QSFP-DD to 4x QSFP56-400G-AOC-3M10FT 400G QSFP-DD 8 x 50G PAM4 to 4 x 100G QSFP56 2 x 50G PAM4 Active Optical Breakout Cable, 3m (10ft)

Designed for hosts that recognize QSFP-DD to 4x QSFP56-400G-AOC-3M10FT, this QSFP-DD to 4x QSFP56 cable delivers 400G transmission over a fixed 3m (10ft) assembly. Its AOC construction provides a factory-terminated active optical link with the optical engines and fiber integrated into the 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 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 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.

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 4x QSFP56-400G-AOC-3M10FT occupies the middle of this family between QSFP-DD to 4x QSFP56-400G-AOC-2M7FT at 2m (7ft) and QSFP-DD to 4x QSFP56-400G-AOC-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.

The assembly is configured for equipment that recognizes QSFP-DD to 4x QSFP56-400G-AOC-3M10FT. 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.

This product is ordered as QSFP-DD to 4x QSFP56-400G-AOC-3M10FT in 3m (10ft). 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.

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.

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.
