Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber repeaters, and specifically relates to a remote unit of an optical fiber repeater. Background Art

[0002] An optical fiber repeater is a repeater that transmits signals through optical fibers. By taking advantage of the characteristics of small optical fiber transmission loss, convenient wiring, and suitability for long-distance transmission, it can solve the problems of villages, tourist areas, highways, etc. where base station signals cannot be received, and can also solve the signal coverage within large and extra-large buildings. It is used in large high-rise area buildings (groups), communities, etc. with high requirements. The number of users is constantly increasing, so that the cell planning is getting smaller and the base station location is getting lower. On the other hand, with the high-rise development of urban construction, high-rise buildings are constantly emerging. Due to the shadow effect of wireless propagation, blind or weak areas of mobile communication signals often form behind or in the middle of these high-rise buildings. In addition, during the construction of cellular mobile base stations, due to considering the interference problem of adjacent cells, the main lobe of the antenna radiation pattern has a large downward tilt angle, so that the upper and middle parts of high-rise buildings generally cannot effectively receive signals. Moreover, due to the shielding effect of buildings and the like on electromagnetic waves, mobile communication signals cannot be normally received in some enclosed large buildings such as tunnels, subways, underground shopping malls, entertainment cities, parking lots, hotels, and office buildings. A repeater is a relay repeater between a base station and a mobile station, belonging to a co-frequency amplification device, which refers to a radio transmitting and relaying device that enhances signals during the wireless communication transmission process. The basic function of a repeater is a radio frequency signal power enhancer. Using a repeater as one of the necessary means to achieve the goal of "small capacity, large coverage" is mainly because, on the one hand, it can ensure network coverage without increasing the number of base stations, and on the other hand, its cost is much lower than that of a microcellular system with the same effect.

[0003] According to a patent number CN209072497U published on the China Patent Network, a fiber optic repeater remote device includes a remote device body, a fixed heat sink and a movable heat sink. A pair of mounting sleeves are provided on the top of the remote device body, and a telescopic handle is connected to the same end of the pair of mounting sleeves. A pair of universal rollers are provided on the side opposite to the telescopic handle of the remote device body. A plurality of fixed heat sinks are arranged, and the plurality of fixed heat sinks are evenly arranged in a row at the bottom of the remote device body. A plurality of movable heat sinks are provided. The utility model adopts a fixed heat sink on the remote device body. The combined design of the plate and the movable heat sink allows the device to be installed with the movable heat sink facing outward during installation. This not only makes the heat dissipation efficiency of the device higher, but also allows the inclination angle of the heat sink body on the movable heat sink to be adjusted according to actual conditions, so that rainwater can be quickly drained when it rains, thereby preventing rainwater from being retained for a long time and causing corrosion to the surface of the device. However, the remote machine of the optical fiber repeater station does not have a protective component. When the remote machine is in use, external objects can collide with the remote machine casing, resulting in poor safety of use. In addition, rainwater can also corrode the casing of the remote machine in rainy weather, reducing the service life of the remote machine.

[0004] Therefore, it is necessary to redesign the remote unit of the optical fiber repeater station to effectively prevent the phenomenon that it is difficult to protect. Summary of the invention
