摘要： An optoelectronic combination connector includes a plug unit having an optoelectronic converter and a receptacle unit detachably attached to the plug unit. The plug unit has a fiber securing member with a groove, so that an optical fiber cable connected to the optoelectronic converter is secured to the groove with an adhesive. In the optoelectronic combination connector, the optical fiber cable preferably has an outer cover formed of polyvinylidene fluoride or a fluoro-resin.

摘要： A large-diameter core optical fiber and a small-diameter core high optical fiber are fusion-spliced, and the spliced portion is heated to expand the core diameter of a core of the high optical fiber and form a spot size transition portion, whereby spot sizes of the optical fibers are matched and relative refractive index differences thereof are made substantially identical. Subsequently, the optical fiber is cut at an arbitrary position and the spliced portion and the spot size transition portion are placed inside a ferule with the large diameter core optical fiber arranged on a light incident and outgoing end face side of the ferrule to form an optical fiber component. The core diameter is expanded while monitoring transition loss of the splined portion to obtain an optical fiber component having an optimal spot size transition portion without an advanced technique and without increase in transition loss.

摘要： Provided is a device for removing coating on an optical fiber. The device has a cutting depth limiting surface disposed on a receiver body and a cutting blade attached between a pusher body and a fixing block. The cutting blade is made from plastics and has a specified bending elasticity. An optical fiber is inserted between the cutting blade and the limiting surface. During operation, the cutting blade cuts into a covering on the optical fiber. A high precision in arranging the cutting blade is not required.

摘要： An optical fiber ribbon includes a plurality of optical fibers arranged in a row and an outer coating formed around the optical fibers. Each of the optical fibers has a core, a cladding, and a non-strippable thin coating made of synthetic resin with a Young's modulus of 50 kg/mm2 to 250 kg/mm2 at room temperature and coated around the cladding. The concentricity of the core to the diameter of the non-strippable thin coating is 1 &mgr;m or less.
