1. A device for facilitating a transmission of at least one upstream data signal from at least one subscriber in a communications network comprising:

  • a radio frequency (RF) demodulator operable to receive an RF signal and demodulate the RF signal into the at least one upstream data signal;

    an optical transducer operable to convert the at least one upstream data signal into an optical signal for transmission over a fiber optic link in the communications network, wherein the at least one upstream data signal comprises multiple upstream data signals, each generated by one of multiple pieces of subscriber equipment; and

    a controller operable to receive multiple demodulated data signals representing the multiple upstream data signals, the controller is further operable to combine the multiple data signals into a single data signal in accordance with a multiple-access protocol.
