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

The QSFP-DD to QSFP-DD-400G-AOC-7M23FT cable on this page is the 7m (23ft) version for Generic hosts requiring 400G operation. Its QSFP-DD to QSFP-DD AOC construction reduces the connection to one factory-terminated assembly. Related lengths, brand cross-references and rack-integration notes support a precise high-density deployment.

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.

Network and Protocol Considerations

The intended application is 8x 50G-PAM4. Listed interface and protocol references include IEEE 802.3cd, OIF-CEI-04.0, QSFP-DD MSA,QSFP-DD-CMIS-rev4p0. Confirm that the host firmware and port configuration support the same operating mode.

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

This 7m (23ft) assembly is intended for routes that shorter members of the same family cannot serve comfortably. Before ordering, document the actual pathway and the space available for service access. During installation, secure the integrated optical cable and both optical engines without compressing it into an undersized bundle or leaving its weight suspended from the ports. Within this family, QSFP-DD to QSFP-DD-400G-AOC-5M16FT is shorter at 5m (16ft), while QSFP-DD to QSFP-DD-400G-AOC-10M33FT is the next longer choice at 10m (33ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

QSFP-DD to QSFP-DD-400G-AOC-7M23FT occupies the middle of this family between QSFP-DD to QSFP-DD-400G-AOC-5M16FT at 5m (16ft) and QSFP-DD to QSFP-DD-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.

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 8W Per End; the jacket material is OFNP.

Power and Thermal Planning

The rated power consumption is 8W 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.

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.

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. Quantity and any labeling instructions should be attached specifically to QSFP-DD to QSFP-DD-400G-AOC-7M23FT.

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.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

No. It is manufactured by HT under our own manufacturer identity.

Can different brands be connected with the same assembly?

Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.

Does this order code cover multiple lengths?

No. QSFP-DD to QSFP-DD-400G-AOC-7M23FT refers here to 7m (23ft). Every other verified length has a separate part number and page in the length list.

Are separate transceivers or patch leads required?

No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.

Shipping and Lead Time

Available stock is normally prepared for dispatch within one to three working days, while larger production requirements are scheduled with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
