The 800G QSFP-DD QDD DR8 Optical Transceiver is a QSFP-DD optical transceiver delivering 850Gbps (8x 106.25Gbps) over SMF. Operating at 1310nm with a MTP/MPO-16 APC interface, it reaches 500m and is compliant with QSFP-DD MSA HW Rev 6.01, CMIS 5.0, IEEE 802.3cu, IEEE P802.3ck. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in 800G Ethernet data center and cloud network environments.

The 800G QSFP-DD QDD DR8 Optical Transceiver is used in 800G Ethernet data center and cloud network environments, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 500m. The MTP/MPO-16 APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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.

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.

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.

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.

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.

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.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
