Summary: | 碩士 === 國立虎尾科技大學 === 光電工程系光電與材料科技碩士班 === 106 === In this study, we proposed transmission architecture of bidirectional multiplexing. We use the optical circulator to transmit and receive signals that do not interfere with each other. We can achieve a bidirectional transmission system.This paper we use the transmitted signal which is high definition multimedia two-dimensional spectral amplitude coding and polarization division multiplexing based optical code-division multiple access (2D SAC/PDM-based OCDMA) was proposed for transmitting an optical-coded and polarized signal over a wireless transmission channel. 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.
