Microcables are fiber optic cables characterized by high density. The bend-optimized fibers of microcables are more insensitive to bending than classic opticalfibers and have a diameter of only 200 µm compared to 250 µm of conventional glass fibers.
As a result, microcables are much more compact and can be packaged with a much higher packing density in the FO cable. The higher packing density means that loose tubes with 144 glass fibers are only about half as thick as conventional loose tubes: Namely, 8 mm instead of 15 to 16 mm. This means that considerably more optical fibers can be accommodated in the same space.
Microcables are available as FO indoor cables and FO outdoor cables. Due to their small diameter, they can be laid flexibly and can also be installed using the blow-in technique.
