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 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.
Before shipment every module is coded to the host platform, then verified for protocol conformity, diagnostic accuracy, and end-face cleanliness. Class 1 laser certified, RoHS compliant.
