Description

High‑performance active copper cable for InfiniBand NDR twin‑port OSFP links delivering up to 800 Gb/s aggregate bandwidth with ultra‑low latency and power versus optics. 3m reach is ideal for in‑rack switch‑to‑GPU or switch‑to‑switch connections. Flat‑Top heatsinks on both ends suit platforms requiring low‑profile thermal clearance. Plug‑and‑play—no separate transceivers required.

Features

- Up to 800G aggregate bandwidth with ultra‑low latency
- Twin‑port OSFP connectors on both ends for NDR platforms
