Dell QDD-200G-4QPC Compatible 200G QSFP-DD 8 x 25G NRZ to 4 x 50G QSFP28 2 x 25G NRZ Passive Copper Breakout Cable

Dell QDD-200G-4QPC Compatible 200G QSFP-DD 8 x 25G NRZ to 4 x 50G QSFP28 2 x 25G NRZ Passive Copper Breakout Cable

A 200G direct-attached link depends on the correct host identity, interface mode and physical length. This page covers the Dell QDD-200G-4QPC compatible DAC series in direct-attach, including 0.5m (2ft). Each documented length-specific OEM reference is linked separately where an individual product page is available.

Applications and Deployment

Passive twinax cables are commonly selected for short switch-to-switch, switch-to-server and accelerator connections within or between nearby racks. With no separate optical conversion stage, they offer a simple low-power physical link. The assembly must nevertheless remain within the length, signaling rate and qualification limits accepted by both hosts. For this series, the listed interface is the stated interface and the aggregate rate is 200G.

Cable Construction and Routing

For this assembly, the conductor specification is 30 AWG; the jacket material is PVC; the minimum bend radius is 10mm; the operating temperature is 0 to 70°C (32 to 158°F). These parameters belong in the installation review rather than being treated as catalogue trivia. Route the cable through its intended managers without tension, avoid pressure close to the connector boots and leave enough space to operate the latches. Any service loop must respect the stated bend limit.

Mixed-Vendor Network Operation

A mixed-vendor link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether the two ends use the same compatibility requirement. The related brand links below help locate equivalent-length assemblies, while the physical form factor and lane arrangement must still agree across the complete path. For this series, keep the interface rate, DAC construction and length-specific OEM reference together throughout that review.

Dell Compatibility and Factory Testing

Testing addresses the brand-specific identification as well as the operating link and available diagnostics. The same physical cable family can require a different host identity for another equipment vendor, so the intended platform should be supplied when a deployment combines multiple brands or unusual hardware revisions. Series-level inspection is followed by the exact length and OEM configuration selected for dispatch. Functional verification includes link establishment and diagnostic indications where the host exposes them.

Ordering Information

For mixed-vendor projects, identify the equipment at both ends along with the OEM reference, length and quantity. Order each compatibility version under its own part number. If spare assemblies are required, list them separately so labels and test records remain unambiguous. For this series, follow the corresponding length link, quote that exact OEM part number and keep different lengths on separate order lines. HT part number QDD-200G-4QPC identifies the product family; the linked page provides the final length-specific identity.

Quality Assurance and Packaging

Both ends are inspected and the complete assembly is powered up for a functional check before packing. Connectors are protected individually and the cable is secured without tight bends. Optional labels can distinguish host brand, OEM reference and length for easier spares management. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.

Frequently Asked Questions

Is this an original Dell cable?

No. It is an HT-manufactured compatible cable for equipment that specifies QDD-200G-4QPC, not an original Dell-branded product.

Are different lengths and OEM part numbers separate products?

Yes. Where a length has its own OEM reference, follow the corresponding link above and order that exact part number on its own line. Do not substitute another length only because the connector arrangement is the same.

Does this DAC cable require separate modules at each end?

No. The connector ends and cable form one complete direct-attach assembly. The ends are not detachable standalone transceivers, and the complete product is tested together.

What information helps confirm compatibility?

Provide the equipment manufacturer and model, port type, hardware revision and software release, together with the required OEM reference, length and quantity. Breakout projects should also identify the intended lane configuration.
