QSFP-DD-400G-ACC-5M16FT 400G QSFP-DD 8 x 50G PAM4 Active Copper Twinax Cable, 5m (16ft)

This 5m (16ft) ACC cable is built for multi-vendor equipment requiring the QSFP-DD-400G-ACC-5M16FT interface. The 425Gbps link uses QSFP-DD and is supplied as one complete tested assembly.

OEM Part Number: QSFP-DD-400G-ACC-5M16FTHT Part Number: QSFP-DD-400G-ACC-5M16FT

Product Highlights

• HT-manufactured ACC assembly in 5m (16ft)
• 400G connectivity at 425Gbps
• Interface configuration: QSFP-DD
• Fixed length and part number: 5m (16ft), QSFP-DD-400G-ACC-5M16FT
• Cable construction: Active Twinax
• Conductor specification: 28AWG
• Maximum power consumption: 2.5W Per End
• Minimum bend radius: 80mm

The rated power consumption is 2.5W 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.

The 5m (16ft) length gives QSFP-DD-400G-ACC-5M16FT more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the ACC specification and host support must still match the intended link.

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

This assembly uses 28AWG conductors, PVC jacket, minimum bend radius 80mm. 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, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with QSFP-DD-400G-ACC-5M16FT, while its mechanical assembly remains the fixed 5m (16ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

This product is ordered as QSFP-DD-400G-ACC-5M16FT in 5m (16ft). 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.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

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.
