The listed modulation format is QSFP-DD-8x 50G-PAM4QSFP56-4x 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 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.

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 20m (66ft) 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 2x QSFP56-400G-AOC-20M66FT occupies the middle of this family between QSFP-DD to 2x QSFP56-400G-AOC-15M49FT at 15m (49ft) and QSFP-DD to 2x QSFP56-400G-AOC-25M82FT at 25m (82ft). It adds 5m 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)5.5W (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 determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3cd, IEEE 802.3bs, QSFP-DD MSA, SFF-8024, SFF-8679, SFF-8665, CMIS 4.0, OIF-CEI-04.0. 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-AOC-20M66FT, while its mechanical assembly remains the fixed 20m (66ft) 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 to 2x QSFP56-400G-AOC-20M66FT in 20m (66ft). 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.

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.
