Radio frequency identification remote cable used for base station and manufacturing method thereof

Abstract

The invention discloses a radio frequency identification remote cable used for a base station and a manufacturing method of the cable. The cable comprises a cable jacket, at least one subcable and at least one filling component, wherein the subcables and the filling components are arranged in the cable jacket, the cable jacket is further internally provided with nonmetallic filling yarns, and the outer surface of the cable jacket is provided with a touch identification mark. The manufacturing method comprises the steps of a, production of optical fibers, b, coloring of the optical fibers, c, tight sleeving of the optical fibers, d, formation of subcable jackets, e, formation of the filling components, f, twisting of a cable core, f, coating of the jacket and h, detection and delivery. The surface mark of the radio frequency identification remote cable used for the base station is clear, resistant to wear and falling off, and likely to be distinguished; the hot-shrinkage rate is small on the high-altitude and high-temperature condition, and it is ensured that the cable and the end of a connector are fastened and sealed; the mechanical performance is good, and a good ratproof effect is achieved; the assembly efficiency of the connector in a factory is improved effectively. The manufacturing process is easy to operate, and the production and development investment is low.

Description

technical field [0001] The invention belongs to the technical field of manufacturing optical cables for indoor and outdoor use, and relates to a radio frequency remote optical cable for a base station, a manufacturing method and a processing technology thereof. Background technique [0002] In the base station signal transmission system, from the base band unit BBU (Base Band Unit) to the remote radio unit RRU (Remote Radio Unit), the optical cable that provides signal transmission for the RRU is called a radio remote optical cable. The radio frequency remote optical cable is mainly used in the local remote at the same site, and the length is usually between 100 meters and 300 meters. [0003] With the increasing demand for mobile data services, the network is required to be able to provide high-speed data services and other value-added services based on data applications to a certain extent. The feature of lower traffic price has attracted people's attention. However, the...

Problems solved by technology

The authorization number is CN203054298U, the name is radio frequency remote optical cable for base station, the authorization number is CN201622374U, and the name is wireless radio frequency remote unit optical cable, both adopt circular sheath structure, but do not fully consider the connection between the two ends of the optical cable in the later assembly The easy identification of the internal sub-cables during the device, the lack of full consideration of the easy identification characteristics of the remote optical cable during the construction of existing towers and later maintenance, and the anti-rat measures in the machine room and tower, and the improper manufacturing process of the remote optical cable have caused serious problems. Heat shrinkage (usually when the sheath is made of LSZH material, the heat shrinkage rate of the cable sheath at 85°C is between 2% and 3.5%), resulting in the problem of separation between the connecting device and the cable

At the same time, among the authorized patented products, the remote optical cable with filling components is made of aramid yarn extruded sheath structure. Very good support, so that when the optical cable is stretched and flattened, it is easy to be unevenly stressed due to structural instability, and even fiber breakage occurs
