QSFP-DD to QSFP-DD-400G-AEC-1M3FT 400G QSFP-DD 8 x 50G PAM4 Active Electrical Cable, 1m (3ft)

For short, high-density connections, this AEC cable combines 400G performance with a fixed 1m (3ft) cable run. It corresponds to Generic QSFP-DD to QSFP-DD-400G-AEC-1M3FT and uses an active electrical link with signal recovery designed for the stated data rate.

OEM Part Number: QSFP-DD to QSFP-DD-400G-AEC-1M3FTHT Part Number: QSFP-DD to QSFP-DD-400G-AEC-1M3FT

Product Highlights

• HT-manufactured AEC assembly in 1m (3ft)
• 400G connectivity at 400Gbps
• Interface configuration: QSFP-DD to QSFP-DD
• Fixed length and part number: 1m (3ft), QSFP-DD to QSFP-DD-400G-AEC-1M3FT
• 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), QSFP-DD to QSFP-DD-400G-AEC-1M3FT 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.

QSFP-DD to QSFP-DD-400G-AEC-1M3FT 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 QSFP-DD to QSFP-DD-400G-AEC-2M7FT at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Compatibility is more than matching the QSFP-DD to QSFP-DD shape. This assembly is prepared for hosts expecting QSFP-DD to QSFP-DD-400G-AEC-1M3FT and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as QSFP-DD to QSFP-DD-400G-AEC-1M3FT in 1m (3ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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, QSFP-DD to QSFP-DD-400G-AEC-1M3FT and the 1m (3ft) length for easier inventory control.

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.
