At the Optical Fiber Communication (OFC) 2024 exhibition in San Diego, California, from Mar. 26 to 28, Semtech’s live demonstration in Semtech’s booth #5301 will include:

  • 400Gbps SR4 LPO modules and 800G SR8 LPO modules, featuring Semtech’s DirectEdge GN1858 quad VCSEL driver and GN1856 quad TIA, interoperating in isolation with latest switch ASIC technology as well as with the latest Network Interface Card (NIC) technology, emulating a Top of Rack to NIC arrangement
  • 400Gbps DR4 LPO module featuring Semtech’s FiberEdge MZM driver and GN1814 quad TIA, interoperating with latest switch ASIC technology
  • 400Gbps FR4 LPO module featuring Semtech’s FiberEdge EML driver and GN1817 quad TIA, interoperating with latest switch ASIC technology
  • 800Gbps DR8 LPO module featuring Semtech’s FiberEdge EML driver, GN1825 octal TIA and GN8089 Semtech’s own PIC (Photonic Integrated Circuit), interoperating with latest switch ASIC technology

In addition, 400Gbps SR4 and DR4 LPO modules with Semtech’s PMDs will be interoperating with latest switch ASIC technology and other LPO modules from multi-vendor ecosystem in OIF’s booth #1323.

“The demonstration of a vast number of ready-to-adopt multi-mode and single-mode LPO modules in Semtech’s booth at OFC this year to the extensive PMDs already present in the FiberEdge product line, reflects Semtech’s commitment to support LPO and take it to the next adoption level,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “Reliable signal integrity, equalization and flexibility are key to make LPO successful, and Semtech’s DirectEdge and FiberEdge PMDs are the perfect candidates for this to match the needs of AI and ML high speed interconnects while reducing optical module power consumption by up to 50% versus DSP based solutions. Data centers are expected to utilize this power savings to deploy increased compute capability. LPO solutions also offer reduced latency and lower costs than DSP based solutions delivering additional value propositions for data centers.”
