I thought about using fiber modules. I was/am worried that they would
not work well due to packaging (and im not to hot on cutting one up
just yet). Having never used one in this way, Does the packaging need
to be modifide or is there one that is already in shape for this type
of project? Using a photo diode would be fine if I could find one that
I knew of one that would work well. Yes ive hit google but find little
in the way of user experiance for the units I found. Ive not yet
settled on a exact wavelength. If using fiber modules it will have to
be around 850nm, 1300nm and 1550nm as that is what all the units ive
seen operate in. If using a photodiode then likely around 750 to 900nm
as most of the IR leds ive seen are in this range. I should check the
fiber modules and see if the respond to this range also. I wonder if
it possible to couple FSO into a fiber? This project is for `just` 1/4
mile links. A few friends and I want to build a 10 or 100mbit ethernet
ring between our homes.
