ABSTRACT:
A method of determining estimates of fiber loss and return signal power for an optical fiber from a return signal uses a polynomial fit with data samples representing the return signal. From the polynomial fit an estimated fiber loss value is determined. The estimated return signal power is computed using a function of the estimated fiber loss value.
