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.

Abstract: Implementing a laser into a system that uses a remote powered combiner or an aggregating combiner (AC) with one or more in-range contributing combiners may provide power to the downstream contributing combiners (CC). The power may be provided on the same fiber that downstream signals and the upstream signals traverse.

Abstract: A bi-directional optical transceiver includes multiple single mode optical ports and a multi-mode optical port. A multi-mode optical combiner combines single mode optical signals received at the single mode optical ports into a multi-mode optical signal at the multi-mode optical port. Each single mode optical signal has a distinct optical mode that does not interfere with the optical mode of the other single mode optical signals. A photo detector detects a total optical power of the plurality of single mode optical signals in the multi-mode optical signal. An amplifier is coupled to receive an output of the photo detector.

Abstract: An optical combiner for a communications network transmitting both upstream signals and a downstream optical signal. The communications network includes an array of amplifiers, each receiving a respective instance of the downstream optical signal. The output of each amplifier is split among a plurality of ports in a first splitter/combiner unit. The first splitter/combiner unit transmits the amplified downstream optical signal to respective second splitter/combiner units.

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: Powering an active/splitter and providing information to ONUs to cause adjustments to ONU operating wavelengths. An ONU may identify the port of a splitter to which the ONU is connected in order to make wavelength adjustments. Various techniques enable the ONU to identify from which port the ONU is receiving signals, such as a splitter that splits signals to ONUs in a cable network and signals to one or more ONUs the port to which it is connected. The splitter may lack electrical power and may perform the signal function by harvesting optical power from optical power provided to the splitter. In this manner, an active splitter may behave passively with respect to powering components in the absence of electrical power.
