A composite cablewith a plugattached thereto includes optical fibers, metal wires, a tensile strength fiberand an envelopefor enveloping them and the plugincludes a ferruleof the plug for connecting the optical fiber, a cable clampand a Kevler holder(first fixing mechanism) for fixing the tensile strength fiberand a gasket(second fixing mechanism) for blocking a twist of the envelopeand further includes a joint mechanism () of a detachable traction cap for pulling the composite cableand inserting the composite cableinto piping.

Optical DVI cable system and method of laying cable

The present invention provides an optical DVI cable and optical signal transmission equipment which can prevent the leakage of laser light to the outside. The optical DVI cable includes (1) a transmission side unit having a laser light emitting element unit, and configured and arranged to convert input electrical signals into optical signals and to transmits the optical signals, (2) a reception side interface unit configured and arranged to receive the optical signals transmitted from the transmission side interface unit, and (3) a connecting cable having metal wires to supply power to the laser light emitting element unit, and optical fibers to transmit optical signals. The transmission side unit may include a power supply terminal. In this case, the metal wires supply power to the laser light emitting element unit from the transmission side unit via the reception side unit.

Optical DVI cable, optical signal transmission equipment and optical signal transmission system which have the cable, and method of transmitting optical signal using the cable

A digital signal transmission cable and digital video display system are configured to transmit digital signals over long distances. The digital signal transmission cable has a first metal wire and a male digital visual interface connector that is mounted to one end of the first metal wire and equipped with a compensation circuit. The compensation circuit is configured to shape and amplify digital signals that propagated through the first metal wire. The digital video display system has a digital signal transmission cable and an image input device and an image output device that are connected by the digital signal transmission cable.

Digital signal transmission cable and digital video display system

An interface module for transmitting a digital video signal includes: a transmitting interface unit which is designed to be connected to a host device for outputting a video signal, and which has a cable connection consisting of a 4-core optical fiber cable and a 4-core male connector provided at one end thereof; a receiving interface unit having a cable connection designed to be connected to a video output display unit and consisting of a 4-core optical fiber cable and a 4-core male connector provided at one end thereof; and an optical cable unit for transmitting TMDS signals consisting of RGB signals and clock signals. The transmitting and receiving interface units are interconnected by the optical cable unit. The transmitting interface unit includes a second integrated circuit outputting identification information (DDC signal) associated with the video output display unit.

Interface module for transmitting digital video signal

A multi-core-fiber optical connector includes a first ferrule and a second ferrule. The first ferrule has a first step defining a first upper surface and a first lower surface. The first upper surface has a plurality of first receiving grooves for receiving the vicinities of leading end portions of optical fibers and engaging portions formed on opposite sides of the first upper surface. The second ferrule has a second step being abuttable against the first step, and defining a second lower surface opposite to the first upper surface and a second upper surface opposite to the first lower surface. The second lower surface has a plurality of second receiving grooves receiving the leading end portions of the optical fibers. The second upper surface has engaged portions engageable with said engaging portions, and is formed with a recess receiving a band-like elastic cushioning member therein. The first and second ferrules are detachably joined with each other in conjunction with the engagement of the engaging portions and the engaged portions.

Multi-core-fiber optical connector

A fiber fixing device for a linear lightguide comprises a tubular chuck and an elastic tubular body. The chuck includes a hollow part along its axis for receiving an optical fiber, a grasp part for grasping the received optical fiber, and a coupling part supporting the grasp part. The elastic tubular body is elastically expanded outwardly in the radial direction and in this state is fitted onto the grasp part of the chuck. Thus, the elastic tubular body exerts an elastic restoring force to radially inwardly press the grasp part which thereby grasps the optical fiber.

Fiber fixing device for linear lightguide

There are provided a connector body having an accommodating recess in which a pair of ferrules and a pair of springs, respectively fitted over a pair of optical fibers, are accommodated, as well as a connector cover. The connector cover is provided with fixing pins, and the connector body is provided with fixing holes into which the fixing pins are press fitted. A spring pressing portion is provided on the connector cover for pressing the spring with a natural length in the direction toward its distal end at two positions when the fixing pins are press fitted into the fixing holes, and for holding the spring in a compressed state when the fixing pins have been press fitted. A guide taper is formed at a tip of the spring pressing portion. A pressing-portion fitting groove for inserting and guiding the spring pressing portion is provided in the connector body.
