Signal and Lane Configuration

The listed modulation format is 8x 100G-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.

Power and Thermal Planning

The rated power consumption is 14W 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.

Cable Construction and Routing

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.

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include OSFP MSA, CMIS Rev 4.0, SFF-8679, IEEE 802.3bs. Confirm that the host firmware and port configuration support the same operating mode.

Integrated Optical Assembly

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.

Length Selection and Installation Planning

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.

Position Within the Length Range

A-O800-O800-20M occupies the middle of this family between A-O800-O800-15M at 15m (49ft) and A-O800-O800-25M 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.

Arista Networks Compatibility and Factory Testing

The HT cable carries the compatibility configuration associated with A-O800-O800-20M, while its mechanical assembly remains the fixed 20m (66ft) 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.

Ordering Information

When ordering, specify A-O800-O800-20M, cable length 20m (66ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Frequently Asked Questions

Is this an original Arista Networks cable?

No. It is an HT-manufactured compatible alternative for equipment that specifies Arista Networks A-O800-O800-20M.

Can I use it between different speeds or interface types?

Only when both hosts explicitly support the same data rate, lane mapping and breakout configuration. Mechanical fit alone is not proof of interoperability.

What information should I provide for a compatibility check?

Provide the host manufacturer, equipment model, port type, hardware revision and software release, together with the OEM part number and required quantity.

Does this page include more than one cable length?

No. This page is dedicated to 20m (66ft) and part number A-O800-O800-20M. Other lengths have their own part numbers and product pages.

Quality Assurance and Packaging

Every A-O800-O800-20M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 20m (66ft) 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.

Shipping and Lead Time

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.
