This 1G single-mode optic covers campus backbones and metro access runs, the dependable choice for linking distributed sites and aggregation switches over existing single-mode fiber. Where multimode tops out, it extends gigabit reach across the campus without touching the host or the cabling plan. It operates 2km.

Coded to the host EEPROM, it comes up as a genuine module: full diagnostic visibility, no compatibility warnings, and side-by-side operation with optics already in the chassis.

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.

Backed by the GreenLights4Life® lifetime warranty — buy it once, covered forever. In stock and ships same or next business day.
