Arista Networks QSFP-400G-AO Compatible 400G QSFP112 4 x 100G PAM4 Active Optical Cable

The QSFP-400G-AO compatible cable series is intended for Arista Networks equipment requiring a 400G AOC connection. Its QSFP112 to QSFP112 configuration supports an active optical connection with permanently attached ends and fiber integrated into the assembly, while the verified source lengths listed below make length selection explicit.

AOC assemblies integrate the optical engines and fiber into a single factory-terminated link. They are useful for longer or lighter high-speed connections than copper direct attach, with no fiber polarity or connector cleaning required between separate patch cords and modules.

The QSFP112 to QSFP112 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 QSFP-400G-AO series. Before shipment, we check connector identification, link establishment and optical link operation, receive activity 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-400G-AO, the required length from 10m (33ft), 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 AOC 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.
