Four 10G connections from a compatible 40G port

3 m assemblyFour SFP+ branchesNo DDM

The DN-81323 connects one QSFP+ port to four SFP+ ports over a fixed 3 m direct attach assembly. It suits nearby switch or server connections where the QSFP+ interface supports 4×10G breakout. Check port mode and DAC acceptance before choosing it.

Compatibility — check before buying:
Requires compatible QSFP+ breakout and SFP+ ports; verify vendor coding and device support.

Key Features

 
One-to-four connection
The QSFP+ end feeds four separate SFP+ branches for 40G-to-4×10G interoperability on supported equipment.
 
Fixed 3 m reach
An integrated cable and connector assembly avoids separate transceivers for this short connection. Allow enough routing space for all four branches.
 
Specified electrical interface
The manufacturer specifies 10.3125 Gbps per channel, nominal 3.3 V supply and serial I2C management. DDM is not supported.

Frequently Asked Questions

Will it work in any QSFP+ port?
No. The host must support 4×10G breakout and accept the cable. DIGITUS lists multiple equipment vendors, but support depends on the exact device and firmware.
Is each SFP+ branch a 40G link?
No. The assembly maps the 40G QSFP+ connection to four 10G channels; 10.3125 Gbps is the specified channel data rate.
Does it provide digital diagnostic monitoring?
No. The datasheet explicitly lists no DDM support.
Singular Expert Insight
A QSFP+ socket alone does not guarantee breakout operation. Confirm that the specific device can divide its 40G port into four 10G channels and accepts this DAC coding. Confirm your switch or server connection with Singular

Buyer’s Guide

Buy it if

Your supported 40G QSFP+ port needs four nearby 10G SFP+ connections within 3 m.

Skip it if

You need a single 40G-to-40G link, a longer run or a port without breakout support.

Also consider

For uncertain device support, share the exact switch or server model with Singular before selecting the DAC.
