Applications
Network architects choose the 800G QSFP-DD QDD DR8 Optical Transceiver for 800G Ethernet data center and cloud network environments: it runs 850Gbps (8x 106.25Gbps) over SMF and reaches 500m. With its MTP/MPO-16 APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Compatibility with Juniper Networks systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QDD-2X400G-DR4. The link runs 8x 106.25Gb/s PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
Compliance: QSFP-DD MSA HW Rev 6.01, CMIS 5.0, IEEE 802.3cu, IEEE P802.3ck. For projects standardized on Juniper Networks hardware, this product replaces the QDD-2X400G-DR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
To order, quote QDD-DR8-800G 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.
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.
Reliability Control
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.
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.
OEM and Custom Orders
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.
