J9281D - Aruba X242 10G SFP+ to SFP+ 1m Direct Attach Copper Cable

HPE Aruba J9281D — X242 10G SFP+ to SFP+ 1 m Direct Attach Copper (DAC) Cable

What it is

J9281D is an HPE Aruba 10 GbE Direct Attach Copper (DAC) cable with SFP+ to SFP+ connectors and a 1 meter length.
It provides a plug-and-play copper link between two SFP+ ports — typically used to connect switches, servers, or storage at short distances inside racks or between adjacent racks without needing separate transceivers.

Why buyers pick J9281D (plain English)

Simple and affordable connectivity
Pre-terminated SFP+ plugs mean no optics are required — just plug the cable into both SFP+ slots and you’re linked at 10 GbE.

Very low latency and power usage
Copper DAC cables have extremely low latency and consume no extra power beyond the connected interfaces, making them efficient for short links.

Perfect for short reach
At 1 m, it’s ideal for top-of-rack switch-to-server or switch-to-switch connections in the same rack or neighboring cabinets.

Reliable, predictable performance
Designed for enterprise environments where 10 GbE performance and predictable latency really matter.

Aruba validated
Engineered and tested for Aruba SFP+ ports while also being interoperable with many other SFP+-capable gear.

Use case
Short-distance 10 GbE links between switches, servers, or storage.

Where it fits (and when to choose something else)

Perfect for:

• Top-of-rack switch to server connections

• Adjacent rack or same-rack switch interconnects

• Cost-sensitive 10 GbE connections

• Low-latency, short-reach Ethernet fabrics

Choose something else if:

• You need longer reach → fiber optics (SR/LR) with SFP+ transceivers

• You want multimode flexibility → SR optics + fiber

• You need higher speeds (25/40/100 GbE) → appropriate optics/cables

TL;DR

J9281D is Aruba’s 1 m 10 GbE SFP+ to SFP+ DAC cable:
a straightforward, low-latency copper link for connecting SFP+ 10 GbE ports over short distances in racks and data center environments.
