Problems solved by technology

[0002] The existing central bundle tube type optical cable includes a cable core and an outer sheath covering the outer periphery of the cable core. The cable core includes a loose tube and a plurality of colored optical fibers or tight-sleeved optical fibers arranged in the loose tube. It is called a central bundle tube type optical cable. The fiber paste is filled between the loose tube and the optical fiber to play a waterproof and water-blocking role. However, the fiber paste is used as the water-blocking material. Due to the buffer of the fiber paste, the transmission The sensitivity is not high, which affects the communication quality

Abstract

The invention relates to an optical cable of central beam tube type, comprising a core and an outer guard layer covering the core, wherein the core comprises a loose tube and a plurality of colored optical fibers or tight buffered optical fibers which are provided in the loose tube and axially extended along the loose tube, a waterproof yarn is provided in the loose tube and axially extended along the loose tube. The invention uses the waterproof yarn to replace traditional fiber paste to provide uniform protection for water transfer, make optical fibers attain high sensing sensitivity and make the optical cable attain good beading property, therefore, the optical cable of central beam tube type has wide application.

Description

technical field [0001] The invention relates to a communication optical cable, in particular to a central beam tube sensor optical cable. Background technique [0002] The existing central bundle tube type optical cable includes a cable core and an outer sheath covering the outer periphery of the cable core. The cable core includes a loose tube and a plurality of colored optical fibers or tight-sleeved optical fibers arranged in the loose tube. It is called a central bundle tube type optical cable. The fiber paste is filled between the loose tube and the optical fiber to play a waterproof and water-blocking role. However, the fiber paste is used as the water-blocking material. Due to the buffer of the fiber paste, the transmission The sensitivity is not high, which affects the communication quality. Contents of the invention [0003] The object of the present invention is to provide a sensing optical cable with high sensing sensitivity and better bending performance of th...
