[Laser] How ??

Hello,
I know there are Optical Communications Product that can handle 10/100 Mbps
Ethernet.  Lowest price I have seen is $1700.00/Pair for 300 ft and $10,000
for long distance (1 mile ?).

I do not think these products can handle the voice channel simultaneously
however, there are boxes that can convert video/voice signal to Ethernet
packets.

Hope this helps.

Thanks 4 advise,

It has to be a data and communication-link

coud use FM-coded channels for the audio, and use ethernet (coax) for data.
(10MB network is oke).

I could use the lowband for  (spitted in a sub-transmit, and en sub-receive
band) and additional audio- speech channels in the higher band.

I'm looking for the ethernet spec's if it is possible to modulate the laser
(via a little interface and good filters)

security is a issue, that's why I don't use the LPD 430 Mhz band.

I would think so.  I saw some WiFi cards for sale at a hamfest a couple
weeks ago for $10 each.  I almost bought a couple to fool around with.

If security is a problem I'd say a digitally-modulated laser would be the
way to go.  The whole neighborhood certainly isn't going to be able to
monitor it.
