Optical fiber multiplexing equipment essentially uses 8 to 16 wavelengths of coarse wavelength division to perform wavelength division multiplexing to synthesize optical signals of different wavelengths into a beam of light, which is then decomposed at the receiving end, thereby achieving single fiber multiplexing. Wave division. The new types of optical fiber multiplexing equipment products mainly include 1:6 polymerization, 1:8 polymerization, 1:12 polymerization and 1:18 polymerization. The wavelength is between 1271nm and 1611nm, and the number of channels that can be synthesized or separated are: 6, 8, 12, and 18. The maximum transmission capacity is up to 80Gbit/s and supports multiple network frequency bands such as 2G, 3G, 4G and 5G. Compared with the old wavelength division multiplexing equipment, this new type of optical fiber multiplexing equipment is more technologically advanced, and the appearance, quality, shape and other aspects of the equipment have become more refined, which can be applied to various network construction environments, so that Multi-channel deployment can alleviate the lack of fiber core caused by large-scale station construction in a timely manner.
The application of optical fiber multiplexing equipment in 4G networks is becoming more and more mature. In the complex 5G network construction scenario, it is also possible to implement rapid optical cable reconstruction by applying optical fiber multiplexing equipment, using a pair or one optical fiber to achieve multiple AAU to The connection between BBU (CU+DU) achieves the purpose of quickly building a 5G network. Application scenarios: 5G network construction for subway tunnels, 5G access network construction based on C-RAN, 5G construction for indoor distribution systems, and 5G coverage such as high-speed railways.
At present, 5G network construction is in the stage of technical verification and trial network construction, but with the customer's demand for the network, large-scale and large-scale 5G network construction is getting closer and closer to us.
