 265A
serves as an ideal general purpose 1310nm
laser source for measuring
the insertion loss of single-mode
fiber optic cables and connectors. The
265A can also be used
with an optical power meter for dual wavelength
link loss
testing of installed cable plants.
The 265A laser source is
particularly useful for testing and maintaining
telecommunications systems and other long wavelength single-mode
fiber optic networks operating at 1310nm.
The 265A laser source is fitted
with a precision Universal Connector
Interface (UCI), which
ensures maximum accuracy and repeatability
when performing
critical measurements on fiber optic systems. A compre-
hensive
range of UCI adapters is available for all industry standard fiber
optic connectors.
