Overview
A Splitter/Combiner cable of module connect between dual-fiber and single-fiber optical signals, potentially doubling
the data capacity of the installed fiber plant. Separate Tx and Rx signals from a dual-fiber optical device using the same
wavelength over two fibers can be combined through the Splitter/Combiner onto a single bi-directional strand of fiber
for the long and expensive run to the remote site.
Another Splitter/Combiner at the remote site splits and combines the signals for the dual-fiber device at that location.
Splitter/Combiners are fully passive, and they operate at a specific wavelength. They are transparent to networks and
protocols. A pair of cables, as in the example above, attenuates an optical signal by no more than 7 dB on either single-
mode or multi-mode fiber. Signal reflections are effectively eliminated with angled polished connector (APC) at the
single-fiber “common” interface.
