Wireless Transceiver Now in Full Production for 10 km, 15 km BiDi and WDM Links

Semtech Corporation (Nasdaq: SMTC), a leading provider of high-performance semiconductors powering AI data center networking and intelligent, connected Internet of Things (“IoT”) devices worldwide, today announced full production availability of its mobile transport portfolio enabling 50G fronthaul for the next wave of 5G-Advanced radio deployments. The announcement aligns with the industry’s transition to 50G optical interfaces, marked by Ericsson’s Mobile World Congress 2026-announced portfolio of AI-ready Massive Multiple-Input Multiple-Output (MIMO) and remote radios, and Nokia’s Doksuri Remote Radio Heads built on the latest ReefShark System on Chip (SoC) — each engineered to handle the surge in uplink traffic driven by multi-modal AI, augmented reality, and generative AI applications on mobile devices.

Now shipping in volume, Semtech’s mobile transport portfolio enables system vendors and operators to deploy the fronthaul architecture required by many of today's radio platforms.

Cloud-assisted AI applications are reshaping mobile traffic patterns. Industry forecasts, including those published by the Mobile Optical Pluggables Alliance (MOPA), point to a 3x–5x increase in uplink capacity requirements as devices offload heavy AI inference to the cloud. This shift lands hardest on the fronthaul, where the encoding overhead of uplink traffic leaves less headroom to grow, making 50G optics increasingly critical to fronthaul design.

“The optical layer is the foundation of the AI-era mobile network,” said Stefan Dahlfort, president of the Mobile Optical Pluggables Alliance (MOPA). “With operators and system vendors now committing to 50G fronthaul, the industry needs interoperable, high-volume silicon solutions ready today. Semtech’s portfolio supports MOPA's blueprints and the broader introduction of 5G-Advanced.”

“Bringing 50G optical modules to volume requires close partnership between module makers and silicon suppliers,” said Frank Chang, chief technology officer at Source Photonics. “Semtech's CDR and TIA portfolio gives us the flexibility and performance we need to deliver across the full range of fronthaul architectures our customers are deploying.”

“AI is rewriting the rules of mobile traffic, and the uplink is now one of the critical dimensions,” said Raza Khan, director of wireless marketing with Semtech's signal integrity products group. “With the industry’s latest radios moving to 50G interfaces, customers need a complete, qualified solution they can deploy today, not a roadmap promise. Semtech’s wireless portfolio enables the various architectures that the industry is building.”

Now shipping in volume, Semtech’s portfolio enables system vendors and operators to deploy the fronthaul architecture required by many of today's radio platforms:

• 10 km duplex links: GN2255 Clock and Data Recovery (CDR) paired with the GN1700TI Transimpedance Amplifier (TIA)
• 15 km bidirectional (BiDi) links: GN2255S CDR paired with the GN1700TI TIA
• Wavelength Division Multiplexing (WDM) and longer-reach architectures: GN2256 CDR paired with the GN1700TI TIA

Built on Semtech’s ClearEdge®, Tri-Edge™ and FiberEdge® product families, the portfolio enables 50G fronthaul deployments for 5G-Advanced today and is designed to scale toward 6G through 2030.

Semtech continues to work with module partners and system vendors across the ecosystem to support the transition to 5G-Advanced and, ultimately, 6G.
