Abstract

In this study, we present and demonstrate a 10 Gbit/s on-off keying (OOK) free space optical communication (FSO) system with signal security operation by using polarization-multiplexing method. A single wavelength can be separated two orthogonal polarization FSO signals, which mean the FSO_p and FSO_s respectively, by using two polarizers with mutually orthogonal polarization directions. And the FSO_p and FSO_s wavelengths can act as the data and interference channels for FSO connection. When the injected power of FSO_s is >−30 dBm, the FSO_p signal will be interfered seriously for security protection. In addition, the FSO signal can pass through 25 km fiber link and support 1000 m free space transmission length.
