Abstract
A splitterless optical broadcast switch (110) for routing a plurality of optical carrier signals. The splitterless optical broadcast switch (110) includes an optical source (112) for generating a plurality of unmodulated optical carrier signals. A first stage routing module (114) routes the plurality of unmodulated optical carrier signals. A modulating module (116) receives a plurality of RF input signals and modulates each of the RF input signals onto any number of the unmodulated optical carrier signals to generate a plurality of modulated optical carrier signals. A second stage routing module (118) routes the plurality of modulated optical carrier signals complimentary to the first stage routing module (114). An output module (120) receives the plurality of modulated optical carrier signals such that the optical output from the optical source (112) is paired to a complimentary optical input of the output module (120).
