Signal and Lane Configuration

The listed modulation format is 4x 25G-NRZ to 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.

Cable Construction and Routing

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 44.5mm. 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 100G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFF-8665. Confirm that the host firmware and port configuration support the same operating mode.

Passive Copper Operation

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

Length Selection and Installation Planning

The extended 9m (29ft) 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 DAC construction avoids a chain of separate modules and patch leads.

Position Within the Length Range

QSFP28 to QSFP28-100G-DAC-9M29FT is the longest of 2 verified length options in this family. Compared with QSFP28 to QSFP28-100G-DAC-7M23FT at 7m (23ft), it provides 2m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

Power and Thermal Planning

The rated power consumption is 1.5W. 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.

Generic Compatibility and Factory Testing

The HT cable carries the compatibility configuration associated with QSFP28 to QSFP28-100G-DAC-9M29FT, while its mechanical assembly remains the fixed 9m (29ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

Ordering Information

This product is ordered as QSFP28 to QSFP28-100G-DAC-9M29FT in 9m (29ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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 9m (29ft) 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, QSFP28 to QSFP28-100G-DAC-9M29FT and the 9m (29ft) 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.
