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 80km.
Because it is coded to the Juniper host platform, the switch or router reads it as a factory module — clean in diagnostics, free to mix with OEM and other compatible optics in the same chassis, and needing no firmware exceptions.
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.
