Problems solved by technology

In order to produce more than 12 cores in the existing center-bundle tube optical cable, the optical fibers must be bound with different colors of binding yarn to distinguish them. This puts forward very high requirements for production technology and production equipment, which is generally difficult to achieve.
Applying existing technology to produce 12-core or more center-bundle tube-type optical cables is very easy to cause waste of raw materials and economic losses

Abstract

The invention discloses an improved central tube type optical cable which comprises an optical cable sheath (1). Two or more than two loose tubes (2) in different colors are parallelly arranged in the optical cable sheath (1), optical fibers (3) in different colors are arranged in each loose tube (2), first water-blocking substances (4) are filled in the loose tubes (2) which are longitudinally wrapped by a composite metal belt (5), second water-blocking substances (6) are filled among the loose tubes (2) and the composite metal belt (5), and reinforcers (7) are parallelly arranged in the optical cable sheath (1). The improved central tube type optical cable solves the technical problems during production of central tube type optical cables with more than 12 cores in the prior art, and is simple in structure and convenient to manufacture.

Description

technical field [0001] The invention relates to the field of communication optical cables, in particular to an improved central tube optical cable. Background technique [0002] The central bundle tube type optical cable under the existing technical conditions has a structure that the center is a loose tube, all the optical fibers are located in the loose tube, and the strengthening member and the sheath are located outside the loose tube. The optical cable of this structure is usually less than 12 cores. In order to produce more than 12 cores in the existing center-bundle tube optical cable, the optical fibers must be bound with different colored yarns to distinguish them. This puts forward very high requirements for production technology and production equipment, which is generally difficult to achieve. Applying the prior art to produce the central bundle tube optical cable with more than 12 cores is very easy to cause waste of raw materials and economic loss. Contents ...
