A short passive copper link between two 25G ports

Passive twinax2 m25G SFP28

The DN-81242 is a fixed 2 m passive direct attach cable with an SFP28 connector at each end. Its shielded copper twinax construction suits short connections between compatible 25G switch, server or storage ports. Confirm that both devices accept the DAC and its vendor coding before ordering.

Compatibility — check before buying:
Exact device and vendor coding support must be confirmed; general manufacturer compatibility is not universal port support.

Key Features

 
Integrated short link
The cable and two SFP28 ends form one assembly, avoiding separate optical modules for this compatible 2 m copper connection.
 
Shielded 30AWG twinax
Shielded copper twinax provides the specified cable construction. Leave sufficient routing room and handle the connectors rather than pulling the cable.
 
Documented electrical limits
DIGITUS specifies a 25.88243 Gbps channel data rate, nominal 3.3 V supply and power consumption below 0.5 W. DDM is not supported.

Frequently Asked Questions

Can I assume it works in any SFP+ port?
No. This is specified as an SFP28 25G DAC. Check the supported port speed, DAC type and coding on both devices.
Is it an optical cable?
No. It is a passive shielded copper twinax direct attach cable.
Does it include DDM monitoring?
No. The manufacturer explicitly states that DDM is not supported.
Singular Expert Insight
Match the cable to two compatible SFP28 25G ports. A physically similar SFP+ socket or a vendor name on a general compatibility list does not establish that the exact device supports this 25G DAC. Confirm both 25G device ports with Singular

Buyer’s Guide

Buy it if

You need a 2 m connection between two compatible 25G SFP28 ports.

Skip it if

You need optical reach, a breakout cable or ports that do not accept this DAC.

Also consider

Verify both device models and available cable routing space before choosing the fixed 2 m length.
