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 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.

QSFP-DD to QSFP-DD-400G-AEC-2M7FT 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.

QSFP-DD to QSFP-DD-400G-AEC-2M7FT occupies the middle of this family between QSFP-DD to QSFP-DD-400G-AEC-1M3FT at 1m (3ft) and QSFP-DD to QSFP-DD-400G-AEC-3M10FT at 3m (10ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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.

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-2M7FT 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.

Use part number QSFP-DD to QSFP-DD-400G-AEC-2M7FT for the 2m (7ft) 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.

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.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
