Abstract: An optical-to-electrical converter may include and/or involve a splitter to separate one or more narrowcast signals from a broadcast signal, at least one broadcast signal receiver to receive the broadcast signal separated from one or more narrowcast signals, at least one narrowcast signal receiver to receive the narrowcast signal separated from the broadcast signal, the narrowcast receiver including an attenuator and a filter, and a controller including logic to dynamically monitor and adjust the attenuator to maintain separation between the broadcast and narrowcast signals.

Abstract: A optical transmission system includes light sources generating light of at least two wavelengths, where any two adjacent wavelengths are separated by less than 10 nm. The wavelengths fall within the zero dispersion zone of an optical fiber, and may be shifted by 1 nm or less to reduce crosstalk effects.

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 having a distinct optical mode that does not interfere with the optical mode of the other single mode optical signals. A photo detector coupled to the multi-mode optical combiner detects a total optical power of the single mode optical signals in the multi-mode optical signal.
