QSFP-DD to 4x QSFP56-400G-AOC-10M33FT 400G QSFP-DD 8 x 50G PAM4 to 4 x 100G QSFP56 2 x 50G PAM4 Active Optical Breakout Cable, 10m (33ft)

This 10m (33ft) AOC cable is built for multi-vendor equipment requiring the QSFP-DD to 4x QSFP56-400G-AOC-10M33FT interface. The 400Gbps link uses QSFP-DD to 4x QSFP56 and is supplied as one complete tested assembly.

The listed modulation format is QSFP-DD-8x 50G-PAM4QSFP56-2x 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 400G Ethernet. Listed interface and protocol references include IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA, QSFP-DD-CMIS-Rev4.0, SFF-8024, IEEE 802.3bs Annex120E. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 4x 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.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

The extended 10m (33ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

QSFP-DD to 4x QSFP56-400G-AOC-10M33FT occupies the middle of this family between QSFP-DD to 4x QSFP56-400G-AOC-7M23FT at 7m (23ft) and QSFP-DD to 4x QSFP56-400G-AOC-15M49FT at 15m (49ft). It adds 3m over the shorter option for extra routing clearance, while the next longer version adds another 5m. 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 12W (QSFP-DD End)3.5W (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.

This assembly uses OFNP jacket, minimum bend radius 30mm. 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 assembly is configured for equipment that recognizes QSFP-DD to 4x QSFP56-400G-AOC-10M33FT. Before shipment, we inspect both connectors and verify identification, link establishment and optical link operation, receive activity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Quote HT part number QSFP-DD to 4x QSFP56-400G-AOC-10M33FT with the required quantity. The 10m (33ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Every QSFP-DD to 4x QSFP56-400G-AOC-10M33FT compatible assembly undergoes link testing, compatibility verification and visual inspection. The 10m (33ft) 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.
