Signal and Lane Configuration

The listed modulation format is SFP-DD-2x 50G-PAM4 QSFP28-4x 25G-NRZ. 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.

Position Within the Length Range

SFP-DD to QSFP28-100G-AOC-20M66FT occupies the middle of this family between SFP-DD to QSFP28-100G-AOC-15M49FT at 15m (49ft) and SFP-DD to QSFP28-100G-AOC-30M98FT at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 10m. 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 SFP-DD: <3.5WQSFP28: <5.5W. 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 100GBASE SR2 Ethernet. Listed interface and protocol references include SFP-DD & QSFP28 MSA, IEEE 802.3cd, RoHS6 (Lead-free). 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

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.

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 SFP-DD to QSFP28-100G-AOC-20M66FT for the 20m (66ft) 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 20m (66ft) 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

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Shipping and Lead Time

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
