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.

As a parallel, multi-lane optic, this module anchors high-density spine-leaf fabrics and breakout topologies, aggregating several lanes into a single high-speed port. It is a backbone component of modern data-center and AI-cluster builds, where port density and bandwidth per rack-unit are the limiting factors. It operates 10km.

Host-programmed and qualified against Juniper platforms, it slots in beside existing OEM and third-party optics, reports clean DDM telemetry, and needs no special configuration to bring the link up.

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.
