Abstract: Provided is a connector that includes an optical component and a movable member. The optical component emits light. Light from the optical component is incident upon the movable member and the movable member is movable between a first state taken during non-fitting to a counterpart connector and a second state taken during fitting to the counterpart connector. Incident light incident upon the movable member from the optical component is, in the first state, attenuated and emitted to an outside such that power of the light is lower than power of the light when the movable member is held in the second state.

Abstract: A transmission apparatus is capable of accessing a register of a cable satisfactorily. An inquiry about the presence or absence of a register in a cable connected between the transmission apparatus and a reception apparatus is performed. In response to the inquiry, information indicating the presence or absence of the register is received from the cable. When the information indicates the presence of the register, the register of the cable is accessed so that acquisition of storage data or writing in the storage data is performed.

Abstract: Laser hazard at disconnection can be prevented with a simple structure. A tubular connector exterior, and a block that is incorporated on one end side of the connector exterior and on which a light emission portion or a light incident portion is mounted toward the other end side are provided. The light emission portion or the light incident portion is mounted on the block so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior. The light emission portion is a lens through which light output from a light transmission path is collimated and emitted. At least part of the collimated light emitted through the lens is incident on a light diffusion portion provided inside the connector exterior.

Abstract: 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.

Abstract: There is provided an optical transmitter including an optical connector port and a light emitter. The optical connector port is configured to connect to a connector of an optical cable in a first orientation or a second orientation. The light emitter is configured to transmit the optical signal toward a first region of the connector that reflects the optical signal into an optical transmission line of an optical cable when the connector is connected in the first orientation, and transmit the optical signal toward a second region of the connector that reflects the optical signal into the optical transmission line of the optical cable when the connector is connected in the second orientation different from the first orientation.

Abstract: It is made possible to perform data transmission through a cable satisfactorily. A cable is connected between first electronic equipment and second electronic equipment. The cable includes a current consumption unit that receives supply of current from the first electronic equipment through a power supply line, a current monitor unit that observes a current amount the first electronic equipment is capable of supplying to the power supply line, and an information transmission unit that transmits control information according to the observed current amount to the first electronic equipment. The first electronic equipment controls the state of data to be supplied to the cable, on the basis of the control information transmitted thereto from the cable.

Abstract: [Object] To propose an optical communication connector, an optical communication cable, and an electronic device being novel and improved that have excellent maintenance properties and can prevent parallel light (collimated light) from being directly emitted to the outside of an optical connector during non-optical coupling. [Solution] There is provided an optical communication connector device including: a collimating lens configured to collimate light from an optical transmission path; a refracting section arranged on a leading end side with respect to the collimating lens, and configured to refract and eject light from the optical transmission path ejected from the collimating lens; and a scattering section configured to scatter at least a part of the light ejected from the refracting section.
