Juniper QDD-400G-ZRA Compatible 400G QSFP-DD ZR 80km SMF Transceiver Module

Metro and inter-site spans that need 400G to travel 80km over single-mode fiber sit squarely in ZR territory, and the QDD-400G-ZRA is a Juniper-compatible QSFP-DD built for exactly those links. It operates within the 191.3-196.1 THz range listed for the part, terminates in LC/UPC, carries Juniper host coding from the factory, and reports its optical state over DDM/DOM once the port is up.

• Data Rate: 400G
• Fiber Type: SMF
• Reach: 80km
• Connector: LC/UPC

The module is built against the published MSA and each unit is validated — coding, diagnostics, transmit performance — before dispatch. Slotted into a Juniper chassis it assumes the OEM designation directly, keeping the 80km span's design untouched. This module is covered by the GreenLights4Life® 5-Year Replacement Warranty.
