Embodiment Construction

[0017] To manufacture the optical cable of the present invention, two schemes can be adopted: 1. Refit the existing tight-sleeve optical fiber extrusion production line to precisely control the relative position of the reinforcing yarn and the optical fiber; 2. Refit the optical fiber doubling machine or coloring machine to precisely control The location of the optical fibers and reinforcing yarns.

[0018] The optical cable structure of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0019] figure 1 Shown is a specific embodiment of the invention.

[0020] see figure 1 , figure 1 The inner core of the optical cable shown is a bend-insensitive optical fiber, and the optical fiber is covered with 2-12 strands of reinforcing yarn (depending on the linear density of the reinforcing yarn). The reinforcing yarn needs to be soaked with polyester material, and then coated with polyester Ester material (cured by water coo...

Abstract

The invention relates to a superfine, super anti-bending and superhigh-intensity guidance optical cable. A bending insensitive optical fiber is adopted in an inner core of the optical cable, a reinforced yarn layer is clad on the optical fiber, and an outer cladding is clad on the reinforced yarn layer; the outside diameter of the optical cable is 0.25mm-0.45mm, the tensile force is 8kg-15kg, the allowable minimum bend radius is 5mm, and the operating environment is minus 60 to 85 DEG C. The space occupation ratio of the optical cable can be effectively reduced and the use limitations are reduced by adopting the optical cable; furthermore, the optical cable has the advantages of superfine outside diameter, superhigh intensity, excellent anti-bending property, long length and the like.

Description

technical field [0001] The invention relates to the technology of an ultra-high-strength ultra-thin and ultra-long wired guided optical cable, in particular to an ultra-thin ultra-bending-resistant ultra-high-strength guided optical cable. Background technique [0002] Generally, the indoor flexible optical cable used for access network has an outer diameter of more than 2mm, which causes a certain space ratio and has certain limitations in use. At present, the special optical cable with the smallest outer diameter should be EPFU (Enhanced Optical Fiber Unit). Due to the limitation of tensile strength, this optical cable can only be used under a specific laying method (generally air-blow laying). [0003] The present invention is developed in response to the urgent needs of the field of wired guidance, and has ultra-fine outer diameter (0.25mm-0.45mm), ultra-high tensile strength (8kg-15kg) and excellent bending resistance (allowing the minimum bending radius) 5mm), large l...
