There is provided a holder for an optical fiber ferrule end face grinding apparatus that can make good use of a grinding film, in which the number of optical fiber ferrules held by the holder is greatly increased. The holder includes a holder plate including a plurality of insertion holes into which each of the ferrules is inserted. In the holder plate, the insertion holes are arranged in an area of a certain size extending from the center to the periphery thereof.

Holder for optical fiber ferrule end face grinding apparatus

A ferrule holder assembly for an optical-fiber-end-face grinding apparatus comprises a ferrule holder board supported to be moved upward and downward in parallel with a grinding board of the optical-fiber-end-face grinding apparatus, a ferrule sleeve provided at the ferrule holder board for receiving and supporting an optical fiber ferrule while putting the tip at the grinding board, an adapter for retaining the optical fiber ferrule or a connector for supporting the optical fiber ferrule in a state where the optical fiber ferrule is inserted into the ferrule sleeve, and an urging unit for urging the adapter in a direction opposite to the grinding board from the ferrule holder board.

Holder for an optical connector end-face polishing machine

A ferrule heating apparatus, which is configured to heat a ferrule and thereby adhere an optical fiber and the ferrule together, includes a plurality of ferrule housing portions capable of freely housing and aligning ferrules, a holdermade of a thermally conductive member, a holder heating unitfor supporting and heating the holder, and a temperature control unitfor controlling a temperature of the holder heating unit. The holder heating unitand the temperature control unitare provided mutually separately. Meanwhile, the holder heating unitand the temperature unitare mutually connected to each other through an electric power cable

Ferrule heating apparatus and method of adhering ferrule and optical fiber

The center of a turntable moves around the central axial line of an autoroation disk along the circular orbit C of a smaller diameter than that of an autorotation disk . Thus, the turntable revolves both around a center point O and on its own axis in accordance with an autorotation of the autorotation disk . A polishing holder holds a connector of an optical fiber polished by a polishing film arranged on the upper plane of the turntable . An optical fiber end face polishing machine provided with a memory for storing a control program which allows a control device to execute predetermined polishing steps, the control device being for controlling an autorotation motor of the turntable and a revolution motor thereof.

Optical fiber end face polishing machine

The present invention provides a polishing apparatus for optical fiber end surface making it possible to freely adjust the contact pressure between a polishing plane and the distal end face of a ferrule and capable of preventing a defective product from being produced under polishing. A control circuit drives a vertically driving mechanism to allow a ferrule holding plate to move from a preparation state to a ferrule polishing starting state and by compressing a spring it then allows the ferrule holding plate to lower further beyond the starting state to complete the polishing.
