Arista AOC-O-O-400G-20M Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top Ethernet Active Optical Cable, 20m (66ft)

This HT cable matches the AOC-O-O-400G-20M requirement for Arista equipment. The 20m (66ft) assembly supports 400G operation and provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly; its complete electrical and mechanical details are listed below.

The listed modulation format is 8x 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.

The intended application is 400G Ethernet. Listed interface and protocol references include CMIS V4.0, OSFP MSA. Confirm that the host firmware and port configuration support the same operating mode.

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 20m (66ft) 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.

AOC-O-O-400G-20M occupies the middle of this family between AOC-O-O-400G-15M at 15m (49ft) and AOC-O-O-400G-25M at 25m (82ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The rated power consumption is 10W 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.

Each AOC-O-O-400G-20M compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe optical link operation, receive activity and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Arista platform should be included with the order.

Use part number AOC-O-O-400G-20M for the 20m (66ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, AOC-O-O-400G-20M and the 20m (66ft) length for easier inventory control.

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.
