800G QSFP-DD QDD SR8 Optical Transceiver

Designed for 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD SR8 Optical Transceiver provides 850Gbps (8x 106.25Gbps) throughput in a QSFP-DD form factor. It operates at 850nm over fiber through a MTP/MPO-16 APC connector and supports link lengths up to 30m@OM3/50m@OM4. The module meets QSFP-DD MSA Hardware Rev 7.0, CMIS Rev 5.0, IEEE 802.3df-2024, IEEE 802.3df-2024 and includes digital diagnostic monitoring for live status readout.

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

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. With its MTP/MPO-16 APC optical interface, the module works directly with the twinax copper infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. 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.

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.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.

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.
