The Arista Compatible 800G QSFP-DD QDD XDR8 Optical Transceiver is a QSFP-DD optical transceiver delivering 850Gbps (8x 106.25Gbps) over SMF. Operating at 1310nm with a Dual MTP/MPO-12 APC interface, it reaches 2km and is compliant with QSFP-DD MSA HW Rev 7.0, CMIS Rev 5.0, IEEE802.3cu-2021, IEEE802.3ck-2022. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in 800G Ethernet data center and cloud network environments.

Product Highlights

• QSFP-DD form factor, 850Gbps (8x 106.25Gbps) data rate
• Wavelength: 1310nm
• Connector: Dual MTP/MPO-12 APC
• Reach: up to 2km
• Fiber media: SMF

The Arista Compatible 800G QSFP-DD QDD XDR8 Optical Transceiver is used in 800G Ethernet data center and cloud network environments, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 2km. With its Dual MTP/MPO-12 APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Compatibility with Arista Networks systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QDD-800G-2XDR4. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

On the compatibility side, this unit is the practical equivalent of the Arista Networks part QDD-800G-2XDR4 and works in Arista Networks systems out of the box. Standards compliance covers QSFP-DD MSA HW Rev 7.0, CMIS Rev 5.0, IEEE802.3cu-2021, IEEE802.3ck-2022.

To order, quote QDD-XDR8-800G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
