10/100BASE-T SFPArista Networks A-O800-O800 Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top Active Optical Cable
A 800G direct-attached link depends on the correct host identity, interface mode and physical length. This page covers the Arista Networks A-O800-O800 compatible AOC series in OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top), including 1m (3ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft), 25m (82ft), 30m (98ft) and 50m (164ft). Each documented length-specific OEM reference is linked separately where an individual product page is available.

Applications and Deployment
An AOC removes the separate module-and-fiber interfaces from a high-speed connection. Both optical ends remain attached to the cable, simplifying polarity control and connector handling. Host identification, wavelength plan, aggregate rate and any breakout configuration must still agree across the link. For this series, the listed interface is OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) and the aggregate rate is 800G.
Quality Assurance and Packaging
Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.
Cable Construction and Routing
The specification table records the jacket material is OFNP; the minimum bend radius is 30mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is 14W Per End. Use those values when preparing the rack pathway and receiving checklist. Do not pull a connector by its cable, compress the run under tight ties or force excess length into a sharp coil. Connector protection should remain in place until the assembly is ready for insertion.
High-Density Rack Integration
In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this series, keep the interface rate, AOC construction and length-specific OEM reference together throughout that review.
Ordering Information
Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. For this series, follow the corresponding length link, quote that exact OEM part number and keep different lengths on separate order lines. HT part number A-O800-O800 identifies the product family; the linked page provides the final length-specific identity.
Arista Networks Compatibility and Factory Testing
The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Series-level inspection is followed by the exact length and OEM configuration selected for dispatch. Functional verification includes link establishment and diagnostic indications where the host exposes them.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
Frequently Asked Questions
Is this an original Arista Networks cable?
No. It is an HT-manufactured compatible cable for equipment that specifies A-O800-O800, not an original Arista Networks-branded product.
Are different lengths and OEM part numbers separate products?
Yes. Where a length has its own OEM reference, follow the corresponding link above and order that exact part number on its own line. Do not substitute another length only because the connector arrangement is the same.
