Semtech to showcase new linear pluggable optical links for AI and ML

Semtech announced the demonstration of 100Gbps/lane linear pluggable optical links featuring Semtech''s PAM4 PMDs from its FiberEdge product line and from its new DirectEdge brand,

Agilex™ 7 SoC FPGAs Enable 400G-DR4-LPO Optical Modules

The highest data rate is 116 Gbps PAM4 / 58 Gbps NRZ (labeled as ''FHT'' transceivers) alongside the general-purpose 1- 58 Gbps (labeled as ''FGT'' transceivers) I/Os.

LPO MSA Specification

It builds on IEEE 802.3 and OIF CEI-112G-LINEAR-PAM4 specifications. It enables Ethernet-like links with 1, 2, 4, or 8 lanes for data centers, using low power, high port density, low cost, and low latency

Presentation

This demonstration uses a Time Domain Network Analyzer to show channel characteristics of a cabled near chip and cabled host connectivity (XXmm) plus OSFP break-out test fixturing, totaling over 20

Update on component and channel characterization for optical

High bandwidth EML & PD+TIA performance was updated. An EOL sensitivity of -5dBm per lane at the (stressed) receiver interface is feasible for 4x200G based IM-DD solutions. The CD penalties are
