Description

Passive copper splitter cable for breaking out one 800G OSFP port into two independent 400G QSFP112 links. Suited for leaf/spine aggregation and GPU/accelerated computing clusters that need zero‑power, ultra‑low‑latency connectivity over 3 meters across Ethernet or InfiniBand NDR‑class networks.

Features

1×800G OSFP to 2×400G QSFP112 breakout
- Zero‑power, ultra‑low‑latency passive copper construction
- Standards‑compliant CR8 to CR4 lane mapping
- 3 m reach for flexible rack layouts
- Rugged OSFP/QSFP112 connectors with secure latches
- Optimized for high‑performance Ethernet and InfiniBand fabrics

FAQs

Q: Will this work with 800G OSFP switch ports to connect 400G devices?
A: Yes, if the 800G port supports 2x400G breakout and the devices have QSFP112 400G ports.

Q: Do I need firmware or port configuration?
A: Most platforms require enabling 2x400G breakout on the 800G port; consult the device documentation.

Q: Is this an active or passive assembly?
A: Passive—no power draw and the lowest possible latency.

Q: Can it be mixed across Ethernet and InfiniBand?
A: It can be used with either protocol as long as both ends support the electrical signaling and breakout mode.

Q: What distance can I expect?
A: This model is 3 m; passive copper at these speeds is generally limited to short intra‑rack runs.
