@theruran LED based open source optical transceivers, ( http://ronja.twibright.com ) they have implemented a custom 10BASE-T PHY with discrete analog components that works perfectly and garantees no backdoors.
Doing so, they kept up with their goals of full user control over the hardware, and extrem simplicity.
Such approach is way much harder for 100BASE-T* links, and I think to be considered impossible for 1000BASE-TX.
@stman hey - have you seen the Koruza project? it's another FOSS FSO system 😛
