Arista Networks OSFP-800G-2OPC Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top to 2 x 400G OSFP 4 x 100G PAM4 IHS/Finned Top Passive Copper Breakout Cable
A 800G direct-attached link depends on the correct host identity, interface mode and physical length. This page covers the Arista Networks OSFP-800G-2OPC compatible DAC series in 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top), including 1.5m (5ft). Each documented length-specific OEM reference is linked separately where an individual product page is available.

Field Installation and Maintenance
Inspect the route and both connectors before installation, then support the cable without pulling on either connector housing. During maintenance, release the latch properly rather than using the cable as a handle. Keep protection on unused ends, and if the assembly is removed for later use, coil it loosely and record its part number so the same length can be returned to service. For this series, keep the interface rate, DAC construction and length-specific OEM reference together throughout that review.
Applications and Deployment
A passive DAC reduces the connection to one factory-terminated electrical assembly. This is useful where low latency, low interface power and a short managed route matter more than optical reach. Cable gauge, connector construction and host port settings still influence whether the complete link operates reliably. For this series, the listed interface is 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) and the aggregate rate is 800G.
Cable Construction and Routing
The specification table records the conductor specification is 28AWG; the jacket material is PVC; the minimum bend radius is 40.5mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is 0.1W (800G End)0.1W (400G 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.
Quality Assurance and Packaging
The cable and both connectors are inspected before a functional link test. Connector protection and bend-safe packing reduce handling damage during transport and storage. Customer or site labels can be added for field inventories, with different lengths separated to simplify issue and return of spare assemblies. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.
Arista Networks Compatibility and Factory Testing
A field-ready cable needs both correct identification and a stable operating link. Our pre-packing check therefore includes the connectors, host recognition and link behavior. For equipment with uncertain revision history, providing the host model and software release helps identify compatibility requirements before the assembly reaches the installation site. 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.
Ordering Information
Request the cable by its exact part number and length, and state the equipment model if compatibility confirmation is needed. Site orders can list quantities by rack or installation team. Any requested label should retain the part number so a removed or spare cable can still be identified accurately. 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 OSFP-800G-2OPC identifies the product family; the linked page provides the final length-specific identity.
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 OSFP-800G-2OPC, 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.
Does this DAC cable require separate modules at each end?
No. The connector ends and cable form one complete direct-attach assembly. The ends are not detachable standalone transceivers, and the complete product is tested together.
What information helps confirm compatibility?
Provide the equipment manufacturer and model, port type, hardware revision and software release, together with the required OEM reference, length and quantity. Breakout projects should also identify the intended lane configuration.
