Feeder terminal
Feeder terminal is a kind of terminal equipment with copper wire as the transmission medium, which is mainly composed of copper strip, copper wire, shielded cable and optical cable. It can be mobile communication base station terminal equipment, also can be indoor signal transmission terminal equipment. In order to facilitate the application, the "outdoor terminal" is called "feeder terminal", because the "outdoor terminal" can transmit signals through various media, including optical fiber transmission, coaxial cable and all kinds of optical fiber and cable. Feeder terminals can be transmitted indoors through optical fiber and coaxial cable.
1. Communication equipment
At present, feeder terminals are mainly used for the transmission of mobile communication base stations and indoor signals to achieve signal coverage in buildings and provide services for urban residents, which is an important infrastructure to achieve full coverage of mobile communication network. Compared with the base station, the transmission medium of the feeder terminal is smaller copper strip wire, which has high transmission rate, good signal quality and low loss. Feeder terminals are usually placed in fixed positions to meet the requirements of various environments, including temperature, humidity, and dust resistance. It mainly includes outdoor antenna radiation cooling system and optical fiber interface. The outdoor antenna is one of the main receiving devices of the communication base station, which is of great significance to the communication. In the field communication, the antenna is a relatively important one, because the antenna reflects the radio waves out through the antenna, and the power of the antenna is the largest in the whole range. It gathers the electromagnetic waves together to form a reflection field and scattering field. Eventually it creates a magnetic field that spreads around the object. In order to ensure the receiving of a strong enough signal and effectively avoid electromagnetic wave impact on the equipment.

2. Equipment Room
The machine room is a special communication environment, which usually needs to cover the communication base station, so the communication signals need to be evenly transmitted to each machine room. In this process, in addition to the signals of the receiving end, there are also transmission links and indoor optical cable and other related equipment for communication signal transmission. Without this process, the telecom operators can not complete the base station communication guarantee. If the communication base station is outside, the network will be blocked, and the signal cannot be transmitted normally when it is transmitted outside. If the mobile communication base station is blocked by the machine room, it will cause the decline of communication quality and service quality, thus affecting the construction of the base station.
3. Environmental conditions
Generally, the operating environment of a feeder terminal requires a temperature of -40 ° C to +80 ° C and a relative humidity of 80% to 90%. If the temperature is higher than that, the metal conductivity and cable insulation performance will decrease, and the current will easily leak out. If the temperature rises, the insulation layer will be damaged, the current will increase, and communication faults will occur. Therefore, environmental factors and operating conditions should be considered when choosing feeder terminals. To ensure the normal operation of the device, keep the temperature above 40 ° C. An excessively high temperature may damage the feeder terminal. Electromagnetic radiation should also be considered. Due to the long service life of outdoor communication base stations, many factors should be considered in the selection of materials. For the feeder terminal, the first is the performance requirements, and outdoor construction should be carried out after the indoor cable laying of the base station is completed. If the outdoor environment temperature is too high or too low) will have a bad impact on the cable will affect the performance of the equipment or even damage the equipment.
