QSFP-DD to QSFP-DD-400G-AEC-5M16FT 400G QSFP-DD 8 x 50G PAM4 Active Electrical Cable, 5m (16ft)

For short, high-density connections, this AEC cable combines 400G performance with a fixed 5m (16ft) cable run. It corresponds to Generic QSFP-DD to QSFP-DD-400G-AEC-5M16FT and uses an active electrical link with signal recovery designed for the stated data rate.

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.

The 5m (16ft) length gives QSFP-DD to QSFP-DD-400G-AEC-5M16FT 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.

QSFP-DD to QSFP-DD-400G-AEC-5M16FT is the longest of 4 verified length options in this family. Compared with QSFP-DD to QSFP-DD-400G-AEC-3M10FT 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.

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.

Each QSFP-DD to QSFP-DD-400G-AEC-5M16FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

When ordering, specify QSFP-DD to QSFP-DD-400G-AEC-5M16FT, cable length 5m (16ft) 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.

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-5M16FT and the 5m (16ft) length for easier inventory control.

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.
