Dell Networking Cable, SFP28 to SFP28, 25GbE, Passive Copper Twinax Direct Attach Cable, 2 Meter

The Dell 470-ACFB is an SFP28 to SFP28 cable that uses copper Twinax conductors in a passive design to push 25GbE traffic across a 2 meter run. It slides straight into compatible Dell switches, servers, and storage units, creating a fast lane for data without the need for additional power or active circuitry.

Because the cable is passive, it introduces almost no added latency and pulls no extra wattage from your rack. Network engineers who need to link a top-of-rack switch to nearby servers, or administrators building short interconnects between adjacent appliances, can deploy it in minutes and keep airflow clear of bulky optics.

Dell certifies the 470-ACFB for its enterprise platforms, so firmware handshakes, diagnostic reporting, and management tools all recognize the link as if it were factory installed. That certification also preserves Dell warranty coverage and technical-support agreements, giving operators peace of mind when every minute of uptime counts.

For data centers aiming to maximize port density and throughput without driving up power or cooling costs, this cable offers a simple, cost-effective step toward a 25 gigabit backbone.
