Abstract

The invention belongs to the technical field of communication optical cables, and relates to an elastic butterfly optical cable. According to the structural design of the optical cable, an elastic outer sheath column body with a rhombic outer sheath cross section is adopted; two reinforcing part units and four optical fiber units are arranged in parallel in the outer sheath and are symmetrically distributed on two diagonals of the rhombic cross section of the outer sheath; and two component force grooves pointing to optical fiber units are arranged in each side surface of the rhombic elastic outer sheath column body. The optical fiber unit comprises a fastening layer of a super-strong ultralow-loss bending insensitive optical fiber and a nylon material, a reinforcing unit with a reinforcing part with high flexibility and a reinforcing part cushion layer of the honeycomb-shaped structure, and an outer sheath of a low-smoke halogen-free flame-retardant TPU sheath material. The elastic butterfly optical cable has the performances of large transmission amount, softness, bending resistance, tensile resistance and compression resistance, and can meet the performance requirements of goodwear resistance, oil contamination resistance, cold resistance, high elasticity and the like. The cable is used as a leading-in optical cable, and is suitable for being laid in a street, a community and a building pipeline in cities.

Description

technical field [0001] The invention belongs to the technical field of communication optical cables, in particular to an elastic butterfly optical cable. Background technique [0002] With the continuous development of social economy, the construction of optical fiber network has been accelerated in recent years, and the collection volume of butterfly optical cable has reached a new high almost every year. Compared with copper lead-in cables, butterfly-shaped lead-in cables are light in weight and can bring convenience to construction. However, due to the small diameter of the optical fiber and poor toughness, the butterfly-shaped cable will have serious deformation after being stretched and dragged. , the resilience of the cable is poor. Therefore, there is a need for a butterfly optical cable with good properties such as wear resistance, oil resistance, cold resistance, and high elasticity. Contents of the invention [0003] The object of the present invention is to pr...
