Semtech Breakthrough Unlocks Mass Deployment of 50G Fiber Networks

The global fiber broadband market faces a critical challenge: surging bandwidth demands from Artificial Intelligence (AI) applications, cloud gaming and remote work are pushing current networks to their limits. While 50G PON technology helps solve bandwidth and infrastructure challenges, early 50G triple-gen OLT prototypes have been power-hungry and non-compliant with standards.

Semtech’s new chipset uses advanced mixed signal equalization and high levels of integration to solve these challenges. Reduced power consumption and chip scale packaging enables a compact SFP-DD module form factor and helps the OLT system meet critical size, heat dissipation and port density requirements for scalable deployment. Full ITU compliance ensures seamless integration into carrier networks supporting GPON, XGSPON and HS-PON standards.

“As carriers prepare for the first large-scale deployments of asymmetric 50G PON in the U.S. and Asia, our new chipset is a game-changer,” said Jacqui Adams, senior product line manager at Semtech. “Carriers can now plan their network upgrades with confidence, offer their clients a range of new services and know they have a solution that meets strict network standards.”
