The project is based on the concept of free space optical communication.
In this project, a communication between PC to PC using LASER light is established.
The project uses MAXIM Corporation’s IC MAX 232, which needs only a single power
supply of 5V (for TTL to RS-232 and vice-versa) level conversion. The comm. over the short
distance of 2-3 m is possible using IR diodes. The range could be increased up to hundred
meters, using the laser diode module in place of IR LEDs.
The laser module used is easily available as laser pointer (having about 5 mW power output).
It is to be used with its three battery cells removed and positive supply terminal soldered to
the casing and 0V point to the contact inside the laser module.


Free Space Optics (FSO) is a telecommunication technology that uses light propagating in
free space to transmit data between two points.
Free space optical communications is a line-of-sight (LOS) technology that transmits a
modulated beam of visible or infrared light through the atmosphere for broadband
communications. Free space optics uses a light emitting diode (LED) or laser (light
amplification by stimulated emission of radiation) point source for data transmission.
However, in free space optics, an energy beam is collimated and transmitted through space
rather than being guided through an optical cable.

· LAN-to-LAN connections on campuses at Fast Ethernet or Gigabit Ethernet speeds.
· LAN-to-LAN connections in a city. example, Metropolitan area network.
· To cross a public road or other barriers which the sender and receiver do not own.
· Temporary network installation (for events or other purposes).
· Reestablish high-speed connection quickly (disaster recovery).
· As an alternative or upgrade add-on to existing wireless technologies.
· As a safety add-on for important fiber connections (redundancy).

· Quick link setup
· High transmission security
· High bit rate
· Low bit error rate
· Low snow and rain impact
· Full duplex transmission
· Protocol transparency
· No interference
· Lower dispersion (compared to microwave link).
· In some devices, the beam can be visible, facilitating aiming and detection of failures.

The rs-232 port is very low speed port, how it us comparable with gigabit and microwave links?
