PRODUCT DETAILS

Features and applications

QDD-400G-ZR — interface and application

Juniper QDD-400G-ZR identifies the exact optical transceiver under review. Its electrical or optical interface, environmental limits and host software requirements should be reviewed together.

  • The QSFP-DD interface is specified for 400 Gigabit Ethernet, 4 x 100 Gigabit Ethernet. Confirm the required operating mode on both ends of the link.
  • The connection uses Duplex LC PC/UPC. Include the connector polish and cable arrangement in the installation review.
  • The listed interface standard is IEEE 802.3-2018; a matching mechanical connector alone does not establish interoperability.

Installation and compatibility checks

  • Match the connector, fiber type and applicable reach specification to the cable plant.
  • Check the link power budget and receiver limits; distance alone does not confirm a working optical link.
  • Confirm host port support, lane mode, software release and operating temperature before ordering.
  • Review the feature license together with the coherent optic. QDD-4C-ZR-P-B is the license-inclusive order code listed for this model.
  • Reach depends on the link design: less than 120 km on amplified DWDM links limited by noise, or less than 40 km on unamplified single-wavelength links limited by loss. Confirm the full optical budget before ordering.
