High-performance passive copper breakout DAC for splitting one 400G OSFP port (2x200G lanes) into four independent 100G QSFP56 links. Ideal for InfiniBand NDR-to-HDR/HDR100 topologies where ultra-low latency and short-reach rack interconnects are required. The 1 m twinax assembly provides robust signal integrity without active components, simplifying deployment and minimizing power draw.

Low-latency passive twinax for shortest possible link delay
- Simple deployment—no separate optics required
- Breakout flexibility for high-density leaf/spine and adapter fan-out
- Robust shielding for signal integrity at 50G PAM4 lane rates
- Purpose-built for short-reach, in-rack or adjacent-rack connections
