Abstract:
Apparatus for distributing optical transmission paths comprising:a plurality of first optical fibers bidirectionally transmitting light at a first wavelength, each one of said plurality of first optical fibers having a first portion spliced to a second portion; a like plurality of second optical fibers transmitting light at a second wavelength; a like plurality of third optical fibers for simultaneously transmitting light at both said first and second wavelengths, each one of said plurality of third optical fibers having a first portion spliced to a second portion; a like plurality of wave division optical couplers, each having a first port connected to one of said plurality of first optical fibers, a second port connected to one of said plurality of second optical fibers, and a third port connected to one of said plurality of third optical fibers such that light having said first wavelength and received at said first port is combined with light having said second wavelength and received at said second port and said combined light is provided as an output to said third port, and light received at said third port as an input and having said first wavelength is provided as an output to said first port; and a support structure for supporting said first, second and third plurality of optical fibers and said wave division optical couplers.
