An optical connector of the present invention includes a ferrule to which an internal optical fiber is embedded and an end face grinding is performed; and a connection mechanism which extends to an opposite side of a connection end face of the ferrule, wherein the optical connector butt connects the internal optical fiber and an insert optical fiber which is inserted from outside within a positioning groove provided at the connection mechanism; and a back end side of an end face of the internal optical fiber which butts to the insert optical fiber is made a beveled end face by cutting process.
摘要:
Disclosed is a carbon nano-tube dispersant comprising a highly branched polymer having a repeating unit represented by, for example, formula (12) or (13), wherein the highly branched polymer is produced by the polycondensation of a triarylamine compound and an aldehyde compound and/or a ketone compound in the presence of an acid catalyst. The carbon nano-tube dispersant enables the dispersion of CNTs in a medium such as an organic solvent until the CNTs are so decomposed as to have an individual size. (In the formula, Z1 and Z2 independently represent a hydrogen atom, a phenyl group, a thienyl group, or the like.)
摘要:
Provided is a method for confirming optical fibers connection in a connection part in an optical connector, including: allowing light to pass through a first optical fiber and allowing cladding mode light to disappear; and detecting a difference in light intensity in the connection part between before and after the light from the first optical fiber enters a second optical fiber disposed in the optical connector.
摘要:
An optical connector includes a connector body that has a first optical fiber housed in advance in a ferrule so as to project from a back end of the ferrule opposite to the connecting end surface and an anchoring fixture that anchors a second optical fiber that is to be optically connected to the first optical fiber, and by pressing the anchoring fixture into the connector body while the second optical fiber is anchored in this anchoring fixture, the anchoring fixture and the connector body are connected to optically connect the first optical fiber and the second optical fiber, and the connecting portion that connects the anchoring fixture and the connector body form a movable connecting portion that is adapted to vary the direction of the anchoring fixture with respect to the connector body.
摘要:
The invention is an optical fiber sheet obtained by adhering together at least two sheets with an optical fiber placed therebetween, and placing a reinforcing tube over a portion of the optical fiber extending from an edge of the sheets, wherein the reinforcing tube is fixed to the sheets by bonding, with the reinforcing tube inserted between the sheets located up and below by an appropriate distance from an edge of the sheets.

摘要:
An optical connector that is assembled onto a terminal of an optical fiber cable including tension bodies. The optical connector includes a housing, a ferrule that is provided in the housing, and a fixing cap that is mounted on the housing. The housing includes a fixing portion of which an outer peripheral surface is provided with a screw portion. While the tension bodies leading from the terminal of the optical fiber cable are interposed between the housing and the fixing cap, the fixing cap is screwed onto and fixed to the fixing portion.
摘要:
An optical connector that is assembled at the terminal of an optical fiber cable that integrates an optical fiber and a tension-resisting member extending in the longitudinal direction of the optical fiber, the optical connector including: a connector body having a stationary portion at the rear end thereof, the stationary portion having a threaded portion formed on the outer periphery surface, and a fixing cap that is screwed onto the threaded portion of the stationary portion, wherein the fixing cap fixes the tension-resisting member that has been drawn out from the optical fiber cable terminal by sandwiching the tension-resisting member between the fixing cap and the connector body when the fixing cap is screwed onto the stationary portion.
