Specifications

Signal and Lane Configuration

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.

Cable Construction and Routing

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.

Network and Protocol Considerations

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.

Breakout Port Mapping

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.

Integrated Optical Assembly

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.

Length Selection and Installation Planning

Choose QSFP-DD to 2x QSFP56-400G-AOC-10M33FT when the measured managed path justifies 10m (33ft), not simply to leave a large spare coil. Additional reach can simplify adjacent-rack routing, yet unused cable still needs bend-safe storage and ventilation clearance. Keep identification visible so this extended version is not confused with shorter spares. Within this family, QSFP-DD to 2x QSFP56-400G-AOC-7M23FT is shorter at 7m (23ft), while QSFP-DD to 2x QSFP56-400G-AOC-15M49FT is the next longer choice at 15m (49ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

QSFP-DD to 2x QSFP56-400G-AOC-10M33FT occupies the middle of this family between QSFP-DD to 2x QSFP56-400G-AOC-7M23FT at 7m (23ft) and QSFP-DD to 2x 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.

Project Documentation and Cable Identification

Large deployments are easier to audit when the order code, physical length and endpoint record agree. Keep the OEM reference in the compatibility document and use the HT part number on the packing list. Where several lengths arrive together, labels and carton groups can be arranged by rack or port plan so installers do not have to identify cables by appearance alone. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 12W (QSFP-DD End)5.5W (QSFP56 Per End); the jacket material is OFNP.

Power and Thermal Planning

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.

Generic Compatibility and Factory Testing

Factory verification links the compatibility identity to the exact physical assembly described on this page. Identification, connector condition and live link behavior are checked before packing. Customers can submit equipment and firmware details with the project documentation for a more specific pre-order compatibility review. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.

Frequently Asked Questions

Ordering Information

Use the listed HT part number for ordering and retain the OEM reference as the host-compatibility cross-reference. Send quantities by length, along with any rack-based packing or label instructions. If the project has mixed equipment, include the host model for each group rather than relying only on the aggregate cable rate. Keep QSFP-DD to 2x QSFP56-400G-AOC-10M33FT associated with 10m (33ft) throughout the order and receiving record.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.

Quality Assurance and Packaging

Inspection and link testing are completed before the cable enters its protective packaging. Project orders can be packed and labelled by length, rack or customer reference, with packing documentation that makes received quantities straightforward to reconcile against the installation schedule. Neutral packaging and customer-specific packing documentation are available on request.
