At single-mode reach this module bridges the middle ground — access to aggregation, building-to-building campus links, and short data-center interconnect spans that outrun multimode but never need amplification. The single-mode path keeps the signal clean across the full distance over existing OS1 and OS2 plant. It operates 10km in the 1310nm window.

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.

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.
