APPARATUS AND METHOD FOR COMPENSATING FOR DISPERSION PROPERTY OF OPTICAL FIBER IN OPTICAL TRANSMISSION SYSTEM

摘要

The present invention discloses an apparatus and method for compensating dispersion characteristics of an optical fiber in an optical transmission system. An optical line terminal according to an embodiment of the present invention includes: a transmission unit for transmitting a first optical signal to a subscriber terminal through an optical fiber; A receiver for receiving a feedback signal related to a reception state of the first optical signal from a subscriber terminal; And a predistortion section for generating a nonlinearly modulated second optical signal based on the feedback signal.
