Optical distribution network for RF and other analog signals

摘要

An optical network has an optical bus interconnecting a plurality of sources with a plurality of loads. Each source has a tunable laser for transmitting signals at a selective wavelength and each load has a tunable filter for receiving signals at a selective wavelength. As a result, through a single connection per node and a single bus, each source can exchange signals with any load. The optical network employs a passive optical interface device for routing signals between a node and a bus. The optical interface device provides balanced amplification of the optical signals throughout the network. The optical network is able to distribute RF and other analog signals to multiple nodes while preserving signal quality.
