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

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. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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.

To order, quote QDD-SR8-800G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
