Arista Compatible 400G QSFP-DD QDD SR8 Optical Transceiver

Designed for 400G Ethernet data center and cloud network environments, the Arista Compatible 400G QSFP-DD QDD SR8 Optical Transceiver provides 400Gbps throughput in a QSFP-DD form factor. It operates at 850nm over MMF through a MPO-16/APC connector and supports link lengths up to 70m@OM3/100m@OM4. The module meets QSFP-DD MSA, CMIS 4.0, IEEE 802.3cd and includes digital diagnostic monitoring for live status readout.

In 400G Ethernet data center and cloud network environments, the Arista Compatible 400G QSFP-DD QDD SR8 Optical Transceiver delivers 400Gbps transmission over MMF with a reach of 70m@OM3/100m@OM4. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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-400G-SR8. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: QSFP-DD MSA, CMIS 4.0, IEEE 802.3cd. For projects standardized on Arista Networks hardware, this product replaces the QDD-400G-SR8 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.

Our part number for this module is QDD-SR8-400G. 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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

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.

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.

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.
