Description

High-performance passive copper breakout DAC that splits one 800G NDR OSFP port into two independent 400G NDR QSFP112 links for ultra‑low‑latency, short‑reach intra‑rack connectivity. Zero‑power, plug‑and‑play operation with precise lane mapping (8‑lane OSFP to 2x 4‑lane QSFP112). Ideal for switch-to-adapter or switch-to-switch breakouts in dense HPC fabrics.

Features

- 800G OSFP to dual 400G QSFP112 NDR breakout
- Passive, zero‑power, ultra‑low latency
- Optimized for short‑reach intra‑rack connectivity
- Accurate 8‑lane to 2x 4‑lane PAM4 lane mapping
- Plug‑and‑play integration with NDR switch and adapter ports

Technical Specifications

FAQs

Q: Does this cable require separate transceivers?
A: No. As a passive DAC, the connectors integrate the electrical interface—no separate optics are required.

Q: Can I use this with Ethernet 800G/400G ports?
A: It is engineered for InfiniBand NDR. Some Ethernet ports may not accept NDR‑coded DACs; check your device’s DAC coding and compatibility.

Q: What is the maximum reach?
A: The reach equals the fixed cable length of 1m. Passive DACs are intended for short‑reach intra‑rack connections.

Q: Does each leg operate as an independent 400G link?
A: Yes. The OSFP 800G port is broken out into two independent 400G QSFP112 links.

Q: Any handling guidelines?
A: Avoid sharp bends or crushing the cable; follow standard DAC handling practices for reliable performance.
