HPE 537963-B21 SFP+ Direct Attach Copper Cable

HPE 537963‑B21 – 5 m 10 Gb/s SFP+ to SFP+ Direct Attach Copper Cable

Overview

The HPE 537963‑B21 is a 5‑metre passive twinax direct‑attach copper (DAC) cable featuring SFP+ plug‑in modules at each end, specifically rated for 10 Gb/s Ethernet links between SFP+ ports. It’s designed for short‑reach, high‑speed links such as server‑to‑top‑of‑rack switch or blade chassis interconnects where fibre or active optics are not required. Because it uses a copper twinax construction with SFP+ form factor, it fits standard server optics cages but stays cost‑effective and efficient for distances up to 5 m. Ideal use‑cases include blade server chassis or high‑density rack server environments where latency, power and cost matter.

Key Features

• Passive twinax copper cable assembly, SFP+ at both ends, for 10 Gb/s data‑rates over 5 metres — cost‑effective for short‑distance links.

• SFP+ to SFP+ form‑factor supports insertion into standard server or switch SFP+ cages — no separate breakout modules required.

• Compatible with the HPE BladeSystem c‑Class and other supported HPE platforms — simplifies deployment and maintains vendor support.

• RoHS compliant and industry SFP+ MSA compliant, helping ensure signal integrity and compatibility with multi‑vendor setups.
