Description

Optical cable

The application is a divisional application with the application date of 2016, 04, 14, application number of 201610231010.5 and the name of 'optical cable'.

Technical Field

The invention relates to the field of optical fiber communication, in particular to an optical cable.

Background

The skeletal optical cable comprises: the optical fiber ribbon cable comprises a reinforcing piece, a framework with a mounting groove, an optical fiber ribbon positioned in the mounting groove, a water blocking wrapping tape wrapping the framework and an outer sheath wrapping the water blocking wrapping tape. For identification, the distinction is usually made by providing a marking line or an extruded rib mark.

The marking lines fade slowly along with the lapse of time, which brings great inconvenience to the subsequent maintenance; because the rib mark is a narrow strip extruded together with the framework, the phenomenon of intermittence often occurs, and poor extrusion of the framework is easily caused.

The skeleton type optical cable has the greatest advantage of easy branching, and optical fibers or optical fiber ribbons can be branched to the greatest extent without damaging the optical cable. However, during construction, due to the outer sheath on the outer side of the framework, in order to achieve the purpose of branching, constructors can only peel at least a whole circle of the sheath to achieve the purpose of identifying the needed optical fiber ribbon, and then peel the framework groove to achieve branching of the optical fiber or the optical cable, so that the overall structure of the optical cable is damaged, and the channel which does not need to be damaged is also peeled.

the glue conveying main pipe is communicated with one end of each glue conveying branch pipe penetrating out of the brush body.

During actual use, the glue conveying main pipe is connected with the glue box through the glue pump, and the glue conveying main pipe inputs the adhesive into the brush bristles through the glue conveying branch pipes, so that the brush bristles continuously coat the grooves.

Optionally, the groove includes a bottom wall and inclined side walls located at two sides of the bottom wall, and the bristles extend into the groove and contact with the bottom wall and the inclined side walls of the groove.

This kind of structural style can prevent that the sticker from coating in the recess outside, can guarantee the clean and tidy of overlay non-recess department.
