News summary: Adtran today launched the industry's first full C-band tunable 50Gbit/s SFP56 DWDM PAM4 pluggable transceiver, the AccessWave50™, to enhance mobile network operators’ 5G fronthaul capacity while reducing operational costs and energy consumption. By replacing two 25Gbit/s units with a single 50Gbit/s transceiver, it cuts power usage to less than 3W and simplifies deployments through features like zero-touch provisioning and auto-tuning. A live demonstration at OFC 2025 will exhibit its capabilities, addressing growing bandwidth needs at the mobile network edge.
