Dell 470-ACEY Compatible 25G SFP28 Passive Copper Twinax Cable, 4m (13ft)

For short, high-density connections, this DAC cable combines 25G performance with a fixed 4m (13ft) cable run. It corresponds to Dell 470-ACEY and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: 470-ACEYHT Part Number: 470-ACEY

Product Highlights

• Compatible alternative to Dell 470-ACEY
• 25G connectivity at 25Gbps
• Interface configuration: SFP28 to SFP28
• Fixed length and part number: 4m (13ft), 470-ACEY
• Conductor specification: 26AWG
• Minimum bend radius: 28mm

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 28mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The 4m (13ft) length gives 470-ACEY more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

470-ACEY occupies the middle of this family between 470-ACEU at 3m (10ft) and 470-ACEY at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The intended application is 25G Ethernet, Data Center, 5G Wireless. Listed interface and protocol references include IEEE 802.3, SFP28 MSA, SFF-8402, Infiniband, EIA 364-1000. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

The assembly is configured for equipment that recognizes 470-ACEY. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

This product is ordered as 470-ACEY in 4m (13ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
