There's no error corrections though, no encoding, just plain old OOK. At the receiver the output is fed to a string of inverters to clean it up. As long as you have a solid strong signal this works. How fast you can get it going would depend on your receiver bandwidth and max laser modulation rate or the frequency responce of whole system - plus how your programs can handle any errors if they happen.

Yes I had been playing with building a high speed link to do some testing
back before I lost my job. After loosing my job, I am so busy trying to make
enough money doing different jobs that I only have time to read the mail
and comment every once in a while.

Would be neat to have a device that can do a reasonable data stream
then you hook a computer to each end and send any mode you want.
