JNP-QSFPDD-400G-SR8 Juniper Compatible 400G QSFP-DD SR8 Transceiver

The JNP-QSFPDD-400G-SR8 is a 400G QSFP-DD optical transceiver engineered as a drop-in equivalent for Juniper platforms, programmed to the host EEPROM so it comes up as a native module with no configuration required.

This module follows Juniper's published compatibility matrix; for your exact line card or OS release, email 10.4@tenfouroptics.com and we'll confirm fit.

Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.

Short-reach multimode optics like this one live inside the data center — server-to-leaf, leaf-to-spine, and in-row links over OM3 and OM4 fiber where cost-per-port matters more than distance. It is the high-volume workhorse of east-west fabric, keeping optics cost and power low across thousands of ports in a modern build. It operates 100m.

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.

Each unit is programmed to match Juniper host values and bench-tested for traffic conformity, DOM-threshold accuracy, and optical cleanliness before it leaves the bench. Class 1 laser certified and RoHS compliant.
