Abstract
A method includes transmitting a plurality of time-division-multiplexed return channels from a plurality of optical network terminal outputs to a plurality of cable modem termination system inputs. Transmitting the plurality of time-division-multiplexed return channels includes transmitting a plurality of frequency-division-multiplexed return signals from the plurality of optical network terminal outputs to the plurality of cable modem termination system inputs. An apparatus includes a plurality of optical network terminals; an optical receiver coupled to the plurality of optical network terminals; an optical splitter coupled to the optical receiver; a plurality of cable modem termination system inputs. A plurality of time-division-multiplexed return channels are transmitted from the plurality of optical network terminals to the plurality of cable modem termination systems and the plurality of time-division-multiplexed return channels include a plurality of frequency-division-multiplexed return signals.
