A skeleton type hybrid optical cable

Abstract

The invention relates to a skeleton-type hybrid optical cable, which includes a skeleton-type cable core and an outer sheath. The skeleton-type cable core includes a skeleton. The optical fiber ribbon is laid in the middle part of the skeleton groove, and the optical fiber is laid in some of the skeleton grooves to form a hybrid optical cable. In the present invention, the optical fiber ribbon and the separated optical fiber are arranged in the skeleton at the same time, and the separated optical fiber or the optical fiber ribbon in the optical cable can be directly used to connect and cooperate with the original laid optical cable and the optical fiber distribution frame when branching is required during construction, thereby avoiding the trouble of stripping the optical fiber ribbon Trouble, flexible and convenient divergence connection, and can reduce the cost of optical cable laying; the present invention adopts the skeleton groove opened in a vertical line, and the indirect bonding optical fiber ribbon and the loose optical fiber are installed in the skeleton groove, so that the optical fiber ribbon is installed in the skeleton type cable core. When entering the groove with the optical fiber, the skeleton is retracted in a straight line without twisting, which greatly simplifies the manufacturing process and equipment of the cable core, and greatly improves the production speed and efficiency of the skeleton optical cable.

Description

technical field [0001] The invention relates to a skeleton type hybrid optical cable used for an optical transmission line of an optical fiber communication network, and belongs to the technical field of optical communication transmission. Background technique [0002] The fiber optic ribbon is usually laid in the skeleton optical cable. The optical fiber ribbon has the characteristics of large fiber capacity and high fusion splicing efficiency. Type optical fiber cables are connected with other types of optical cables or optical distribution frames (ODF frames) that were originally laid. trouble. On the other hand, the cable core of the skeleton optical cable is usually composed of a skeleton and an optical fiber ribbon installed in the skeleton groove. In order to prevent the optical fiber ribbon from being stressed and ensure its bending resistance, most of the skeleton grooves on the skeleton adopt a helical twisted structure, that is, The skeleton groove rotates along...

AI Technical Summary

Problems solved by technology

Therefore, the production equipment, especially the skeleton take-up and release frame, is bulky and heavy, and the rotation speed of the skeleton is limited, which affects the production efficiency of the optical cable. The control of the process of bringing into the groove is relatively difficult, and it is difficult to use 12-24 core optical fiber ribbons to produce optical cables with a larger number of cores
