About the Panduit 25Gb SFP28 Direct Attach Copper Twinax Cable 3M
The Panduit 25Gb SFP28 Direct Attach Copper (DAC) Twinax Cable delivers native 25 gigabit per second connectivity with passive copper construction, eliminating the power consumption and heat generation associated with active optical transceivers. Purpose-built for server-to-leaf switch architectures in modern AI training clusters and ultra-low-latency trading infrastructure, this 3-meter cable provides sub-microsecond latency propagation ideal for time-sensitive workloads. The twinax design offers superior EMI shielding in dense rack environments while maintaining backward compatibility with standard SFP28 ports across Broadcom, Mellanox, and Cisco switching platforms.
Launched in Q3 2023, this cable addresses the accelerating enterprise migration from 10GbE to 25GbE server-to-leaf switching topologies, driven by the computational demands of distributed AI model training and high-frequency algorithmic trading systems. Panduit's implementation meets IEEE 802.3by specifications with tested performance across extended temperature ranges and high-vibration datacenter environments. The 3-meter length bridges top-of-rack to mid-row leaf switches while maintaining deterministic signal integrity without regeneration or electronic intervention.
Ideal for
- AI training cluster fabric interconnects connecting compute nodes to 25GbE leaf switches with sub-10µs latency SLA requirements
- High-frequency trading infrastructure requiring microsecond-precision packet delivery between market data feeds and execution engines
- Server-to-storage array connections supporting NVMe-over-Fabrics (NVMeoF) at 25Gb/s with predictable latency
- Hyper-scale datacenter rack aggregation for machine learning workloads leveraging distributed GPU clusters
- Fintech risk management and analytics platforms demanding deterministic network performance under burst traffic
- Dense 25GbE spine-leaf fabric deployments in colocation facilities where power efficiency and heat reduction are critical
