A video coupler device capable of providing high effective electrical isolation between an analog video signal source system and a signal receiving system is disclosed. The device includes a high-speed LED and a high-speed, linear, integrated circuit. The integrated circuit includes a photodiode, an input current amplifier and an output transimpedance amplifier. The resultant video coupler exhibits a high degree of linearity and stability at a low cost, while requiring minimal external circuitry to handle standard video signals.
