Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, a dry-type water-blocking and easy-to-peel multi-core micro-bundle tube series optical cable includes a thin-walled micro-tube 1, and at least two colored optical fibers 2 and a water-blocking yarn 3 are arranged in the thin-walled micro-tube 1. The thin-walled micro-tube Pipe 1 is a thermoplastic flame-retardant low-smoke halogen-free polyolefin sheath.

[0014] Such as figure 1 As shown, the colored optical fiber 2 is an optical fiber whose outer surface is coated with color.

[0015] Such as figure 1 As shown, the water-blocking yarn 3 is a fully dry water-blocking yarn with low linear density.

[0016] Such as figure 1 As shown, there are 12 or 32 colored optical fibers 2 .

[0017] Such as figure 1 As shown, the thickness of the thin-walled microtube 1 is 0.15 mm.

[0018] Such as figure 1 As show...

Abstract

The present invention provides a dry-type water-blocking easily-stripped multi-core micro beam pipe series optical cable including thin-walled micro-tubes, wherein the internal portion of each thin-walled micro-tube is provided with at least two colored optical fibers and a water-blocking yarn. The thin-walled micro-tubes are thermoplastics type flame retardant low smoke halogen-free polyolefin sheathes. The beneficial effects of the present invention are that by wrapping the plurality of colored optical fibers with the thermoplastics type flame retardant low smoke halogen-free polyolefin sheathes, the number of cores of an optical fiber is raised.

Description

technical field [0001] The invention relates to optical cables, in particular to a series of dry-type water-blocking and easy-to-peel multi-core micro-bundle tube optical cables. Background technique [0002] Traditional optical cables have low integration and fewer cores, making it difficult to form a series of optical cables. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a dry-type water-blocking and easy-to-stripping multi-core micro-bundle tube series optical cable with a large number of cores. [0004] The invention provides a series of dry-type water-blocking and easy-to-peel multi-core micro-bundle tube optical cables, including thin-walled micro-tubes, at least two colored optical fibers and a water-blocking yarn are arranged inside the thin-walled micro-tubes, and the thin-walled micro-tubes are thermoplastic Type flame retardant low-smoke halogen-free polyolefin sheath. [0005] As a further improveme...
