ABSTRACT:
A measuring system operated by an optical transmitter; an optical spectrum analyzing part receiving an input optical signal branched from the optical transmitter; an optical receiver for connecting with, via an optical fiber to be measured, the optical transmitter; and a data processing part operative to produce a chromatic dispersion coefficient to be measured, by comparing a calculated baseband characteristic, derived from data concerning the optical transmitter and the optical spectrum analyzing part, with an actual baseband characteristic obtained in the optical receiver.
