Dell 470-ADFD Compatible 200G QSFP-DD 8 x 25G NRZ Passive Copper Twinax Cable, 2.5m (8ft)

With a fixed 2.5m (8ft) cable and QSFP-DD to QSFP-DD, the 470-ADFD compatible assembly simplifies 200G deployment. It is manufactured and tested by HT for Dell equipment.

OEM Part Number: 470-ADFDHT Part Number: 470-ADFD

Product Highlights

• Compatible alternative to Dell 470-ADFD
• 200G connectivity at 200Gbps
• Interface configuration: QSFP-DD to QSFP-DD
• Fixed length and part number: 2.5m (8ft), 470-ADFD
• Cable construction: Passive Twinax
• Conductor specification: 28AWG
• Maximum power consumption: 0.1W Per End
• Minimum bend radius: 40.5mm

The rated power consumption is 0.1W Per End. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3bj, QSFP-DD MSA, CMIS, SFF-8417. 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 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-ADFD reaches both ports without tension at either connector.

470-ADFD occupies the middle of this family between 470-ADFD at 2m (7ft) and 470-ADFD 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.

This assembly uses 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. 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.

Each 470-ADFD 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.

Use part number 470-ADFD for the 2.5m (8ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Every 470-ADFD compatible assembly undergoes link testing, compatibility verification and visual inspection. The 2.5m (8ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
