Optical Communications Systems™ Datasheet Passive Splitter/Combiners (Dual-Fiber to Bi-directional Single-Fiber) HIghlights Double fiber capacity between single-fiber sources Transition between dual-fiber and single-fiber Protocol and network operation transparency Fully passive (no power needed) Low insertion loss (3.5 dB maximum per cable) APC connectors for low 3.5 dB insertion loss 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 singlemode or multi-mode fiber. Signal reflections are effectively eliminated with angled polished connector (APC) at the single-fiber “common” interface.
