Zyxel DAC25G-3M 25 Gbps SFP28 Copper DAC Cable
3 m / 9.84 ftSFP28 to SFP2825 GbpsDirect Attach Copper (DAC)
The Zyxel DAC25G-3M is a complete 3 m Direct Attach Copper cable with integrated SFP28 ends for a direct link between compatible host ports. It is a copper DAC, not a fibre cable or standalone transceiver; both host ports and their firmware must qualify the cable.
Best For: For network installations needing a 3 m direct copper link between compatible 25G SFP28 host ports. Confirm that the exact hardware and firmware at both ends qualify this cable before purchase.
Before you order: This is not RJ45, SFP+ 10G, QSFP28 100G, LC or MPO, and no automatic 10G fallback or universal third-party compatibility is established. Hosts are separate. Check routing and connector clearance within the 3 m length, and follow the supported insertion/removal procedure; disconnecting the cable interrupts the physical link.
What's in the Box
- One complete Zyxel DAC25G-3M cable assembly with two integrated SFP28 ends
What It Means in Practice
- Plan the device separation and cable route within the complete 3 m length; allow for connector clearance without assuming a particular bend radius.
- Check the exact host model, supported 25G SFP28 port and firmware/cable qualification at both ends; physical connector fit alone is not sufficient.
- The cable is powered through supported host connections; no separate external adapter or PoE injector is listed.
- Removing the cable interrupts the physical link, so do not assume a zero-downtime disconnection.
What Will Not Work
- Requires compatible 25G SFP28 host ports and firmware/cable acceptance at both ends; universal third-party compatibility is not established.
- Not an RJ45 cable, SFP+ 10G, QSFP28 100G, LC or MPO connection; no automatic 10G fallback is established.
- A 25 Gbps link class does not guarantee 25 Gbps application payload throughput; actual throughput depends on hosts, configuration and traffic.
- Host switches/NICs, adapters and other cables are not included.
- No standalone switching, routing or Internet function.
Key Features
3 m SFP28-to-SFP28 assembly
Two integrated ends provide a direct copper connection between qualified host ports without separate optical modules or a fibre cable.
25 Gbps link class
Designed for a 25G link; actual application throughput depends on the connected hosts, configuration and traffic.
Host-qualified use
The manufacturer matrix lists CX4800-56F and CX3800 Series; verify the exact host and firmware before ordering.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The 3 m assembly has two integrated SFP28 ends, so this direct link does not require two additional optical modules or a separate fibre cable. Its 25 Gbps link class does not guarantee 25 Gbps payload throughput.
Buyer’s Guide
✓ Buy it if For network installations needing a 3 m direct copper link between compatible 25G SFP28 host ports. Confirm that the exact hardware and firmware at both ends qualify this cable before purchase.
✕ Skip it if This is not RJ45, SFP+ 10G, QSFP28 100G, LC or MPO, and no automatic 10G fallback or universal third-party compatibility is established. Hosts are separate.
