NOISE SUPPRESSION APPARATUS FOR INJECTION SEEDED OPTICAL SOURCE AND WAVELENGTH DIVISION MULTIPLEXED-PASSIVE OPTICAL NETWORK SYSTEM HAVING THE SAME

摘要

Disclosed are a noise suppressing apparatus for an injection seeded optical source and a WDM-PON system including the same. The noise suppressing apparatus according to one embodiment of the present invention efficiently suppresses noises by a feed-forward method by controlling a gain of an amplifier according to the level of data used in modulation.
