    摘要： An optical connector according to the present disclosure includes: optical transmission paths that have end faces aligned in a predetermined region, and transmit optical signals. The optical transmission paths correspond to transmission channels or reception channels. The optical transmission paths of the transmission channels are distributed and arranged on a periphery of the predetermined region as compared with a case where the optical transmission paths of the transmission channels are concentrated and arranged at a center of the predetermined region. This configuration can increase an output of an optical signal, and make it possible to improve transmission quality at a low cost while improving a safety standard.

    摘要： Light signal transmitter units 21-1 to 21-n of a transmitter device 20 perform optical communication with a receiver device 40 via optical fiber cables 61-1 to 61-n of an optical interface cable 61. A connection detection unit 22 detects whether connection to the receiver device is established via the optical interface cable, and a visible light source control unit 24 causes a visible light source unit 25 to emit visible light that can identify by an attribute a connection relationship with the receiver device connected via the optical interface cable, only when the connection to the receiver device 40 is not detected, and causes visible light superposition units 26-1 to 26-n to superpose the visible light on the cable. The receiver device also superposes on the cable the visible light that can identify by the attribute the connection relationship with the transmitter device connected via the optical interface cable, only when the connection to the transmitter device 20 is not established, in the same way as the transmitter device. The connection between the optical communication devices can be correctly and easily performed by using the optical transmission path.

    摘要： A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.
