JNP-QSFPDD-400G-DR4 Juniper Compatible 400G QSFP-DD DR4 Transceiver

The JNP-QSFPDD-400G-DR4 is a 400G QSFP-DD optical transceiver engineered as a drop-in equivalent for Juniper platforms,, a like-for-like replacement that the host accepts as native, hot-swappable and ready out of the box.

• Form Factor: QSFP-DD
• Data Rate: 400G
• Protocol: DR4
• Wavelength: 1310nm
• Fiber Type: SMF
• Reach: 500m
• Connector: Duplex LC
• OEM Equivalent: JNP-QSFPDD-400G-DR4

A short single-mode optic built for intra-data-center reach, a common breakout endpoint in 100G and 400G leaf-spine designs. It lets a structured-cabling shop standardize on one fiber type end to end while still covering hall-to-hall distance. It operates 500m in the 1310nm window.

It is programmed to present native host values, so it interoperates link-to-link with OEM modules on the far end and coexists with installed optics in the same line card without compatibility flags.

We program each module to the Juniper host EEPROM and run it through traffic, DOM, and optical-cleanliness checks before it ships. Class 1 laser certified and RoHS compliant.
