Description

Urban rail transit 5G antenna optical cable installation auxiliary device that colds pressing
Technical Field
The invention relates to the technical field of cold-pressing installation of optical cables, in particular to an auxiliary cold-pressing installation device for an optical cable of an urban rail transit 5G antenna.
Background
In recent years, the fifth generation mobile communication system 5G is becoming a hot spot for discussion in the communication industry and academia. The rapid development of 5G from the current development has two main driving forces. On the one hand, the fourth generation mobile communication system 4G of long term evolution is fully commercially available, and the schedule is pushed to the more advanced research; on the other hand, in response to the explosive growth of the demands of mobile data users, it is feared that it is difficult to satisfy the demands in the future according to the existing mobile communication system, and the development of a new generation 5G system is urgently required in view of the current situation.
The main advantage of 5G networks is that the data transfer rate is much higher than previous 4G networks, up to 10Gbit/s, faster than current wired internet, 100 times faster than previous 4G te cellular networks. Another advantage is a lower network delay (faster response time), below 1 ms, and a 4G of 30-70 ms. As data transmission is faster, 5G networks will not only serve handsets, but will also become generic home and office network providers, competing with wired network providers. The domestic communication of the rail transit in Hehaote city is realized, the national subway industry firstly uses the 5G network as a 5G network test point area, and the method has profound significance for the development of the rail transit 5G and the indoor 5G (such as office buildings, commercial squares and the like).
The first 5G antenna of the subway 1 line of the Haote city is installed and applied in the domestic subway, according to field investigation, the 5G is different from the 4G, the indoor leaky cable is required to be changed into the optical cable to meet the data magnitude transmission rate requirement, a welding machine is required to be used in the traditional general hot melting mode, the hot melting defect is that the instrument is high in price, continuous power consumption is required, the maintenance cost is high, the welding cost of professional welding personnel is high, and the operation field is limited. Particularly, the civil antenna has a plurality of terminal points, needs to be constructed on the suspended ceiling after finishing the suspended ceiling, has limited battery endurance, is inconvenient to place by an electricity taking and welding machine, is unfavorable for site construction and has higher cost, so that the 5G antenna in Haoyue is connected by adopting an optical fiber cold connection mode, an LC connector of a cold-pressed terminal is used, and an optical fiber is connected with the LC connector by adopting a V-shaped wedge. I invest in professional technicians, conduct training and learning on the 5G technology through supervising personnel of a mobile company, select a template station, a western-style second-round station and a post-tower-free gas station, and conduct equipment and antenna installation construction. I count the antenna installation condition, and the on-site line rate is relatively poor, leads to the antenna line rate to be only 82.68%, improves the antenna qualification rate, reduces the key of reworking in the construction process.
Aiming at the problem of lower antenna loading rate, the problem is thoroughly discussed and refined by a subject team through careful field comparison analysis, and the three problems of uneven protection sleeve at the root of the optical fiber, clearance of the optical fiber clamp cover optical fiber and bare fiber exceeding the window of the LC connector are found to be the main reasons for influencing the one-time qualification rate of the installation and debugging of the 5G indoor antenna.
