Dell AEC-Q56DD-400G-5M Compatible 400G QSFP-DD 8 x 50G PAM4 Active Electrical Cable, 5m (16ft)

Use the AEC-Q56DD-400G-5M compatible assembly where a 400G connection is required between compatible ports. This page covers the 5m (16ft) version only, with its own HT part number, specifications and compatibility verification.

OEM Part Number: AEC-Q56DD-400G-5MHT Part Number: AEC-Q56DD-400G-5M

Product Highlights

• Compatible alternative to Dell AEC-Q56DD-400G-5M
• 400G connectivity at 400Gbps
• Interface configuration: QSFP-DD to QSFP-DD
• Fixed length and part number: 5m (16ft), AEC-Q56DD-400G-5M
• Cable construction: Active DAC (AEC)
• Conductor specification: 28AWG
• Maximum power consumption: 10W Per End
• Minimum bend radius: 53mm

The listed modulation format is 8x 50G-PAM4. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

The rated power consumption is 10W 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.

This assembly uses 28AWG conductors, PET jacket, minimum bend radius 53mm. 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 QSFP-DD MSA, IEEE 802.3cd, CMIS 5.0. Confirm that the host firmware and port configuration support the same operating mode.

The 5m (16ft) length gives AEC-Q56DD-400G-5M more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the AEC specification and host support must still match the intended link.

AEC-Q56DD-400G-5M is the longest of 4 verified length options in this family. Compared with AEC-Q56DD-400G-3M at 3m (10ft), it provides 2m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

Our compatibility setup for Dell AEC-Q56DD-400G-5M is checked together with the physical 5m (16ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

Quote HT part number AEC-Q56DD-400G-5M with the required quantity. The 5m (16ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Every AEC-Q56DD-400G-5M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 5m (16ft) 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.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
