NVIDIA/Mellanox OSFP-800G-2OPC Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top to 2 x 400G OSFP 4 x 100G PAM4 IHS/Finned Top Ethernet Passive Copper Breakout Cable

Use this DAC cable where a 800G link is required between compatible 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) ports. This HT version corresponds to NVIDIA/Mellanox OSFP-800G-2OPC and covers 1.5m (5ft); 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 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) interface and 800G 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 OSFP-800G-2OPC 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 OSFP-800G-2OPC, the required length from 1.5m (5ft), and the OEM part number used by your equipment. The length-specific OEM identifiers above identify the exact product configurations so each reference can be reviewed and ordered separately.

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.
