The invented optical cross connection points device relates to the optical cross connection points structure of the optical network. The structure includes the P line routes for inputting signals to the kernel exchanging and processing part, the P lines routes for outputting signals from the kernel exchanging and processing part. Each signal input route consists of one optical preamplification (OPA), one optical demultiplexer unit (ODU). Each signal output route consists of the variable optical attenuator (OPA), one optical multiplexer unit (OMU) and one optical power amplifier. The inventionprovides the following functions. The upper and lower routes of arbitrary wavelength get to the pointed ports; complete conversion of the part of wavelengths; limited broadcast and electricity regeneration of the part of wavelengths.
