Abstract
The invention relates to a novel optical cable for optical fiber bundle communication. The novel optical cable comprises a cable core and a jacket coated outside the cable core, wherein the cable core comprises a loose casing, multiple strands of optical fiber bundle units which are axially arranged inside the loose casing and fillers which are filled between each strand of optical fiber bundle unit and the loose casing; and the jacket comprises a cable core filling layer which has water resistance and is coated outside the loose casing and a jacket layer coated outside the cable filling layer. Investment on extra equipment is not required for the manufacturing of the optical cable (investment on an optical fiber ribbon combiner and secondary large plastic shield equipment is reduced), and a qualified product can be produced by only slightly improving an ordinary secondary plastic shield production line. Due to the adoption of the optical cable for optical fiber bundle communication, the defects of low density of an optical fiber in the conventional single tube and large outer diameter of a strip-shaped bundle tube are overcome, and full utilization of limited urban duct resources is effectively improved; and moreover, the optical cable has the advantages of mature production process, no need of extra investment and the like, and can be greatly popularized and applied.

Summary of the invention
of the present invention to be provided the novel fiber bundle communication that a kind of caliber is little, density of optic fibre is big and uses optical cable.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Optical cable is used in
a kind of novel fiber bundle communication; Comprise cable core and the sheath that is coated on the outside of described cable core; Described cable core comprise loose sleeve pipe, vertically extend be arranged on the multiply optical fiber bundle unit of described loose inside pipe casing and be filled in the described optical fiber bundle unit of each strand with described loose sleeve pipe between filling material, described sheath comprises the cable core packed layer with block-water performance that is coated on described loose jacket exterior, the restrictive coating that is coated on this described cable core packed layer outside.
preferably are equipped with composite steel-plastic belt, the wall thickness>=2.0mm of described composite steel-plastic belt between described restrictive coating and the described cable core packed layer.
preferably are embedded with two reinforcements that are symmetrically distributed along the axial line of this optical cable in the layer wall of described restrictive coating vertically.
preferably, the wall thickness of described restrictive coating is 3.0mm, the outer wall of described reinforcement is to the bee-line>=1.0mm of the outer wall of described restrictive coating.
preferably, described cable core packed layer is greasy for preventing water, waterstop or water blocking yarn.
preferably, described filling material is fine cream, water blocking yarn or water-proofing powder.
preferably, described restrictive coating is processed by polythene material or low-smoke non-halogen flame-retardant material.
preferably, described loose sleeve pipe is processed by the PBT material, the wall thickness of described loose sleeve pipe is 0.55mm.
preferably, described optical fiber bundle unit is tied up by the outside yarn that twines different colours of 2-12 root silica fibre and is formed.
preferably, the number of share of stock scope of the described optical fiber bundle unit in the described cable core is: 8-24.
the invention has the beneficial effects as follows: the input (reduced optical fiber and band machine and the big cover of secondary is moulded the equipment input) that does not need extras; Only need common secondary coating production line just to improve a little and can produce qualified product; This fibre bundle communication has remedied the not high and ribbon beam external diameter of pipe shortcoming bigger than normal of traditional single tube inner fiber density with optical cable; Improved making full use of of urban duct limited resources effectively; And mature production technology need not advantages such as extra input, can widely popularize utilization.
