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 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.
