A take up apparatus for drawn optical fiber comprises: a take-up stand supporting a first, storage bobbin about a first axis ; a motor for rotating this first bobbin about that axis; a supporting means supporting a second, sampler bobbin about a second, different axis ; a second motor for rotating this second bobbin about the second axis; and means for controlling the relative rates of rotation provided by the motors. In use drawn fiber is guided about the first bobbin to the second bobbin and the bobbins are rotated to wind the fiber about the first bobbin and onto the second bobbin during initial drawing of the fiber. Subsequently the fiber between the bobbins is cut and the drawn fiber is wound onto the first bobbin.
