Abstract: Optical networks may be deployed within hospitals and other structures for permitting bi-directional optical communication. The networks include couplers that permit the network to branch out into multiple sub-networks and hubs. Each of these couplers functions as a junction box and can be used to couple with other networks, such as the Internet or other third party service providers, and can also be used to branch off signals off o main backbone. Furthermore, these couplers may be used to couple signals off of the backbone or a subnetwork toward a specific individual unit. The networks include bi-directional optical amplifiers which compensate for losses associated with the various couplers dispersed throughout the network.

Abstract: The present invention provides an expandable and cost-effective high capacity optical communication system using wavelength-division-multiplexing, optical direction guide means and bidirectional transmission of data over an optical waveguide. The use of interleaved bidirectional data channels reduces the minimum spacing between data channels, permitting a greater number of channels over a single optical waveguide.

Abstract: A bi-directional optical signal transmission network comprises an outbound (12) and an inbound (14) fibre each including an optical amplifier/repeater (18/24). An optical coupling (30, 38, 40) communicates between one of the fibres (12), to the output side of the amplifier/repeater (18) and the other fibre (14). The coupling includes a filter (40) which is arranged to permit transfer of a test signal wavelength between the outbound (12) and the inbound (14) fibre but which prevents transfer of unwanted traffic signal.

Abstract: The apparatus of the present invention includes an audio encoder (19) and decoder (21), a memory (27), a transmitter (38) and a receiver (40) that are optically coupled to an optical fiber (17), and a controller (23). The audio encoder (19) produces samples of an audio input at a regular rate. The samples are accumulated in the memory (27). When enough samples have been accumulated, the transmitter (38) begins to transmit the accumulated samples over the optical fiber (17) in a burst. After transmitting, the apparatus pauses long enough to allow reflections on the optical fiber (17) to attenuate to an undetectable level. Then, the receiver (40) is actuated to receive any incoming burst of data, wich are stored in memory (27) until sent to the audio decoder (21).

Abstract: A fiber optics communication link (20) for a remote mobile (22) vehicle employs a single strand of optical fiber (26) to convey control data from a stationary control station (24) to the vehicle and to simultaneously convey environmental data generated by transducers carried by the vehicle back to the control station. At the control station, the received optical signals are converted to an electrical form and demodulated to recover the environmental data. Additionally, encoded and modulated optical signals corresponding to the control data are provided to the second combiner/splitter (56) for transmission via the fiber to the first combiner/splitter (36). At the vehicle the received optical signals are converted to electrical form, decoded and demodulated to recover the control data, and used to control the vehicle and transducers. Frequency multiplexing is used in different directions along the single fiber in order to eliminate noise due to reflections along the optical path.

Abstract: A connector compatible fiber optic replacement module for use in a local area network coaxial hub (192) for direct communication with TTL level signals to provide a fiber optic communication link. The system uses a first amplification stage (20) having a circuit design which provides a precisely controlled input impedance to allow unit to unit repeatability of response of the circuit in a simple and easy manner. High-frequency response of the circuit is provided by a cascode transistor (50, 70) configuration which limits the effects of virtual capacities. Direct coupled biasing (52, 56, 58) is employed throughout the receiver circuit to limit the number of components utilized. The transmitter circuit employs a standard TTL open collector driver circuit (126) used in peripheral units to drive an infra red (140) LED for transmission over fiber optic communication link.
