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.

The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. An. Which optical modules are commonly used in 4G base stations? In this blog, ETU-LINK will talk about 4G base stations and common types of optical modules. • Wear ESD wrist strap or ESD gloves to prevent electrostatic damage to the subrack. • Only when the BBU install in TP48200A and APM30H cabinets, subrack cable claws are configured. 25G SFP optical module adopts the wavelength of 850nm, with an operating.
