WAVELENGTH DIVISION MULTIPLEXING - PASSIVE OPTICAL NETWORK SYSTEM

摘要

WDM(wavelength division multiplexing)-PON(Passive Optical Network) system in which the loss according to the spectrum slicing is prevented is provided to prevent the loss by spectrum allocation by transmitting spectrum divided optical. An OLT(Optical Line Terminal)(200) is positioned in station. The optical signal is transmitted to the subscriber side. The optical signal is received from the subscriber side. A seed optical source module(100) is positioned in station. And the seed light consisting of a plurality of wavelengths in which the spectrum is divided is supplied to corresponding optical transmitters of OLT. An ONU(optical Line Unit) converts the optical signal received from OLT into the signal.
