JPS6341812A - Simplicated process for terminal processing of optical fiber cable - Google Patents

Abstract

PURPOSE:To surely execute the terminal processing of a cable by tempolarily fixing a hardening agent protection cylinder inserted into the end face of an optical fiber cable so that a cord can be positioned on the center of the protection cylinder, solidifying the protection cylinder and then fitting an optical connector. CONSTITUTION:After removing a casing 3 of an optical fiber cable 1 and inclusions 11, a tension member 5 of the cable 1 is removed with a slight residual time the end of the housing 3. An optical fiber reinforcing tube 6 is cut off at the length of an optical fiber 7 to be used for a cord and then inserted into the optical fiber 7. A sealing putty 9 is applied to the end face of the cable 1 to prevent the cable from the inflow of a hardening agent, the hardening agent protection cylinder 2 is inserted into the cable 1 and fixed on a prescribed position, and the cable side is sealed by a tape to prevent the hardening agent from being leaked. The protection cylinder part is temporarily fixed, a proper quantity of hardening agent 10 is injected, the cord is temporarily fixed and solidified with a centering tool 11 so that the cord is fixed on the center of the protection cylinder 2, and then the optical connector 12 is fitted. Thus, the terminal processing of the optical fiber cable can be simply and surely attained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for terminating an optical fiber cable. Conventionally, when terminating an optical fiber cable, the optical fibers of the optical fiber cable and the optical fibers of the optical fiber cord that have been connector-treated in advance are connected to each other. was spliced and protected in a splicing box.

For this reason, special equipment (fusion splicer) and special parts (splicing box, etc.) are required for the connection, as well as the acquisition of advanced technology, resulting in problems such as high processing and component costs and operational constraints. there were.

The invention that solves these problems is this method of encoding optical fiber without splicing.

The present invention will be explained below based on the drawings.

(b) Remove the outer jacket ■ and inclusions ■ of the optical fiber cable ■.

(b) Remove the tension member ■ of the cable, leaving it slightly behind the outer wave end.

(c) Cut the optical fiber reinforcement tube ■ to the length of the optical fiber ■ to be coded, and attach it to the optical fiber ■.

At this time, on the cable side of the reinforcing tube, expand the tension member (2) of the reinforcing tube slightly into a reverse funnel shape.

(d) Apply sealing putty (■) to the end of the cable to prevent the hardening agent from flowing in.

(E) Insert the hardening side protection tube (■) and fix it in a predetermined position, and use tape to prevent the hardening agent from leaking on the cable side.

(F) Temporarily fix the hardened coral 3 tube ■ part, hardening agent [phase]
Inject an appropriate amount of the cord, temporarily fix it with a centering tool 0 so that the cord digit 1 is located at the center of the protective tube 2, solidify it, and then attach the optical connector 2.

As described above, the processing method according to the present invention does not require the acquisition of advanced splicing techniques using special equipment, and it is possible to reliably process the end of an optical fiber cable using an easy method.
