Optical module rate of the main control board used in 4G sites

Optical module rate of the main control board used in 4G sites

The optical modules used in the main control board (BBU) of 4G base stations typically operate at 1.25G, 2.5G, 6G, or 10G data rates.In 4G networks, the base station is divided into the BBU (Baseband Unit) and RRU (Remote Radio Unit). The BBU handles signal processing and is connected to the RRU via optical fiber using optical modules. The data rate of these optical modules depends on network requirements, distance, and fiber availability. Commonly, 1.25G and 2.5G modules are used for standard fronthaul connections, while 6G and 10G modules are deployed for higher-capacity links or longer distances to support multiple RRUs from a single BBU .Optical Module Function and Main Control Board RoleThe optical module contains a Transmitter Optical Sub-Assembly (TOSA) and a Receiver Optical Sub-Assembly (ROSA), along with a main control PCB that manages signal conversion and transmission. The main control board ensures electrical-to-optical signal conversion, clock recovery, and maintains signal integrity at the specified data rate . High-speed modules require precise PCB design, often using advanced materials and HDI technology to support low-latency, high-frequency signals .Deployment ConsiderationsFronthaul capacity: The number of optical fibers and module data rate determine the total throughput between BBU and RRU. Typically, 2–6 fibers are used per RRU, sometimes combined with CWDM (Coarse Wavelength Division Multiplexing) to maximize fiber utilization .Latency and reliability: Low-latency optical modules are critical for real-time 4G services. Modules often include analog clock-and-data recovery (CDR) chips to maintain signal timing .Environmental factors: Outdoor RRUs require modules with hermetic or I-temp packaging to withstand temperature, moisture, and dust variations . In summary, 4G BBU optical modules operate primarily at 1.25G, 2.5G, 6G, or 10G, with the main control board ensuring proper signal conversion and integrity. Selection depends on network capacity, fiber availability, and environmental conditions.
