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.

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.

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.
