The 400G QSFP-DD QDD ZR Optical Transceiver is a hot-pluggable QSFP-DD transceiver rated at 400Gbps. Using a Duplex LC/UPC optical interface over SMF at its rated wavelength, it covers transmission distances up to Amplified: ≤120km Unamplified: ≤40km. Compliance with OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018, together with integrated diagnostic monitoring, makes it a dependable choice for data center interconnect, metro transport and carrier aggregation networks.

Built for data center interconnect, metro transport and carrier aggregation networks, this QSFP-DD module carries 400Gbps over SMF up to Amplified: ≤120km Unamplified: ≤40km per link. The Duplex LC/UPC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with Juniper systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QDD-400G-ZR.

This product is designed and tested to comply with OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018. It is interoperable with Juniper equipment and serves as a direct equivalent to the Juniper part number QDD-400G-ZR.

Order this product as QDD-ZR-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

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.

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.
