Description

Passive twinax copper breakout cable that converts a single 800G OSFP port into four 200G QSFP112 downlinks. Ideal for short‑reach aggregation and spine/leaf breakouts in data centers using Ethernet or InfiniBand NDR‑class systems, delivering zero power draw and minimal latency over 3 meters.

Features

1×800G OSFP to 4×200G QSFP112 breakout
- Zero‑power, ultra‑low‑latency passive copper
- Standards‑aligned CR8 to CR2 lane mapping
- 3 m reach for flexible intra‑rack routing
- Robust latching OSFP/QSFP112 connectors
- Optimized for high‑density Ethernet and InfiniBand NDR fabrics

FAQs

Q: Can this be used between an 800G switch and 200G NICs?
A: Yes, if the 800G OSFP port supports 4x200G breakout and the NIC ports are QSFP112 200G.

Q: Does it support Ethernet and InfiniBand?
A: Yes, provided the devices’ OSFP/QSFP112 ports support the corresponding breakout and signaling.

Q: Is any configuration needed on the switch?
A: Most platforms require enabling 4x200G breakout on the 800G port; consult the switch OS for details.

Q: Is it active or passive?
A: Passive DAC—no power, lowest latency.

Q: What is the maximum supported length for passive DAC at these speeds?
A: Typically up to 2–3 meters depending on platform and signal integrity; this assembly is 3 m.
