Problems solved by technology

[0002] With the development and construction of 5G communication in my country, especially the ultra-high frequency requirements of 5G technology for wireless communication frequency bands, whether it is updating existing base stations or building new base stations, the demand for equipment is huge, and among these equipment The connection between the optical cables has put forward a lot of demands, especially for the optical fiber, how to improve the construction efficiency is more prominent, while the traditional optical fiber needs to be connected to the equipment one by one, the construction efficiency is low, and the equipment will be installed after the quantity is large. Internal wiring is easy to cross and twist, which also brings great difficulties to later maintenance

Embodiment 1

[0042] Embodiment 1, an easy-to-open flat optical cable, such as figure 1 , the optical fiber in the optical cable of the present invention adopts a new type of 200 μm G657A2 optical fiber, the prepared optical cable has a small outer diameter and a small bending radius, and can be laid at any angle in the equipment, including several optical fibers 3, and several optical fibers 3 are equipped with optical fiber protective sleeves 2. Several optical fiber protective sleeves 2 are arranged side by side and parallel to each other. Each optical fiber protective sleeve 2 is installed in the same subunit outer sheath 1. There are several grooves 4 distributed on the upper and lower surfaces of the subunit outer sheath 1. The grooves 4 are interposed Between the adjacent optical fiber protective sleeves 2 and recessed toward the inner optical fiber 3, the outer sheath of the optical cable of the present invention is flat, and at the same time a certain number of grooves are distribut...

Embodiment 2

[0045] Embodiment 2, a kind of preparation technology of easy to open and strip flat optical cable, such as image 3 , including the following steps: the first step is to put the optical fiber protective sleeve 2 on the pay-off frame 9, and then the optical cable is connected to the molding table 10; the second step is to connect the extruder mold 5 to the head of the extruder 11, The plastic is plastically molded in the extruder 11; in the third step, the extrusion port of the extruder 11 is connected with a slow cooling device 21, a hot water tank 12, a warm water tank 13, a cold water tank 14, and a blow dryer 15 in sequence; Figure 4 , the fourth step is to place the transmission device 17 and the wire take-up machine 16 at the outlet of the blow dryer 15 in sequence. The flat optical cable extruded by this process can be connected to the equipment access point at one time during construction. When entering the point, the outer sheath can be torn off by hand, and the opti...

Abstract

The invention discloses an easy-to-strip flat cable and a preparation process thereof, and relates to the field of cables. The easy-to-strip flat cable comprises a plurality of optical fibers, whereinthe plurality of optical fibers are provided with optical fiber protection sleeves in a penetrating manner; the plurality of optical fiber protection sleeves are arranged side by side in parallel; each optical fiber protection sleeve is provided with a sub-unit outer sheath in a penetrating manner; and a plurality of grooves are distributed in upper and lower surfaces of the sub-unit outer sheaths. During construction, a plurality of sub-units can be placed among equipment at one time, and meanwhile the sub-units can be stripped more rapidly for use, so that the construction efficiency is improved effectively.
