Applications
Network architects choose the 800G QSFP-DD QDD SR8 Optical Transceiver for 800G Ethernet data center and cloud network environments: it runs 850Gbps (8x 106.25Gbps) over twinax copper and reaches 30m@OM3/50m@OM4. The MTP/MPO-16 APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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
This product is designed and tested to comply with QSFP-DD MSA Hardware Rev 7.0, CMIS Rev 5.0, IEEE 802.3df-2024, IEEE 802.3df-2024. 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
Our part number for this module is QDD-SR8-800G. 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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
