Arista Networks A-D400-2Q200-30M Compatible 400G QSFP-DD 8 x 50G PAM4 to 2 x 200G QSFP56 4 x 50G PAM4 Active Optical Breakout Cable, 30m (98ft)

For short, high-density connections, this AOC cable combines 400G performance with a fixed 30m (98ft) cable run. It corresponds to Arista Networks A-D400-2Q200-30M and uses a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

The listed modulation format is QSFP-DD-8x 50G-PAM4QSFP56-4x 50G-PAM4. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

A-D400-2Q200-30M is the longest of 10 verified length options in this family. Compared with A-D400-2Q200-25M at 25m (82ft), it provides 5m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

The rated power consumption is 12W (QSFP-DD End)5.5W (QSFP56 Per End). Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses OFNP jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include IEEE 802.3cd, IEEE 802.3bs, QSFP-DD MSA, SFF-8024, SFF-8679, SFF-8665, CMIS 4.0, OIF-CEI-04.0. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 2x QSFP56 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

The extended 30m (98ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

The HT cable carries the compatibility configuration associated with A-D400-2Q200-30M, while its mechanical assembly remains the fixed 30m (98ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Arista Networks software can request a pre-order check.

This product is ordered as A-D400-2Q200-30M in 30m (98ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Every A-D400-2Q200-30M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 30m (98ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
