Applications
Network architects choose the Arista Compatible 800G QSFP-DD QDD XDR8 Optical Transceiver for 800G Ethernet data center and cloud network environments: it runs 850Gbps (8x 106.25Gbps) over SMF and reaches 2km. The Dual MTP/MPO-12 APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Arista Networks platforms and replaces the Arista Networks part QDD-800G-2XDR4 directly.

Ordering Information
Our part number for this module is QDD-XDR8-800G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Shipping and Lead Time
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
