Opsistor transmitter data compression system

An optoelectronic coupler, for coupling a source of light signals to a receiver that can process voltage-phase signals, comprising:

• a light transmitter capable of generating light signals of first and second bandwidths;
• a switch receiver having at least one pair of first and second photodiodes;
• a first conductor electrically connecting the anode of the first photodiode to the cathode of the second photodiode;
• a second conductor electrically connecting the cathode of the first photodiode to the anode of the second photodiode;
• a first light filter disposed on the photoactive surface of the first photodiode that allows the first bandwidth of light to pass;
• a second light filter disposed on the photoactive surface of the second photodiode that allows the second bandwidth of light to pass, whereby the light transmitter signals utilizing the first and second bandwidths can be converted into voltage-phase signals across the first and second conductors;
• a modulated signal generator for sending data signals to the said optoelectronic coupler's two-wavelength light transmitter for transmission to the photodiodes, the data signals being modulated in a plurality of master profiles and subprofiles with different cycle time variations;
• a signal receiver for receiving and decoding the voltage-phase signal from the said optoelectronic coupler's two-wavelength optoelectronic switch receiver.
