Cisco QSFP-4SFP25G-AOC Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Optical Breakout Cable

Use this AOC cable where a 100G link is required between compatible QSFP28 to 4x SFP28 ports. This HT version corresponds to Cisco QSFP-4SFP25G-AOC and covers 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft), 30m (98ft) and 50m (164ft); electrical or optical construction follows the AOC specification rather than a detachable transceiver-and-patch-cord arrangement.

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 QSFP28 to 4x SFP28 interface and 100G 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-4SFP25G-AOC 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.

This series is ordered by the base HT part number QSFP-4SFP25G-AOC plus length and compatibility requirement. Available source configurations documented on this page are 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft), 30m (98ft) and 50m (164ft); other lengths can be discussed with the factory with each length-specific OEM reference reviewed under its own product configuration.

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.
