Digitus Professional SFP+ 10G DAC Cable — 1 m, MSA universal coded
1 mSFP+ to SFP+10 GbpsMSA coded
The Digitus Professional DN-81221 is a 1 m SFP+-to-SFP+ direct attach copper (DAC) cable that links two 10G ports — switch to switch, switch to server network card or switch to storage — without buying two optical transceivers and a fibre patch cord.
It is coded to the open SFP+ MSA, for ports that accept standard, non-vendor-locked modules. Digitus specifies it for 10 Gigabit Ethernet and Fibre Channel links between switches in backbone areas, with DDM/DOM support so the switch can read module information.
Before you order: Some switches and network cards (certain Cisco, HPE/Aruba, Juniper and Intel models) only accept their own coded modules or need a setting to allow third-party ones. If yours is one of them, send us the model before ordering and we will tell you which coded version works.
What's in the Box
- 1 × Digitus SFP+ DAC cable, 1 m, with fixed SFP+ plugs on both ends
- 1 × quick installation guide
What It Means in Practice
- 1 m is the usual length for links inside one rack — top-of-rack switch to a server or storage unit a few U below.
- No transceivers to buy: each end is a fixed SFP+ plug, so one cable replaces two short-range optics plus a fibre patch cord — less cost and lower latency on short links.
- Plug it into the SFP+ cage at each end; the link comes up at 10G when both ports support that speed.
- Copper twinax is thicker and stiffer than fibre — leave a gentle loop at the port instead of folding it sharply against the cage.
What Will Not Work
- RJ45 / 10GBASE-T copper ports — a DAC needs a SFP+ cage at both ends.
- QSFP+/QSFP28 ports — this cable has SFP+ plugs and does not fit 40/100G ports without an adapter.
- Runs longer than 1 m — the length is fixed; for longer distances use SFP+ optics and fibre.
- 1G-only SFP ports — many of them do not link with a 10G DAC; check with us first.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
A DAC is the most economical way to connect 10G equipment that sits close together. The two decisions are length and coding: measure the real cable path (not the straight-line distance) and match the coding to the switch brand. Browse our switches if you are planning the rest of the link.
✓ Buy it if you are connecting two SFP+ ports up to 1 m apart on equipment that accepts MSA modules.
✕ Skip it if your ports are RJ45, your run is longer than 1 m, or your switch only accepts its own vendor-coded modules.
→ Also consider Other lengths of the same Digitus SFP+ DAC (0.5, 1, 2, 3 and 5 m), or the HPE-coded versions for HPE/Aruba switches.
Not sure which coding or length you need? Send us the switch and network card models and we will check compatibility before you order.
