Dell 470-ACEY Compatible 25G SFP28 Passive Copper Twinax Cable, 2.5m (8ft)

This HT cable matches the 470-ACEY requirement for Dell equipment. The 2.5m (8ft) assembly supports 25G operation and provides a factory-terminated passive copper link without separate optical modules or patch cords; its complete electrical and mechanical details are listed below.

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: 2.5m (8ft), 470-ACEY
• Conductor specification: 30AWG
• Minimum bend radius: 21.25mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21.25mm. 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.

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 2.5m (8ft) version is useful when a two-metre run would leave insufficient working slack. Before installation, check the complete horizontal and vertical path so that 470-ACEY reaches both ports without tension at either connector.

470-ACEY occupies the middle of this family between 470-ACFB at 2m (7ft) and 470-ACEU at 3m (10ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. 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.

Each 470-ACEY compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Dell platform should be included with the order.

When ordering, specify 470-ACEY, cable length 2.5m (8ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, 470-ACEY and the 2.5m (8ft) length for easier inventory control.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
