D-Link DEM-CB100Q28 — Passive 100G QSFP28 DAC

100GQSFP281 m30 AWG

DEM-CB100Q28 is a 1 m passive DAC with QSFP28 at both ends for nearby 100 Gbps links. D-Link specifies it for physical stacking of DXS-3610 Series switches. Measure the route between ports together with the 34.5 mm minimum bend radius so the length permits suitable cable routing.

Compatibility — check before buying:
Confirm 100G QSFP28 ports, equipment models and stacking configuration at both ends. DEM-CB100Q28 has one QSFP28 plug per end; DEM-CB100Q28-4S28 is a separate breakout cable.

Key Features

 
Two-port 100G link
The single QSFP28 assembly connects two compatible ports without a four-way breakout.
 
DXS-3610 stacking reference
The official page identifies it as a physical stacking cable for DXS-3610 Series.
 
Defined bend limit
A 34.5 mm minimum bend radius helps plan routing around rack guides and ports.

What's in the Box

1 D-Link DEM-CB100Q28 cable, 1 m, with two integrated QSFP28 plugs

What Will Not Work

Not a QSFP28-to-four-SFP28 25G breakout cable.
Does not connect directly to RJ45 or SFP+ and does not establish compatibility with every 40G QSFP+ port.
Not suitable for a route exceeding 1 m or requiring bends tighter than 34.5 mm radius.

Frequently Asked Questions

Does it connect four 25G devices?
No. This SKU has one QSFP28 plug at each end. Breakout use requires a different cable and a supported switch configuration.
Will it work in every 40G QSFP+ port?
The specification is for 100G QSFP28. Similar size is insufficient; check the exact switch and its port/cable support.
Is 1 m enough if the ports are exactly 1 m apart?
Measure the actual route, including guides and bends. Allow routing space to respect the 34.5 mm minimum bend radius.
Singular Expert Insight
Check the stacking or link configuration first, then measure the route. For a different distance or port type, select a suitable DAC with verified support rather than forcing a tighter bend in this cable. Compare DAC cables by length and connection type

Buyer’s Guide

Buy it if

You need a supported 1 m 100G QSFP28 link or DXS-3610 stacking connection.

Skip it if

You need a 4 × 25G breakout, a different port or a longer route.

Also consider

The correct DAC length and plugs for the exact hosts and cable route.
