BBU end can be connected to CWDM coarse wavelength division multiplexer through CWDM color optical module and OS2 single mode optical fiber patch cord, and then transmitted to CWDM coarse wavelength division multiplexer with one or two optical fibers. The operation of base stations requires a large number of optical modules for interconnection between devices, and we will talk about the application of optical modules in mobile communication base stations. Communication base station is composed of machine room, base station, antenna, feeder. The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. The BBU is small and exquisite, with low power consumption, while the RRU is large and has high power consumption. In 4G networks, the optical modules used to connect BBU and RRU are mainly gigabit to 10Gbit optical modules. In modern server racks, the wrong optical choice can silently tax performance: queues grow, link training becomes flaky, and operators end up swapping modules mid-quarter.
