Abstract
A CCTV camera 32 monitors the sag of a loop of optical fiber 11 extending between a drawing mechanism 12 and a takeup spool 18. The camera is rotated 90.degree. about its optical axis so as to vertically scan the plane of the fiber catenary and forward the video scan signal to a video signal processor 28. The processor continuously determines the displacement of the lowest point of the loop from an optimum position and generates an electrical signal proportional thereto. The signal is forwarded to a spooling motor 19 to adjust the speed of the takeup spool to cause the fiber catenary to return to a predetermined position.
