Abstract
A broadband optical fiber network for conveying signals between subscriber locations and a head end. A coherent light source is used at the head end to generate signals for transmission to the subscriber locations. Successive groups of downstream optical transmission segments followed by optical separators or splitters carry the coherent light from the head end to the subscriber locations. Non-coherent light sources providing broadband optical signals are situated at the subscriber locations. Successive groups of upstream optical transmissions segments followed by optical combiners carry the broadband optical light signals to the head end.
