The type direction transmission signal distribution method in the passive optical net system, the bureau side device and the member house side device

摘要

Signal to noise (signal-to-noise ratio) easily it can design ratio the type direction transmission signal distribution method in the passive optical net system, in regard to the bureau side device and the member house side device, the expensive light amplifier is made unnecessary, also distribution with the electric information offers easy type direction transmission signal distribution method. The bureau side device (OLT) with the bit interleaving multiplexing section 1-11 of the 1-1, it descends and the bit multiplexes the main signal data of the digital signal and the passive optical net system of the type direction transmission signal only of direction and transmits, with the bit separated section 1-21 of the member house side device 1-2, descends and bit separates converts the main signal data of the digital signal and the passive optical net system of the type direction transmission signal only of direction, descends and extracts the type direction transmission signal only of direction, processes the image signal of the type direction transmission signal with the image signal processing unit 1-22.
