Disclosed is a polishing process and a polishing apparatus for polishing an end face of a connector assembly with at least one optical fiber. The process comprising the steps of attaching at least one optical fiber with an optical connector made of different material from that of the optical fiber so that the optical fiber exposes from the end face of the optical connector and polishing the end face of the connector assembly with the optical fiber while pressing the same against a flat surface of a rotating abrasive wheel containing fixed abrasive grains with a constant load.

Polishing process for optical connector assembly with optical fiber and

An apparatus for assembling and inspecting optical fibers and a connector which attaches the connector to at least one cord end of a plurality of optical fibers and inspects connection loss etc. due to connection of the connector. A process of connecting the connector to the cord ends where the connector is assembled which is linked to a process of processing the other cord ends and then inspecting connection loss etc. of the optical fibers due to a connection of the connector.

Apparatus for assembly and inspection of optical fiber connectors

Disclosed a method of assembly and inspection of optical fiber connectors which attaches connectors to at least one cord end of a plurality of optical fiber cords in which single or multiple optical fibers are accommodated and inspects connection loss etc. due to connection of the connectors. A process of connecting the connectors to cord ends where the connectors are assembled is linked to a process of processing the other cord ends and then inspecting connection loss etc. of the optical fibers due to a connection of the connectors.

Method for assembly and inspection of optical fiber connectors

A method for switching an optical connector having paired optical connectors, having pins engaged with engaging holes of the optical connectors, which involves a connector disposing step of disposing the switching optical connector parallel to the separating optical connector, a pin forward moving step of moving the pins engaged with both the reconnecting and separating optical connectors each other to the reconnecting optical connector side, then a connecting switching step of relatively moving the reconnecting optical connector, the separating optical connector and the switching optical connector and the front end faces thereof, and finally pin backward moving step of moving the pins of the reconnecting optical connector side to the switching optical connector side. Thus, the method and an apparatus for switching an optical connector can momentarily switch to connect optical transmission units with optical connectors without depending upon a worker's skill as well as to mechanize or automate the replacing work.

A cable core self-aligning apparatus comprises core feeding means for holding a plurality of cores, drawn out of an end of a cable, in a line and sequentially feeding the cores; rotational conveyor means having a conveying rotor for holding and rotationally conveying each of the cores to a core extracting position; and core identifying means for identifying the number of each core while that core is being conveyed to the core extracting position by the rotational conveyor means. The cable core self-aligning apparatus also includes a core holder having a plurality of core-positioning sections; core-holder positioning means for setting that of the core-positioning sections which is associated with the number of the core identified by the core identifying means, at the core extracting position when the core holder receives the identified core; and core handling means for holding and inserting the core reaching the core extracting position by the help of the conveying rotor, into the core-positioning section set by the core-holder positioning means.
