QSFP-DD to QSFP-DD-400G-AOC-70M230FT 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable, 70m (230ft)

QSFP-DD to QSFP-DD-400G-AOC-70M230FT 400G QSFP-DD 8 x 50G PAM4 Active Optical Cable, 70m (230ft)

For short, high-density connections, this AOC cable combines 400G performance with a fixed 70m (230ft) cable run. It corresponds to Generic QSFP-DD to QSFP-DD-400G-AOC-70M230FT and uses a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

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.

Length Selection and Installation Planning

The extended 70m (230ft) 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.

Position Within the Length Range

QSFP-DD to QSFP-DD-400G-AOC-70M230FT occupies the middle of this family between QSFP-DD to QSFP-DD-400G-AOC-50M164FT at 50m (164ft) and QSFP-DD to QSFP-DD-400G-AOC-100M328FT at 100m (328ft). It adds 20m over the shorter option for extra routing clearance, while the next longer version adds another 30m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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.

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.

Generic Compatibility and Factory Testing

For this Generic application, testing combines digital identification with actual traffic-link verification and optical link operation, receive activity and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

Ordering Information

Use part number QSFP-DD to QSFP-DD-400G-AOC-70M230FT for the 70m (230ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

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

Can the cable be folded to shorten its routing path?

No. Follow the specified minimum bend radius and route the 70m (230ft) assembly without tight folds, sharp edges or excessive cable ties.

Can I use it between different speeds or interface types?

Only when both hosts explicitly support the same data rate, lane mapping and breakout configuration. Mechanical fit alone is not proof of interoperability.

What information should I provide for a compatibility check?

Provide the host manufacturer, equipment model, port type, hardware revision and software release, together with the OEM part number and required quantity.

Quality Assurance and Packaging

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 QSFP-DD-400G-AOC-70M230FT and the 70m (230ft) length for easier inventory control.

Shipping and Lead Time

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.
