Specifications

Applications and Deployment

Active copper assemblies add signal conditioning while retaining the convenience of a direct-attached cable. They are appropriate where the equipment supports the stated active-cable type and the route exceeds the practical limits of a comparable passive assembly. Per-end power, airflow and host qualification should be assessed before high-density deployment. 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 30AWG; the jacket material is PVC (OFNR); the minimum bend radius is 33mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is ≤1.8W. 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.

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, ACC construction and length-specific OEM reference together throughout that review.

Cisco 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 QSFP-4X10G-AC 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.
