The communication base station is composed of computer rooms, base stations, antennas, feeders (transmission lines between launch and antenna) and supporting equipment. At the top of the signal tower, an antenna is a computer room under the tower. The base station is placed in the machine room. The base station is a device that sends wireless signals. The base station is divided into two parts: BBU and RRU. The sending and receiving lines are used to connect antenna and base stations. The supporting devices include power and constant temperature equipment to ensure that the base station can run normally under extreme weather.
General base stations will run BBU and RRU separately. BBUs are placed in the computer room, and RRU is placed on the tower. It is used to connect the BBU and RRU devices as the optical module and optical fiber. In the 4G network, the optical module connected to the BBU and RRU connection It is mainly a light to 10,000 gigabit light modules. In the 5G network, the light module used for BBU and RRU connections is mainly 25G rates.
Let me talk about the 1.25G SFP light module for connecting the BBU and RRU devices and the 10G SFP+light module
① 1.25G SFP light module (Gigabit Light Module)
With a wavelength of 850nm, the working temperature is 0-75 ° C, the power consumption is less than 1W, and the transmission distance is 550m through multi-mode fiber;
② 10G SFP+Light Module (Mallless Light Module)
The wavelength of 850nm is used, the operating temperature is 0-75 ° C, the power consumption is less than 1W, and the transmission distance is 300m through multi-mode fiber.
With the arrival of the 5G era, 5G allows the network and life to better combine or even extend new products. Therefore, we can know that the next era must be the world of 5G. 5G is not only a speed but also an interconnection in all aspects. After opening this road, the era of big data entered a brand new world.
