Embodiment Construction
[0050] The present invention will be described in detail below in conjunction with the drawings.
[0051] Such as image 3 with 5 As shown, a method for manufacturing an optical cable includes the following steps:
[0052] 1) Process the frame 1 with a plurality of installation grooves 3 on the outer side wall, and embed the reinforcement 4 in the hollow of the frame 1;
[0053] 2) Place the optical fiber unit 5 in the corresponding installation slot 3;
[0054] 3) Cover the cover plate 6 on the open end of the installation slot 3;
[0055] 4) Outsourcing the water blocking band 7 on the outside of the frame 1 and the cover 6;
[0056] 5) A sheath 8 with a positioning structure 9 is formed on the outside of the water-blocking band 7 by an extruder. The outer side wall of the sheath 8 has N sets of positioning structures 9, and the positioning structures 9 are matched with the installation grooves 3 one by one. Each set of positioning structures 9 includes two positioning grooves 10, and...

The invention discloses a manufacturing method of an optical cable. The manufacturing method comprises the following steps of 1) processing a framework of which an outer side wall is provided with a plurality of mounting grooves, and embedding a reinforcer into a hollow part of the framework; 2) placing optical fiber units in the corresponding mounting grooves; 3) covering a cover plate at an opening end of the mounting groove; 4) wrapping outer sides of the framework and the cover plate with a water-blocking wrapping tape; 5) forming a sheath with a positioning structure on an outer side of the water-blocking wrapping tape through a plastic extruding machine, n groups of positioning structures being arranged on an outer side wall of the sheath, the positioning structures being matched with the mounting grooves in a one-to-one correspondence mode, each group of positioning structures comprising two positioning grooves, the two positioning grooves of each positioning structure corresponding to two sides of the corresponding mounting groove respectively, at least N-1 groups of positioning structures comprising recognition grooves, and the number of the recognition grooves of each positioning structure being different, and 6) cooling and drying the sheath, and rolling to obtain the optical cable. The method is advantaged in that an optical cable produced by the method can quicklydetermine the specific positions of different mounting grooves.
Description
Technical field [0001] The invention relates to the field of optical fiber communication, in particular to a method for manufacturing an optical cable. Background technique [0002] The skeleton type optical cable includes: a skeleton with an installation groove, an optical fiber ribbon in the installation groove, a waterproof bag covering the skeleton, and a sheath located outside the bag. In order to facilitate identification and realize the quick opening of the corresponding installation slot, the identification is usually achieved by setting a marking line, and in addition, the identification is carried out by matching the magnetic powder and the detection device. [0003] The former marking line will gradually fade over time, causing inconvenience to future maintenance; the latter is more costly. [0004] In addition, during the stripping operation of the existing optical cable, the operation is cumbersome and difficult to operate, and the operator is easily cut by the cutter. ...
