Description

Technical Field

In the fields of integrated wiring, data centers, urban pipeline networks, etc., the use of optical fiber and cable is increasing, and the workload of optical fiber splicing has increased dramatically.

[0003] In document CN201921443268.7, a kind of easy-to-strip high-density full-dry optical cable is proposed, including an outer sheath and a cable core, characterized in that the cable core is a full-dry cable core, including an outer sheath and a cable core, characterized in that the cable core is a full-dry layer-twisted cable core, the cable core includes an easy-to-strip loose tube, non-metallic auxiliary reinforcement elements are arranged between the loose tubes, optical communication units and water-blocking yarns are laid in the loose tubes, water-blocking yarns are laid in the cable core, the cable core is coated with a water-blocking layer, and the outermost layer is an outer sheath. The utility model has a high optical fiber density, meets the needs of high-density networks, improves the utilization rate of laying resources, and has a small diameter and light weight. The diameter of the optical cable is only about 1 / 2 of that of the traditional optical cable, and has excellent mechanical properties, which can be used for pipeline and self-supporting overhead laying; the sheath and loose tube are easy to strip, and the use of continuous connection is convenient, which improves the construction efficiency; the fully heterogeneous structure has the performance of anti-electromagnetic interference and lightning protection.

[0004] The easy-to-strip high-density all-dry optical cable proposed in the above patent can be easily stripped during use, but the protection coefficient of the outer protective sheath is low. The optical cable needs to be laid during use, which causes it to be dragged and rubbed on the road surface. Dragging causes a large friction coefficient between the protective sheath and the ground, and also causes vibration inside the protective sheath, accelerating its wear. In addition, it may be stepped on during the laying process. Both dragging and stepping on it will affect the service life of the optical fiber in the protective sheath and reduce the use effect of the optical cable.
