A fiber measurement system for obtaining a fiber bending loss data of a moving fiber when compared with a static fiber is provided. The system includes an optical transmitter for generating a first optical modulating signal, a first optical coupling device electrically connected to the optical transmitter for coupling the first optical modulating signal from the static fiber to the moving fiber, a perturbing device electrically connected to the first optical coupling device for modulating the first optical modulating signal of the moving fiber to a second optical modulating signal, a second optical coupling device electrically connected to the perturbing device for coupling the second optical modulating signal from the moving fiber to the static fiber, an optical receiver electrically connected to the second optical coupling device for reading the second optical modulating signal, and a filter electrically connected to the optical receiver for filtering the second optical modulating signal, thereby obtaining the fiber bending loss data. |
