1. A fiber positioning unit of Selective Compliance Assembly Robot Arm (SCARA) type comprising an alpha and a beta mechanism; the alpha mechanism successively comprising an alpha motor, a driving shaft and a rotatable shaft, the rotation of the rotatable shaft being carried out by the alpha motor via the driving shaft; the beta mechanism comprising a beta motor and a fiber holding element that may be rotated by the beta motor; both mechanisms being mechanically connected in a way to allow a rotation of the beta mechanism by the rotatable shaft; the alpha mechanism being furthermore adapted to be partially located within a focal plate, characterized by the fact that the alpha motor is adapted to be located on one side of the focal plate while the rotatable shaft and the beta mechanism are adapted to be located mainly on an other side of the focal plate.
