Optical freespace communication (OFC) means optical data transmission via an optical light ray that propagates from the transmit to the receive element of the corresponding network nodes. Transmitter and receiver must be mutually aligned.
The technology of bidirectional data transmission via POF simplex cable (see figure below)



can be transferred to an optical freespace communication system (see figure below),


with the result of a very simple to install optical freespace communication system that allows the data transmission up to distances of 50m depending on the focal length of the used ray forming elements.

For system installation the two red light rays have to be mutually aligned. This is best done during night. The optical header is a passive optical system comprising an optical lens and a glass plate protection but with no active electronic inside.
