QSFP-DD to 2x QSFP56-400G-ACC-3M10FT 400G QSFP-DD 8 x 50G PAM4 to 2 x 200G QSFP56 4 x 50G PAM4 Active Copper Breakout Cable, 3m (10ft)

The HT-manufactured QSFP-DD to 2x QSFP56-400G-ACC-3M10FT compatible cable provides 400G connectivity for multi-vendor equipment. This 3m (10ft) version is an actively conditioned copper link for the stated high-speed interface, with an exact part number and length that can be matched directly to the equipment requirement.

OEM Part Number: QSFP-DD to 2x QSFP56-400G-ACC-3M10FTHT Part Number: QSFP-DD to 2x QSFP56-400G-ACC-3M10FT

Product Highlights

• 400G connectivity at 400Gbps
• Interface configuration: QSFP-DD to 2x QSFP56
• Fixed length and part number: 3m (10ft), QSFP-DD to 2x QSFP56-400G-ACC-3M10FT
• Cable construction: Active
• Conductor specification: 30AWG
• Maximum power consumption: 1.45W（QSFP-DD End） 0.62W（QSFP56 Per End）
• Minimum bend radius: 70mm

The rated power consumption is 1.45W（QSFP-DD End） 0.62W（QSFP56 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 QSFP-DD to 2x QSFP56 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

QSFP-DD to 2x QSFP56-400G-ACC-3M10FT occupies the middle of this family between QSFP-DD to 2x QSFP56-400G-ACC-2M7FT at 2m (7ft) and QSFP-DD to 2x QSFP56-400G-ACC-5M16FT at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

This assembly uses 30AWG conductors, PVC jacket, minimum bend radius 70mm. 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, SFF-8679. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with QSFP-DD to 2x QSFP56-400G-ACC-3M10FT, while its mechanical assembly remains the fixed 3m (10ft) 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.

Use part number QSFP-DD to 2x QSFP56-400G-ACC-3M10FT for the 3m (10ft) 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.

Every QSFP-DD to 2x QSFP56-400G-ACC-3M10FT compatible assembly undergoes link testing, compatibility verification and visual inspection. The 3m (10ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

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.
