Computer to computer fiber optic communication includes the exchange of information from one PC to another PC. This makes use of the serial ports and C programming of the computers. The ports are executed in the language C. MAX 232 is utilized to transfer RS 232 logic to TTL logic and hence the circuit of optical transmitter changes the information through fiber optic cable. The optical circuit includes the LED that is suitable for MAX 232 and cable.

 Information transfer is the requirement of an hour. People are able to utilize the internet for this and yet currently it is a time consuming process. The information transfer is implemented including wireless platform and yet it is expensive affair. This is inexpensive than wireless platform and is flat in contrast to wireless platform. Fiber optics includes personal benefits, great bandwidth, large speeds etc. As a result, we should make use of optic fibers for the LANs and internet.

Under the very starting, we attempted to transfer ASCII characters among two PCs. The Conventional LAN cables are able to take the place over fiber optic cables that gave great speeds and even great data carrying capacity. The hardware is operated through the combination of software or program instructions. The user is able to use the microcontroller to solve the problems easily.


The optical receiver gets the information with the help of MAX 232 and photo transistor to change the TTL logic to RS 232 for the sequence port available at the receiving end PC. The program is done to transfer the information and is available at the serial port.
