Samtec showcases 200+ Gbps active channels at OFC 2025

Samtec will showcase active demonstrations of cables and connectors supporting data rates up to 224Gbps PAM4 and signals up to 110GHz.

Introducing co-packaged connectivity for 200+G

In Booth #5863, Samtec will unveil an active channel demonstration with its technical partner Broadcom, introducing the capabilities of the new Si-Fly HD co-packaged cable assemblies to Samtec Flyover OSFP over the new Samtec Eye Speed Hyper Low Skew twinax cable. This evaluation platform incorporates Broadcom’s 200G SerDes technology and Samtec’s co-packaged Flyover technology. Si-Fly HD CPC offers the industry’s highest footprint density and robust interconnect which enables 102.4T (512 lanes at 200G) in a 95 x 95mm chip substrate.

Co-packaged copper connectivity eliminates insertion losses in the BGA breakout and the PCB. This technology makes a complete 224G passive DAC channel possible, enabling a low-power, cost-effective linear pluggable optics front panel solution with immense potential for connectivity in emerging AI architectures.

Interconnect demonstrations

Samtec will also be showing Si-Fly HD near-chip configurations operating at 224Gbps; Samtec's Bulls Eye 90GHz ISI Evaluation Board; Samtec’s OCP OAI EXP Module equipped with sixteen 25Gx4 FireFlyTM optical transceivers; and a 112 Gbps PAM4 demonstration incorporating Samtec's new HaloTM optical and copper systems.

OIF interoperability demo

Samtec will be participating in the OIF Interoperability demo at OFC 2025 in booth #5745. This demonstration will highlight advancements in interoperability tailored to address the growing demands of future-oriented data centres, AI/ML technologies, and disaggregated systems.

Samtec’s products will be included in CEI interoperability demonstrations, specifically the 224G long-range demo, 224G very-short-range demo, and 112G linear demo.

• Samtec’s Bulls Eye ISI Evaluation Board offers numerous variable length signal paths with known loss profiles beyond 90 GHz. When combined with Samtec’s Bulls Eye High-Performance Test Systems, the combined solution offers an easy-to-use test platform for evaluating and demonstrating 224Gbps PAM4/448 Gbps PAMx signal performance
• Samtec’s Bulls Eye High-Performance Test System features a high-density space saving design that enables smaller evaluation boards and shorter trace lengths in test and measurement applications. The Bulls Eye block compression mounts adjacent to the SerDes being characterised. End 2 of the cable assembly connects to instrumentation using precision RF connectors as small as 1.00mm
