Detailed Description
Referring to fig. 1 and 2: the utility model relates to a micro-cluster optical cable, the optical cable includes a plurality of little beam tube optical unit, enhancement layer 5, reinforcement 6 and outer jacket 7.
The microbeam tube optical units are twisted in a unidirectional spiral twisting mode with the twisting pitch of 1000-1500 mm. For example, the twisting pitch is 1000mm, 1200mm, 1500mm, etc., and in the present embodiment, the twisting pitch is 1300 mm.
The micro-beam tube light unit mainly comprises an optical fiber micro-beam tube 3, and a plurality of optical fibers 1 (in the embodiment, the number of the optical fibers 1 is 2-24) and optical fiber ointment 2 which are coated in the optical fiber micro-beam tube 3, wherein the enhancement layer 5 is made of a non-metal enhancement material, the enhancement piece 6 is a non-metal enhancement piece 6, and the outer protective layer 7 is made of a polyethylene material or a low-smoke halogen-free polyolefin material. In this embodiment, the optical cable is of an all-dielectric structure (all the optical cables are designed to be of a non-metal structure), and is suitable for being laid in a lightning area with severe conditions or in the same channel. And is light in weight itself.
Further, the non-metal reinforcing material is aramid yarn.
Further, the non-metal reinforcement 6 is a KFRP bar.
Further, the optical fiber micro-beam tube 3 is formed by extrusion molding by using crystalline plastic.
Further, the crystalline plastic is polybutylene terephthalate or polypropylene. The molding effect is better by adopting polybutylene terephthalate or polypropylene.
Further, the optical cable further comprises a water blocking yarn 4, and the water blocking yarn 4 is filled in a twisting gap between the microbeam tube optical unit and the microbeam tube optical unit. So as to play the role of water resistance and water isolation in the optical cable.
In addition, the KFRP rods are two, are the existing mature materials and are rod-shaped. Have a plurality of sections along this KFRP excellent axial direction spiral winding's of KFRP helicla flute on the excellent periphery wall of KFRP, after the extrusion molding, outer jacket 7 can be filled completely multistage helicla flute (preferred, every section the spiral length of helicla flute is 5m ~ 10m, and this helicla flute is the dovetail structure) on the excellent periphery wall of KFRP. Thereby enhancing the stability between the outer sheath 7 and the KFRP rod on the one hand; on the other hand, when the operator uses a micro-cluster cable having a very short length (the length of the micro-cluster cable is less than 50 m), the KFRP rod is prevented from slipping out of the outer sheath 7 of the micro-cluster cable.
Compared with the common layer stranded optical cable, the micro-cluster optical cable has smaller outer diameter and lower cost on the premise of having the same number of optical fibers 1. Meanwhile, the micro-cluster optical cable does not need to be subjected to yarn binding treatment.
In the micro-cluster optical cable, the optical fiber ointment 2 adopted in the optical fiber micro-bundle tube 3 is less in dosage, the micro-cluster optical cable with a semi-dry structure is formed, and the water-blocking yarn 4 (a water-blocking tape can also be adopted, or the water-blocking yarn 4 and the water-blocking tape are used together) is adopted, so that the micro-cluster optical cable is more environment-friendly, and the optical cable which is discarded and used is better treated.
The above detailed description is only for the purpose of illustration, but not for the purpose of limitation. Although the present invention has been described in detail with reference to the specific embodiments thereof, it will be understood by those skilled in the art that: the above-mentioned specific technical solutions can still be modified, or some technical features thereof can be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the present invention in its essence.
