Arista Networks LPO-800G-2DR4 Compatible 800G Twin-port OSFP IHS/Closed Finned Top Transceiver Module
Built for hosts recognizing LPO-800G-2DR4, this HT-manufactured Twin-port OSFP IHS/Closed Finned Top module delivers 800G transmission at 1310nm. Its rated reach is 500m, with Dual MTP/MPO-12 APC as the physical interface. The specifications and engineering guidance below support procurement teams match an equipment parts list to a clearly defined optical product, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design
Use this module for equipment interconnection over the specified single-mode fiber plant, including enterprise backbone, campus, metro or data-center interconnect links according to its rated distance. Confirm that both ends use the same optical standard and wavelength plan, and allow for connector, splice and patch-panel loss within the stated power budget.
Before deployment, check the host port type, supported data rate and firmware requirements. The 800G interface configuration must match the remote equipment; sharing a Twin-port OSFP IHS/Closed Finned Top housing alone does not make two transceiver types interoperable.
The single-mode link budget should include fiber attenuation, connectors, splices and panels over the intended 500m route. Keep the Dual MTP/MPO-12 APC interface clean and match the remote optical standard. Consider receiver overload as well as insufficient power on short links.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -2.9~4.0dBm; the stated optical power budget is 3.0dB. During commissioning, record the host diagnostic readings after the link has stabilized and compare them with those limits. DOM values are useful operational indicators, but they do not replace calibrated optical measurements when a link is marginal. Investigate unexpected loss through connector inspection, cleaning and a channel measurement before replacing the module. Diagnostic monitoring is listed as Supported. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.
Procurement and Asset Identification
A useful purchase order identifies the host platform, expected OEM code and optical standard separately. This prevents a module with the same housing but another wavelength, reach or identification profile from being substituted. For mixed deployments, keep one order line per OEM reference and reconcile each received unit with its intended port. For this model, the principal parameters are data rate 850Gbps (8x 106.25Gbps), wavelength 1310nm, rated reach 500m.
Arista Networks Compatibility and Factory Testing
Compatibility testing for LPO-800G-2DR4 combines identification with a live link and available transmit, receive and alarm information. Connector condition is inspected separately. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Ordering Information
Quote HT part number OSFP-2DR4-800G-LPO together with OEM reference LPO-800G-2DR4 and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Quality Assurance and Packaging
Each LPO-800G-2DR4 compatible module is inspected, powered up and functionally checked before protective packing. Dust caps and individual trays shield the interface during transport. Customer references, rack groups and project packing lists can be added for volume orders.
Frequently Asked Questions
Is this an original Arista Networks transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies LPO-800G-2DR4, not an original Arista Networks-branded module.
Which fiber and connector are required?
Use Dual MTP/MPO-12 APC with SMF. The specified maximum reach is 500m, subject to fiber quality and total link loss.
Can it be mixed with another wavelength or reach version?
Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
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.
