OPTICAL COMMUNICATION DEVICE AND OPTICAL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To compensate dispersion in an optical fiber transmission path of upward and downward signals on an optical communication device side at one end according to the distance of the optical fiber between optical communication devices on both end sides.

SOLUTION: The optical communication device has: a light receiving unit 24 for converting an input light signal to a reception electric signal; a waveform monitor circuit 25 for monitoring the waveform of the reception electric signal; a first dispersion compensator 26 for reception equalizing the reception electric signal; a second dispersion compensator 21 for transmission operating the transmission electric signal; a light source 22 converting the transmission electric signal to the light signal for outputting to the optical fiber transmission path 60; and a controller 27 for controlling the first and second compensators 26, 21, based on an observation result by the waveform monitor circuit 25.
