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.

Product Highlights

The Arista Compatible 400G QSFP-DD QDD SR8 Optical Transceiver is used in 400G Ethernet data center and cloud network environments, where it provides a 400Gbps link over MMF up to 70m@OM3/100m@OM4. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with Arista Networks platforms and replaces the Arista Networks part QDD-400G-SR8 directly. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

On the compatibility side, this unit is the practical equivalent of the Arista Networks part QDD-400G-SR8 and works in Arista Networks systems out of the box. Standards compliance covers QSFP-DD MSA, CMIS 4.0, IEEE 802.3cd.

Order this product as QDD-SR8-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.

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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

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.
