Description

High-performance 100G direct-attach copper cable for short-reach, low-latency interconnects between QSFP28 100G ports. The passive twinax design minimizes power draw and simplifies deployment for top-of-rack and spine/leaf links where a compact 0.5 m run is ideal.

Features

Zero additional power consumption and minimal latency
- Tool‑less, plug‑and‑play connectivity between adjacent racks
- Robust twinax construction for reliable signal integrity
- Cost‑effective alternative to optics for short distances

FAQs

Q: Is this cable active or passive?
A: It is a passive direct-attach copper (DAC) cable.

Q: Which ports does it work with?
A: Any device with QSFP28 100G-capable ports that support passive DACs. Check your switch/NIC documentation for DAC compatibility.

Q: Can it be used for lengths longer than 0.5 m?
A: This specific assembly is 0.5 m. For longer runs, select an appropriately rated DAC length or use optical transceivers with fiber.

Q: Does it support breakout to 4×25G?
A: This is a straight (non‑breakout) QSFP28‑to‑QSFP28 cable. Breakout support depends on a different cable type and device capabilities.
