Dell AEC-Q56DD-400G-1M Compatible 400G QSFP-DD 8 x 50G PAM4 Active Electrical Cable, 1m (3ft)

This HT cable matches the AEC-Q56DD-400G-1M requirement for Dell equipment. The 1m (3ft) assembly supports 400G operation and provides an active electrical link with signal recovery designed for the stated data rate; its complete electrical and mechanical details are listed below.

Product Highlights

• Compatible alternative to Dell AEC-Q56DD-400G-1M
• 400G connectivity at 400Gbps
• Interface configuration: QSFP-DD to QSFP-DD
• Fixed length and part number: 1m (3ft), AEC-Q56DD-400G-1M
• Cable construction: Active DAC (AEC)
• Conductor specification: 32AWG
• Maximum power consumption: 10W Per End
• Minimum bend radius: 26.5mm

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 32AWG conductors, PET jacket, minimum bend radius 26.5mm. 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 QSFP-DD MSA, IEEE 802.3cd, CMIS 5.0. Confirm that the host firmware and port configuration support the same operating mode.

At 1m (3ft), AEC-Q56DD-400G-1M is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

AEC-Q56DD-400G-1M is the shortest of 4 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is AEC-Q56DD-400G-2M at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The HT cable carries the compatibility configuration associated with AEC-Q56DD-400G-1M, while its mechanical assembly remains the fixed 1m (3ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Dell software can request a pre-order check.

Quote HT part number AEC-Q56DD-400G-1M with the required quantity. The 1m (3ft) 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.

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.

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.
