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

It is qualified against Juniper host platforms and tested end to end so it behaves exactly as the OEM module it replaces, slotting into existing designs without surprises. The result is a like-for-like swap that protects the original network design while removing OEM-optics cost from the bill of materials. It operates in the 1550nm window.

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.

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.
