In the GYFTY cable, single-mode/multimode fibres are positioned in the loose tubes,
which are made of high modulus plastic materials, while the loose tubes strand together around
non-metallic central strength member (FRP) into a compact and circular cable core.
For certain high fibre count cables, the strength member would be covered with polyethylene (PE).
The water-blocking materials are distributed into the interstices of the cable core.Then the cable is completed with a PE sheath.
