“With the production of our FiberEdge GN1700 and Tri-Edge 5G portfolio including GN2255 and GN2256, our customers can now enable successful pilot qualifications for 50Gbps PAM4 systems,” said Raza Khan, senior market manager for Semtech’s Signal Integrity Products Group. “This is a great milestone and a testament to Semtech’s on-time execution on our innovative product offerings.”

50Gbps PAM4 architectures will be used to enable 5G deployments such as 64T64R Massive MIMO-based macro base stations and mmWave small base stations. IC technology that enables optical fiber communication in these deployments is a critical part of the network enabling the wired backbone of this architecture. Semtech is continuing to execute ahead for its customer’s and their customer’s needs. Semtech’s FiberEdge GN1700 production paired with Semtech’s Tri-Edge 5G ICs (GN2255 and GN2256) now enables our customers to achieve volume deployments for advanced 50G PAM4 5G front haul architectures.
