The 2kN Fibre Optic winch is used for pulling fibre optic cable by wrapping the cable directly onto a large diameter capstan. The capstan diameter is approx. 1400mm and is of suitable diameter not to damage the fibre optic cable during the pulling process. Fibre optic winches can be set up to a maximum line pull of 2kN. However, they can be adjusted via the control console to pull line force of anything less than 2kN and have a constant line pull throughout the pulling process.
