PC TO PC FIBER OPTIC COMMUNICATION [pic] Submitted By: lex INTRODUCTION DEFINITION The project PC to PC fiber optic communication deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable
