Applications
Built for data center interconnect, metro transport and carrier aggregation networks, this QSFP-DD module carries 850Gbps (8x 106.25Gbps) over SMF up to Amplified: ≤120km Unamplified: ≤44km per link. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA Rev 6.3, IEEE 802.3-2022, OIF 800ZR, CMIS 5.2. It plugs into any standards-based QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Order this product as QDD-ZR-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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
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.
