ACC assemblies use active copper signal conditioning to extend practical copper-link reach while retaining a direct-attach installation. They suit high-density switch and accelerator connections where the host supports the stated active-cable type and power requirement.

The QSFP+ to SFP+ interface and 40G data rate must match the equipment at both ends. For breakout versions, confirm the lane mapping and the speed of every downstream port; matching connector shapes alone does not establish interoperability.

The assembly is configured for equipment that recognizes the QSFP-4X10G-AC series. Before shipment, we check connector identification, link establishment and electrical link stability, signal integrity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the switch, server or accelerator model and software release for a pre-order compatibility review.

Quote HT part number QSFP-4X10G-AC, the required length from 1m (3ft), 3m (10ft), 5m (16ft), 7m (23ft) and 9m (29ft), and the OEM part number used by your equipment. The length-specific OEM identifiers above link to their own product pages so each reference can be ordered separately.

Every ACC assembly undergoes continuity and link testing, compatibility verification and a visual inspection of both connector ends. Cables are coiled without exceeding their minimum bend radius, fitted with connector protection and packed in anti-static bags or protective trays before cartoning. Project labels and packing lists are available for volume orders.

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.
