QSFP-DD to 4x QSFP56-400G-AOC-7M23FT 400G QSFP-DD 8 x 50G PAM4 to 4 x 100G QSFP56 2 x 50G PAM4 Active Optical Breakout Cable, 7m (23ft)

The QSFP-DD to 4x QSFP56-400G-AOC-7M23FT cable offers a direct QSFP-DD to 4x QSFP56 connection at 400Gbps. Its 7m (23ft) length and AOC construction are intended for multi-vendor equipment, with no separate transceiver-and-patch-cord assembly required.

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 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 7m (23ft) 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-7M23FT occupies the middle of this family between QSFP-DD to 4x QSFP56-400G-AOC-5M16FT at 5m (16ft) and QSFP-DD to 4x QSFP56-400G-AOC-10M33FT at 10m (33ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 3m. 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 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.

Compatibility is more than matching the QSFP-DD to 4x QSFP56 shape. This assembly is prepared for hosts expecting QSFP-DD to 4x QSFP56-400G-AOC-7M23FT and is checked for identification, stable link behavior and optical link operation, receive activity and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Quote HT part number QSFP-DD to 4x QSFP56-400G-AOC-7M23FT with the required quantity. The 7m (23ft) 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.

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 4x QSFP56-400G-AOC-7M23FT and the 7m (23ft) length for easier inventory control.

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.
