The inspection of optical fibers in submarines and aerospace is extremely challenging. Fiber
optic cables are installed in tight spaces that are not easily accessible and are subject to harsh
environmental conditions, such as large temperature fluctuations and vibrations. Yet regular
inspection is still necessary.
For those applications LASER COMPONENTS now introduces Viavis most compact OTDR
module, which is available for very short multi-mode fiber optic paths: the 8123AV for the MTS-
6000A platform.
The 8123AV has extremely short dead zones (20 cm or 40 cm) and a dynamic range of 16 dB
at a pulse width of only 1 ns. This combination makes the OTDR immune to high reflections in the
system. This allows even short lengths and intervals between events to be determined precisely.
Measurement is carried out in AUTO mode. To simplify operation, the measurement result can
either be shown in a graphic representation or in symbols. This also makes it easier for non-specialists
to analyze the measurement results.
Predefined measurement configurations can be stored in the device and are available for special
measurement requirements at any time.
