Description

Dual-port 100GbE QSFP28 SmartNIC designed for programmable packet acceleration and ultra‑low-latency networking. The KU3P FPGA enables custom data-path offload, filtering, tunneling, and telemetry. Each port supports 100G line rate or 4x25G via breakout for flexible deployment. Compatible with standard QSFP28 SR4/LR4 optics and DAC/AOC cables. Ideal for HFT, storage acceleration, telecom, and cloud edge workloads.

Features

- Dual 100GbE QSFP28 ports for high-throughput connectivity
- Programmable KU3P FPGA data path for advanced offloads
- Flexible 8x25G breakout to align with spine/leaf architectures
- Broad QSFP28 optic and cable interoperability
- Low-latency pipeline suitable for performance-critical workloads
- Scalable from 25G lanes to full 100G per port
