Keysight to Demonstrate AI Innovations at OFC 2025  

Join Keysight experts for the following demonstrations featuring the latest innovations in optical transmission and data center interconnect — powering next-gen AI experiences: 

Research and Design Simulation 

• 448 Gbps Optical Research: Keysight will demonstrate its first 448 Gbps transmission using Keysight’s AWGs to drive an optical 448 Gbps PAM-4 modulator. 448G is the key enabler of 3.2Tb networks needed primarily for next-gen AI data center networks.
• Photonics IC Testing: Keysight will illustrate how to verify photonics integrated circuits (PIC) at the wafer / die levels using a probing technology platform. PICs are instrumental in innovating data center interconnects for speed and power performance.
• Keysight Photonic Designer: This demo will illustrate how to verify photonic integrated circuits (PIC) at the wafer/die levels. 

Transceiver Solutions

• 1.6 T Optical Tx Validation: This demo will showcase the new Keysight N1093B DCA-M to measure a TeraHop 1.6 T optical transceiver module, displaying an eye diagram and key measurements including TDECQ, OMA and RLM. 
• 224 G Interconnect Validation: This demo will showcase Keysight’s solution for validating the optical receiver interface of two energy-efficient 224G interconnect candidates: linear pluggable optics and retimed transmitter, and linear receiver optical modules. 
• 1.6 Interconnect Testing: Keysight will demonstrate its benchtop test system and the new interconnect test software with level-one stats validating BER/FEC and qualifying interconnects. This solution provides complete, high-quality interconnect testing, saving time, and ensuring accurate data transmission.

These three solutions are essential to enabling 1.6T transceiver development and compliance, scaling manufacturing and production, and ensuring reliability in AI data center networks with comprehensive Layer 1 – 3 testing.
