The 800G QSFP-DD QDD SR8 Optical Transceiver is a hot-pluggable QSFP-DD transceiver rated at 850Gbps (8x 106.25Gbps). Using a MTP/MPO-16 APC optical interface over fiber at 850nm, it covers transmission distances up to 30m@OM3/50m@OM4. Compliance with QSFP-DD MSA Hardware Rev 7.0, CMIS Rev 5.0, IEEE 802.3df-2024, IEEE 802.3df-2024, together with integrated diagnostic monitoring, makes it a dependable choice for 800G Ethernet data center and cloud network environments.

Product Highlights

• QSFP-DD form factor, 850Gbps (8x 106.25Gbps) data rate
• Wavelength: 850nm
• Connector: MTP/MPO-16 APC
• Reach: up to 30m@OM3/50m@OM4

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. 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 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.

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.

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.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.
