Specifications

Signal and Lane Configuration

The listed modulation format is 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 QSFP-DD MSA, SFP56 MSA, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

Breakout Port Mapping

The QSFP-DD to 8x 50G SFP56 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

The extended 10m (33ft) configuration gives QSFP-DD to 8x 50G SFP56-400G-AOC-10M33FT a specific place in the family reach range. It should not be treated as a universal substitute for every shorter order code. Match it to a documented route, protect the integrated optical cable and both optical engines during handling and retain the part-number label for later maintenance. Within this family, QSFP-DD to 8x 50G SFP56-400G-AOC-7M23FT is shorter at 7m (23ft), while QSFP-DD to 8x 50G SFP56-400G-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 8x 50G SFP56-400G-AOC-10M33FT occupies the middle of this family between QSFP-DD to 8x 50G SFP56-400G-AOC-7M23FT at 7m (23ft) and QSFP-DD to 8x 50G SFP56-400G-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.

High-Density Rack Integration

In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the minimum bend radius is 30mm; the stated power consumption is 10W (QSFP-DD End) 3W (SFP56 Per End); the jacket material is OFNP.

Power and Thermal Planning

The rated power consumption is 10W (QSFP-DD End) 3W (SFP56 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.

Quality Assurance and Packaging

Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Neutral packaging and customer-specific packing documentation are available on request.

Ordering Information

Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. This page’s fixed configuration is 10m (33ft); another length must be quoted under its corresponding part number.

Generic Compatibility and Factory Testing

The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.
