Problems solved by technology

This type of optical cable of the prior art mainly has the following defects: one is: the marking line will slowly fade as time goes on, so it brings great inconvenience to future maintenance; and the making of the marking line itself Relatively troublesome; the second is: when the rib label is used, because the rib label is a narrow strip extruded together with the skeleton, there will often be intermittent phenomena, which will easily lead to poor extrusion of the skeleton; the third is: skeleton optical cable The biggest advantage is that it is easy to branch, and it can complete the

Abstract

The invention relates to the technical field of optical transmission communication carriers, in particular to an easy-to-strip skeleton type optical cable, which comprises a central reinforcing piece (1) positioned at the center, a skeleton (3) consisting of a cylinder with skeleton grooves (2), optical fibers (4) or optical fiber belts positioned in the skeleton grooves (2), a belting layer (6) covering the skeleton (3) and the skeleton grooves (2), and an outer protective layer (7) extruding outside the belting layer, and is characterized in that a marking belt (5) is arranged in at least one skeleton groove (2) in the optical cable and can be conductive or magnetic, and the central reinforcing piece is non-metallic. The invention has the following beneficial effects of faster production speed of the optical cable, more convenient maintenance, simpler identification and longer service life of optical fibers.

Description

technical field [0001] The invention relates to the technical field of optical transmission and communication carriers, and is an improvement to the existing skeleton optical cable, in particular to an easy-to-stripping skeleton optical cable. Background technique [0002] The Communication Industry Standard of the People's Republic of China YD / T981.1-2009 "Optical Fiber Ribbon Cables for Access Network Part 1: Skeleton Type" stipulates a variety of skeleton type optical cables; The optical fiber ribbon, the tape covering the skeleton, and the outer sheath outside the tape; in addition, in order to facilitate identification, marking lines or extruded ribs are usually used to distinguish them. This type of optical cable of the prior art mainly has the following defects: one is: the marking line will slowly fade as time goes on, so it brings great inconvenience to future maintenance; and the making of the marking line itself Relatively troublesome; the second is: when the rib...
