Abstract: Systems and methods for relaying upstream signals received from a plurality of subscribers to a remote head end. Some preferred embodiments include upstream transmitters in one or more Optical Network Units that may be dynamically and individually controlled to determine whether the upstream transmission is in burst mode or continuous mode.

Abstract: Methods and systems that reduce power usage in a CATV network. Power usage may be reduced by temporally adjusting the power output of amplifiers in the network. The power output of one or more amplifiers in the network are preferably adjusted based on patterns of temporal usage of the network.

Abstract: A multimode combiner or coupler (MMC) may combine the inputs into a larger core multimode fiber. The multimode combiner may be combined with a re-transmitting laser for detecting and re-transmitting signals. Thus, the multi-mode combiner may detect and combine input signals, and then retransmit the detected, combined signal. The detection can be implemented with multiple single mode fibers to small single mode detectors or a multi-mode coupler with a larger multi-mode detectors. In embodiments of the MMC, a bi-directional optical splitter/combiner includes a transmitter for re-transmitting an RF signal received at a receiver, a first wave division multiplexer (WDM) combiner combining the output of the first transmitter in an upstream direction to a downstream signal in a downstream direction, and a second WDM combiner combining split downstream signals in the downstream direction with upstream signals received via at least two optical fiber inputs.

Abstract: Systems and methods for achieving full duplex bidirectional transmission across coaxial cable in a hybrid fiber-coaxial cable TV network. Some preferred systems and method will attenuate reflections propagated within the coaxial cable. Other preferred systems may echo-cancel reflections propagated within the coaxial cable.
