In this paper, the authors propose a design of optical switching controller using FPGA for OCDMA encoder system. The encoder is one of the new technologies that use to transmit the coded data in the optical communication system by using FPGA and optical switches. It is providing a high security for data transmission due to all data will be transmitting in binary code form. The output signals from FPGA are coded with a binary code that given to an optical switch before it signal modulate with the carrier and transmit to the receiver.
