Zyxel DAC25G-1M 25 Gbps SFP28 DAC Cable
25 GbpsSFP28 to SFP281 mDirect Attach Copper
The Zyxel DAC25G-1M is a complete 1 m direct-attach copper cable with an integrated SFP28 end at each side. It provides a short 25 Gbps-class link between compatible host ports, subject to support by the exact host hardware and firmware. Hosts are separate.
Best For: For connecting two compatible 25G SFP28 host ports over a short 1 m copper link. Confirm that the exact devices, ports and firmware qualify this cable before purchase.
Before you order: This is not a universal SFP28 cable: physical fit alone does not establish host or firmware acceptance. Both host devices are separate. The 25 Gbps figure is the link class, not guaranteed application payload throughput. No automatic 10G fallback or third-party compatibility is established.
What's in the Box
- One complete Zyxel DAC25G-1M cable assembly with two integrated SFP28 ends
What It Means in Practice
- The 1 m length is the complete cable length, not an optical transmission reach; plan the device separation and routing within that length.
- Check the exact host model, supported 25G SFP28 port and firmware/cable qualification at both ends before installation.
- Insert and remove the cable using the supported host-port procedure, avoid strain and allow connector clearance; disconnecting it interrupts the physical link.
What Will Not Work
- Requires compatible 25G SFP28 host ports and firmware/cable acceptance at both ends; connector fit alone is insufficient.
- Not RJ45, SFP+ 10G, QSFP28 100G, LC or MPO. No automatic 10G fallback, stacking, LAG, fan-out or universal third-party compatibility is established.
- Hosts are not included. No separate optical modules or fibre cable are needed for this direct link; the assembly is not two separately usable optical modules.
- No standalone switching, routing or Internet function. Application throughput depends on the hosts, configuration and traffic; 25 Gbps payload is not guaranteed.
Key Features
Integrated SFP28 ends
Both ends are part of the cable assembly for a direct SFP28-to-SFP28 connection.
1 m copper DAC
A short direct-attach copper link for supported host ports; the stated length is not optical reach.
25 Gbps link class
Identifies the link class, while actual application throughput depends on host and traffic conditions.

Frequently Asked Questions
Singular Expert Insight
It is a complete 1 m copper DAC assembly with both SFP28 ends integrated, so this direct link does not require two additional optical modules or a separate fibre cable.
Buyer’s Guide
✓ Buy it if For connecting two compatible 25G SFP28 host ports over a short 1 m copper link. Confirm that the exact devices, ports and firmware qualify this cable before purchase.
✕ Skip it if This is not a universal SFP28 cable: physical fit alone does not establish host or firmware acceptance. Both host devices are separate. The 25 Gbps figure is the link class, not guaranteed application payload throughput. No automatic 10G fallback or third-party compatibility is established.
→ Also consider If your devices do not have qualified 25G SFP28 ports, choose a connection type specifically supported by both hosts instead; this cable is not RJ45 or an optical link.
