Flex-Span single jacket designs are optimised for a broader combination of fibre counts and span lengths, providing ADSS system designers with more flexibility in their product selection. As its name indicates, there is no support or messenger wire required, so installation is achieved in a single pass. Flex-Span ADSS includes fibre counts up to 144 optical fibres and any type or combination of single-mode or multi-mode fibres within the cable. Pole-to-pole span lengths range from 50ft. to over 1,000ft.
