Arista Networks C-Q200-4S50 Compatible 200G QSFP56 4 x 50G PAM4 to 4 x 50G SFP56 50G PAM4 Passive Copper Breakout Cable

Use this DAC cable where a 200G link is required between compatible QSFP56 to 4x SFP56 ports. This HT version corresponds to Arista Networks C-Q200-4S50 and covers 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft); electrical or optical construction follows the DAC specification rather than a detachable transceiver-and-patch-cord arrangement.

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 QSFP56 to 4x SFP56 interface and 200G 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 C-Q200-4S50 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 C-Q200-4S50 plus length and compatibility requirement. Available source configurations documented on this page are 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft); 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.
