Color bar identification skylight construction optical cable and production method

Abstract

The invention discloses a color bar identification skylight construction optical cable and a production method. Optical fibers are inserted in loose tubes; a plurality of loose tubes are stranded mutually and form a cable core; an outer sheath is coated on the cable core; the cable core comprises a forward stranded part and a reverse stranded part; both the forward stranded part and the reverse stranded part of the cable core are coated with fixed bands; an identification block is attached to a position of a forward and reverse reversing point of the cable core; a color ribbon is arranged on the side wall of the outer sheath; the color ribbon is arranged along the axial direction of the outer sheath; a twisting point is arranged on the color ribbon; and the position of the twisting point corresponds to the positions of the identification blocks. According to the invention, an optical cable construction continuing operator can rapidly identify the position of the position of the SZ stranding reversing point of the cable core inside the optical cable by pattern features of a color bar outside the optical cable so as to carry out targeted stripping construction work, thereby greatly reducing workload of skylight construction of the optical cable, improving construction efficiency and saving labor cost of optical cable construction.

Description

Technical field: [0001] The invention relates to a construction optical cable for skylight opening with color stripe identification and a production method thereof. Background technique: [0002] Optical cable "open skylight" construction and connection work is required when the optical cable is in the branch transition, fast fault location and maintenance. However, in the construction of the traditional layer-stranded optical cable skylight, it is necessary to strip the optical cable for a long distance, find the most suitable and closest one or more than one starting position of the cable core SZ twisting and reversing point to strip the optical cable, and solve the problem. Open the inner loose tube optical fiber unit, and carry out the construction splicing work. However, in actual construction, it is impossible to accurately locate the position of the SZ twisting and reversing point of the optical cable, so it is necessary to increase the stripping length of the optica...

Problems solved by technology

However, in the actual construction, it is impossible to accurately locate the position of the SZ twisting and reversing point of the optical cable, so it is necessary to increase the stripping length of the optical cable, which greatly affects the construction efficiency, and is also not conducive to the later maintenance of the optical cable line.
