Product Highlights

• Compatible alternative to Arista Networks QDD-800G-2FR4
• 800G connectivity at 850Gbps (8x 106.25Gbps)
• Optical wavelength: 1271nm, 1291nm, 1311nm and 1331nm
• Specified reach: 2km
• Dual Duplex LC/UPC / SMF interface
• Factory compatibility verification and optical performance testing before shipment

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 QSFP-DD housing alone does not make two transceiver types interoperable.

The module is programmed for equipment that recognizes the QDD-800G-2FR4 part number. Before shipment, we check EEPROM identification, link establishment and diagnostic readouts, then verify transmit and receiver performance against the stated optical specifications. Host hardware and software revisions can affect third-party module acceptance, so customers can provide the switch model and software release for a compatibility check before ordering.

Quote HT part number QDD-2FR4-800G together with OEM part number QDD-800G-2FR4 and the required quantity. Standard modules use our factory label; neutral labels, customer-branded packaging and project-specific compatibility coding are available on request. For mixed-brand installations, select the corresponding brand-specific page instead of assuming one EEPROM version fits every platform.

Each unit undergoes optical performance checks, compatibility verification and visual inspection before packing. Modules are supplied in protective blister trays or anti-static packaging and then cartoned for transport. Custom labels and project packing lists can be added for volume orders.

Standard products 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.
