Applications
Built for 800G Ethernet data center and cloud network environments, this QSFP-DD module carries 850Gbps (8x 106.25Gbps) over twinax copper up to 30m@OM3/50m@OM4 per link. With its MTP/MPO-16 APC optical interface, the module works directly with the twinax copper infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
Standards compliance covers QSFP-DD MSA Hardware Rev 7.0, CMIS Rev 5.0, IEEE 802.3df-2024, IEEE 802.3df-2024. The unit works in any equipment with a standard QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
Order this product as QDD-SR8-800G. 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.
Quality and Testing
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.
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
