[0002] At present, radio frequency is generally used in 2G and 3G base stations in my country. The transmitter transmits the signal to the antenna on the top of the base station through the radio frequency cable. Due to the attenuation of the radio frequency cable, the signal is weakened when the signal reaches the antenna, resulting in the reduction of the coverage of the base station, and A large amount of copper is used in RF cables, which is very expensive

Embodiment Construction
[0012] Such as figure 1 As shown, the 13-core photoelectric composite communication early warning cable for 4G mobile communication (GYTZA-1G6+8P8+1F12+3A type), including power line 1, alarm line 2, ground line 3, filling rope 4, multi-core optical cable 5, tear Crack rope 6, shielding layer 7, sheath 8, eight power lines 1, three alarm lines 2, one ground line 3, several filling ropes 4, one multi-core optical cable 7 twisted into a bundle, and wrapped around it A layer of shielding layer 7, a tearing rope 6 is vertically placed outside the shielding layer 7, and then a layer of sheath 8 is extruded as a whole to form a photoelectric composite cable. The shielding layer 8 is in contact with the ground wire 3 exposed outside the cabling after being twisted into a bundle to form a ground wire together.
[0013] The cable can determine the number of optical fibers according to the method used by the antenna, and then combine the overall system plan to determine the specificati...

The invention relates to a 13-core photoelectric composite communication early-warning cable for 4G mobile communication, which comprises power lines, alarm lines, an earth wire, fillers, a multicore cable, a rip cord, a shielding layer and a sheath, wherein eight power lines, three alarm lines, one earth wire, a plurality of fillers and one multicore cable are twisted into a bundle, the bundle is wrapped with a shielding layer, a sheath is extruded outside of the shielding layer, and the rip cord is longitudinally placed between the shielding layer and the sheath; and the shielding layer is contacted with the earth wire which is exposed to the outside of the twisted bundle so as to jointly form a ground lead. The early-warning cable disclosed by the invention has the characteristics that through photoelectric conversion, the multicore cable extends to the top of a tower, thereby significantly reducing an attenuation problem caused by using a radio frequency mode, in such a way, the coverage range of an antenna is larger, and the transmission speed is higher. The radio frequency mode is changed into a remote multicore cable mode, and a copper cable transmission mode is changed into a multicore cable transmission mode, so that the cost is greatly reduced.
Description
technical field [0001] The invention relates to a 13-core optoelectronic composite communication early warning cable for 4G mobile communication. The cable synthesizes several cables used in mobile base stations and is widely used in mobile communication systems, especially in fierce battles of 4G LTE. Background technique [0002] At present, radio frequency is generally used in 2G and 3G base stations in my country. The transmitter transmits the signal to the antenna on the top of the base station through the radio frequency cable. Due to the attenuation of the radio frequency cable, the signal is weakened when the signal reaches the antenna, resulting in the reduction of the coverage of the base station, and A large amount of copper is used in RF cables, which is very expensive. Contents of the invention [0003] In view of the deficiencies in the existing technology, the present invention adopts the technology of multi-core optical cable hauling, and at the same t...
