Confirm your exact chassis, line card, and OS release against the Juniper matrix before deployment.

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

A medium-reach single-mode module tuned for the modern data center — short interconnect hops between halls and rows in high-density spine-leaf fabrics. It pairs single-mode reach with low latency and modest power for 100G-and-up east-west traffic that has outgrown multimode. It operates 2km.

Coded to the host EEPROM, it comes up as a genuine module: full diagnostic visibility, no compatibility warnings, and side-by-side operation with optics already in the chassis.

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.
