datasheet optical communications systems? overview a splitter/combiner cable of module connect between dual-fi ber and single-fi ber optical signals, potentially doubling the data capacity of the installed fi ber plant. separate tx and rx signals from a dual-fi ber optical device using the same wavelength over two fi bers can be combined through the splitter/combiner onto a single bi-directional strand of fi ber 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-fi ber device at that location. splitter/combiners are fully passive, and they operate at a specifi c 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 fi ber. signal refl ections are eff ectively eliminated with angled polished connector (apc) at the single-fi ber common interface. passive splitter/combiners (dual-fiber to bi-directional single-fiber) highlights double fi ber capacity between single-fi ber sources transition between dual-fi ber and single-fi ber 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 1 40 km dual-fiber single-fiber central office
