When using the system, the optical modules of standard wavelengths (commonly used 1550nm or 1310nm) of BBU/DU or RRU/AAU (commonly known as gray light module or white light module) need to be replaced with color optical modules of the same rate. The transmission carriers connecting BBU and RRU devices are optical modules and optical fibers. Currently, 5G of the bearer network mainly uses 25Gbps optical. Passive WDM uses WDM technology to combine the circuits from BBU/DU to different RRU/AAU using different wavelengths into a single fiber for transmission. For example, a macro station has 3 RRUs in a certain band of S111 stations and 6 transceiver ports from BBU to RRU, a 6-way OTM (optical. When engineers search for “SFP wavelength,” they are typically trying to answer a practical deployment question: Which optical wavelength should I use—850 nm, 1310 nm, or 1550 nm—and why does it matter? The answer directly affects fiber compatibility, transmission distance, link stability, and. AAU, RRU, and BBU are key components in a telecom network, particularly in modern wireless communication systems like 4G and 5G. Here's a breakdown of each: The central processing unit in a base station. 25G SFP optical module adopts the wavelength of 850nm, with an operating. In modern fiber-optical networks, a 1550nm optical transceiver plays a vital role by converting electrical data into invisible light, sending it across single-mode fibers over long distances, and then restoring it back into electrical form.
