We use the optical circulator to transmit and receive signals that do not interfere with each other. We can achieve a bidirectional transmission system. We use two beam splitters and four polarizers to transmit horizontal polarized light and vertical polarized light signals in free space. This paper we use the transmitted signal which is high definition multimedia interface (HDMI), analog signal (10MHz Sine wave) and digital signal (pseudorandom binary sequence, PRBS). HDMI signal use HDMI/SDI converter which convert the parallel signal to the serial signal. The serial signal will change to optical signal that is transmitted by optical transmitter. Analog signal and digital signal are modulated by electro-optics modulator. It can transmit to free space. We will discuss the impact of simultaneous bidirectional transmission and multi-user transmission.
