[Ronja] What about using a polarizer?

[Kilian Kiekenap]

Hello,

I often thought about how to make Ronja 100mbit. I think the main problem is 
to get the nrz-code over the optical link. So I thought it would perhaps be 
possible to use two transmitters with different polarization and two 
receivers which can receive them independently. So you could get four 
different symbols.

Just a thought...
