Applications
In 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD SR8 Optical Transceiver delivers 850Gbps (8x 106.25Gbps) transmission over twinax copper with a reach of 30m@OM3/50m@OM4. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
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.
Ordering Information
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.
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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
Shipping and Lead Time
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
