PUNO scratch-resistant mating surfacesThe Hardened Lens Contact (PUNO) process is a patented termination procedure that yields significant benefits in endface durability and overall optical performance. In the place of the typical scribe step in fiber termination, We uses a CO2 laser to traverse the entire mating surface. This process changes the physical characteristics of the glass and creates an integrated lens at the mating surface.Durability: The PUNO laser process changes the physical properties of the glass at the endface to create a surface that is harder and smoother than before. These changes create a mating surface that is scratch resistant and will withstand a higher number of mates relative to standard connectors. Extensive testing has proven PUNO connectors do not degrade in performance over the course of 1000 mates.Performance: The integrated lens formed by the PUNO laser process creates a connector that consistently performs at reference grade levels. Both SM and MM terminations yield best in class IL and ORL, and have reference grade endface geometry as well (GR-326 compliant). All PUNO terminations are fully interoperable with standard / existing terminations and will increase the performance of any application.For additional information on PUNO Technology, consider referencing the embedded video below and any of the following links:PUNO White PaperPUNO Technical PaperPUNO PresentationPUNO Products
