Abstract
Described herein are devices and methods for facilitating the transmission of an upstream data signal from at least one subscriber in a communications network. The device is operable to receive a radio frequency (RF) signal from one or more subscribers. The RF signal includes at least one upstream data signal. The RF signal is demodulated into the upstream data signal by a RF demodulator in the device, which is then converted into an optical signal by an optical transducer in the device for transmission over a fiber optic link in the network.
