NVIDIA/Mellanox OSFPFL-400G-PC Compatible 400G OSFP 4 x 100G PAM4 RHS/Flat Top InfiniBand NDR Passive Copper Twinax Cable

The OSFPFL-400G-PC compatible cable series is intended for NVIDIA/Mellanox equipment requiring a 400G DAC connection. Its OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) configuration supports a passive copper twinax connection without separate optical modules or fiber patch cords, while the verified source lengths listed below make length selection explicit.

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 OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) interface and 400G 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 OSFPFL-400G-PC 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.

When ordering, specify OSFPFL-400G-PC, the host platform and one of the covered configurations: 0.5m (2ft). If your purchase documentation uses any of the listed OEM part numbers, include that identifier as well so our team can verify the intended version before production.

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.
