Hey everyone,
I was just wondering. Does anyone here know how fast a laser can pulse before it won't do it properly anymore?
I had the random idea of making a long range Ethernet bridge using lasers and receivers to act like the wires of an Ethernet cable.
And how do you go about rapidly pulsing a laser? It can't be good for the driver to constantly be shut on and off repeatedly.. Maybe I'd just ground the power line between the driver and laser so that the diode doesn't turn off but goes down in power enough that the receiver can't see it?
But if a laser can't keep up with the rate that data goes through the cable I'd just scrap the idea for a slower medium of communication.
I believe that the maximum frequency of a cat5e cable is 100MHZ.
and on a side note, which wavelength of laser goes the furthest with least power?
I'm probably not going to make anything groundbreaking with this side project but it sounds interesting
