Provided is an optical fiber having identification mark, which includes an optical transmission medium (exemplified by glass fiber) including a core part and a cladding part, a primary resin layer coating the optical transmission medium, and a secondary resin layer coating the primary resin layer, in which identification marks for optical fiber identification (exemplified by continuous identification mark) are provided on a surface of the secondary resin layer at a predetermined interval along an axial direction of the optical transmission medium. An effective area of the optical transmission medium at a wavelength of 1550 nm is 90 &#x3bc;mor more, the predetermined interval is 100 mm or more and 500 mm or less, and a Young's modulus of the primary resin layer is 0.9 MPa or less.

Optical fiber having identification mark and manufacturing method for optical fiber having identification mark

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.
