Abstract:
1. An optical network comprising: a first interface comprising a first transmitter and a first receiver, wherein the first interface is configured to generate an optical signal; a second interface comprising a second transmitter and a second receiver; an optical medium connecting the first and second interfaces wherein the optical medium comprises a midpoint located half the distance between the first and second interfaces along the optical medium; and a plurality of splitter/combiners configured to distribute the optical signal generated by the first interface along the optical medium at respective split ratios, wherein a first split ratio of a first of the plurality of splitter/combiners is different from a second split ratio of a second of the plurality of splitter/combiners, and wherein a splitter/combiner nearer to the first interface along the optical medium that to the midpoint is configured to drop a higher ratio of power to an optical network unit than a splitter/combiner that is nearer to the midpoint along the optical medium than to the first interface.
