A method for tensioning and positioning a fiber optic cable includes providing and securing a first portion of the fiber optic cable in a first support with a first clamp. A second portion of the fiber optic cable is then provided in a second support, and secured thereto with a second clamp. A cam contacting the second support is then rotated, thereby rotating the second support due to its weight and the weight of the second clamp. The rotation of the second support creates a gravity-assisted moment arm that uniformly and repeatably tensions and positions the fiber optic cable. After the fiber optic cable is uniformly tensioned and positioned, a refractive-index grating may be etched in the glass optical fiber portion of the cable. Once the grating is etched, the cable may be removed by reversing the method.
