400G QSFP-DD QDD ZR Optical Transceiver

Designed for data center interconnect, metro transport and carrier aggregation networks, the 400G QSFP-DD QDD ZR Optical Transceiver provides 400Gbps throughput in a QSFP-DD form factor. It operates at its rated wavelength over SMF through a Duplex LC/UPC connector and supports link lengths up to Amplified: ≤120km Unamplified: ≤40km. The module meets OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018 and includes digital diagnostic monitoring for live status readout.

Network architects choose the 400G QSFP-DD QDD ZR Optical Transceiver for data center interconnect, metro transport and carrier aggregation networks: it runs 400Gbps over SMF and reaches Amplified: ≤120km Unamplified: ≤40km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on Juniper hardware, it is a drop-in equivalent of the QDD-400G-ZR.

On the compatibility side, this unit is the practical equivalent of the Juniper part QDD-400G-ZR and works in Juniper systems out of the box. Standards compliance covers OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018.

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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

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.

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.

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.
