In modern mobile networks, fronthaul is the segment of the network linking centralized baseband units (BBUs) to remote radio units (RRUs) or active antenna units (AAUs) at the edge of the network . Optical module fronthaul uses fiber-optic technology to transmit data efficiently over these links, supporting high bandwidth and low latency requirements essential for 5G and beyond .
Optical modules in fronthaul can be categorized based on their transmission method:
Next-generation fronthaul optical modules are being developed to meet 6G requirements, including higher bandwidth, longer fiber reach, and improved optical link quality. Innovations include semi-active and active WDM solutions and enhanced modulation formats like PAM4 to increase data rates while maintaining signal integrity .
Optical module fronthaul is a critical enabler for high-performance mobile networks, providing the optical interface and modules that connect BBUs to RRUs. By leveraging technologies like DWDM, BIDI, and advanced SFP modules, it maximizes fiber efficiency, supports high data rates, and ensures low-latency transmission, making it essential for 5G and future 6G deployments .
