Dell 470-ADFD Compatible 200G QSFP-DD 8 x 25G NRZ Passive Copper Twinax Cable, 2m (7ft)

The 470-ADFD cable offers a direct QSFP-DD to QSFP-DD connection at 200Gbps. Its 2m (7ft) length and DAC construction are intended for Dell equipment, with no separate transceiver-and-patch-cord assembly required.

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: 2m (7ft), 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.

470-ADFD occupies the middle of this family between 470-ADFD at 1.5m (5ft) and 470-ADFD at 2.5m (8ft). 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.

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.

470-ADFD provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

The assembly is configured for equipment that recognizes 470-ADFD. 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.

When ordering, specify 470-ADFD, cable length 2m (7ft) 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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
