PRODUCT DETAILS
Features and applications
QDD-400G-FR4 — interface and application
Juniper QDD-400G-FR4 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. Confirm the required operating mode on both ends of the link.
- The listed reach is 2 km using SMF. Use the specification table to check any separate fiber grades or operating standards.
- The connection uses Duplex LC PC/UPC. Include the connector polish and cable arrangement in the installation review.
- The listed interface standard is 400G-FR4 and 400GBASE-FR4; 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.
