Passive DAC assemblies are normally used for short switch-to-switch, switch-to-server and rack-adjacent links. They draw very little power and avoid separate optical components, but the selected length must remain within the host and cable specification.

The the stated connector configuration interface and 25G data rate must match the equipment at both ends. The source application is listed as 25G Ethernet, Data Center, 5G Wireless. 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 CAB-S-S-25G 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.

This series is ordered by the base HT part number CAB-S-S-25G plus length and compatibility requirement. Available source configurations documented on this page are 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 4m (13ft) and 5m (16ft); other lengths can be discussed with the factory with each length-specific OEM reference reviewed under its own product configuration.

Every DAC 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.
