Semtech Launches 10G PON Chipset for 50G OLT Modules

  • Semtech introduced a 10G PON chipset for 50G OLT modules, supporting GPON, XGS-PON, and 50G PON in a compact SFP-DD form factor.
  • The GN7153C OLT combo IC and GN28L46 burst-mode TIA offer 6.5W system-level power savings across a 16-port OLT.
  • The chipset integrates dual-rate burst-mode limiting amplifier, laser bias driver outputs, and high-sensitivity TIA, reducing component count and BOM cost.
  • Sampling is available now, with volume production scheduled for September 2026.

Semtech's new chipset addresses the growing need for high-density, low-power solutions in the transition to 50G PON networks. As broadband infrastructure evolves, the ability to support multiple generations of PON technology within space-constrained modules becomes critical. This development aligns with the broader trend of optimizing power efficiency and component integration in optical networking equipment.
