Abstract: New, robust flexible ribbon designs with fiber counts other than traditional 12f flexible ribbon designs are introduced. Ribbon designs with fiber counts of 16 and 24 are introduced which allow very high fiber density cables combined with the capability for mass fusion splicing. These added ribbon designs allow improved ribbon and cable compatibility with alternative network configurations. This ribbon structure variants are evaluated for robustness, splice compatibility, and attenuation performance during long term aging and environmental exposure.
