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. With its Dual MTP/MPO-12 APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Arista Networks platforms and replaces the Arista Networks part QDD-800G-2XDR4 directly. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
Compliance: QSFP-DD MSA HW Rev 7.0, CMIS Rev 5.0, IEEE802.3cu-2021, IEEE802.3ck-2022. For projects standardized on Arista Networks hardware, this product replaces the QDD-800G-2XDR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
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.
