Applications
In 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD DR8 Optical Transceiver delivers 850Gbps (8x 106.25Gbps) transmission over SMF with a reach of 500m. With its MTP/MPO-16 APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Juniper Networks platforms and replaces the Juniper Networks part QDD-2X400G-DR4 directly. The link runs 8x 106.25Gb/s PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Juniper Networks part QDD-2X400G-DR4 and works in Juniper Networks systems out of the box. Standards compliance covers QSFP-DD MSA HW Rev 6.01, CMIS 5.0, IEEE 802.3cu, IEEE P802.3ck.
Ordering Information
Our part number for this module is QDD-DR8-800G. 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.
Our Testing Process
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.
How We Pack
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.
Factory Custom Capability
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.
Logistics
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.
