Dell QSFP-40G-1SPC Compatible 40G QSFP+ to 1 x 10G SFP+ Passive Copper Cable
A 40G direct-attached link depends on the correct host identity, interface mode and physical length. This page covers the Dell QSFP-40G-1SPC compatible DAC series in QSFP+ to SFP+, including 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). 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 QSFP+ to SFP+ and the aggregate rate is 40G.
Cable Construction and Routing
The specification table records the conductor specification is 26AWG; the jacket material is PVC (OFNR); the minimum bend radius is 28mm; the operating temperature is 0℃ to 70℃ (32 to 158°F); the power consumption is 0.1W Per End. Use those values when preparing the rack pathway and receiving checklist. Do not pull a connector by its cable, compress the run under tight ties or force excess length into a sharp coil. Connector protection should remain in place until the assembly is ready for insertion.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. For this series, keep the interface rate, DAC construction and length-specific OEM reference together throughout that review.
Dell Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. 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 a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. 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 QSFP-40G-1SPC identifies the product family; the linked page provides the final length-specific identity.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. 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 QSFP-40G-1SPC, 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.
