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 40km.

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.

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. Compliance documentation (RoHS declaration, IEC 60825-1 laser classification) is available on request for project quotes.
