QSFP-DD to 8x SFP28-200G-DAC-1M3FT 200G QSFP-DD 8 x 25G NRZ to 8 x 25G SFP28 25G NRZ Passive Copper Breakout Cable, 1m (3ft)

QSFP-DD to 8x SFP28-200G-DAC-1M3FT 200G QSFP-DD 8 x 25G NRZ to 8 x 25G SFP28 25G NRZ Passive Copper Breakout Cable, 1m (3ft)

For short, high-density connections, this DAC cable combines 200G performance with a fixed 1m (3ft) cable run. It corresponds to Generic QSFP-DD to 8x SFP28-200G-DAC-1M3FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

Signal and Lane Configuration

The listed modulation format is QSFP-DD-8x 25G-NRZSFP28-25G-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.

Breakout Port Mapping

The QSFP-DD to 8x SFP28 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.

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

At 1m (3ft), QSFP-DD to 8x SFP28-200G-DAC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

Position Within the Length Range

QSFP-DD to 8x SFP28-200G-DAC-1M3FT occupies the middle of this family between QSFP-DD to 8x SFP28-200G-DAC-0.5M2FT at 0.5m (2ft) and QSFP-DD to 8x SFP28-200G-DAC-1.5M5FT at 1.5m (5ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. 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 0.1W (QSFP-DD End)0.1W (SFP28 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 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 20.5mm. 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 determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA, SFF-8432, IEEE 802.3bs-200GAUI-8, IEEE802.3by-25GAUI, CMIS 4.0, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

Generic Compatibility and Factory Testing

Each QSFP-DD to 8x SFP28-200G-DAC-1M3FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

Ordering Information

Use part number QSFP-DD to 8x SFP28-200G-DAC-1M3FT for the 1m (3ft) 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 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.

Does this page include more than one cable length?

No. This page is dedicated to 1m (3ft) and part number QSFP-DD to 8x SFP28-200G-DAC-1M3FT. Other lengths have their own part numbers and product pages.

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

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.
