Problems solved by technology

Therefore, the optical cable layout mainly adopts the vertical layout in the vertical shaft and the horizontal layout of the trunking. However, these two wiring methods not only require high mechanical strength of the optical cable, but also have the problems of cumbersome construction, low construction efficiency and high initial investment.

Abstract

The invention discloses a low-friction micro optical cable suitable for air blowing and conduit wiring, and relates to the technical field of communication optical cables. The low-friction micro optical cable comprises a cable core, an internal protective layer and a sheath which are arranged from inside to outside in turn. The internal protective layer wraps outside the cable core. The cable core comprises multiple optical fibers and a reinforcing member. The external surface of the sheath is provided with a low-friction coating layer. The low-friction micro optical cable suitable for air blowing and conduit wiring comprises the cable core composed of the reinforcing member and the optical cables, and the cable core is bound in the internal protective layer so that the cable core is enabled to have certain rigidity; and the external surface of the sheath is coated by a low-friction solution which is heated, cooled and cured at the external surface of the sheath to form the low-friction coating layer so that the surface of the optical cable is enabled to have low friction coefficient, air blowing performance of the optical cable in a pipeline is optimized and conduit wiring of the optical cable can also be performed in the short distance, and thus the construction procedure can be facilitated and simplified and cost and time can be saved.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a low-friction miniature optical cable suitable for air delivery and pipe routing. Background technique [0002] The air-blow laying method of optical cable is to lay the optical cable in the pre-embedded silicon tube by means of high-pressure air blowing. Among them, the main factors affecting the cable blowing effect are: the ratio of the outer diameter of the optical cable to the inner diameter of the plastic pipe, the weight per unit length of the optical cable, and the sheath material. [0003] Existing optical cables are mainly composed of optical fibers, plastic protective sleeves and plastic sheaths. When the optical cables are deployed in buildings or indoors, due to the relatively large surface roughness of the plastic sheaths of the optical cables, and the large outer diameter and weight of the optical cables, it is not suitable for installation. ...
