    Hi Guys,

    I need to have a 12 bit parallel image data signal converted to a serial data signal so I can send it through a fibre optic cable.

    Any good suggestion to how I might go about doing this?

    Cheers.

    With a Parallel In Serial Out (PISO) shift register.

    You can do this with most any micro-controller.

    What data rate?

    Thanks for your replies.

    MikeML > What do you mean by the data rate? The FO data rate?

    I have been looking at different micro controllers, but that's a minefield on it's own to find the right one, but I'll keep looking.

    Cheers.

    Most fiber optic communications systems run data rates > 100Mbits per s. You will be hard pressed to do more than 1Mb/s with a microcontroller. Even a parallel in/serial out shift register chips wouldn't do more than 10Mb/s. Then there is the bandwidth limitations of the LED to send, and a photodetector to receive...

    Cheers MikeML

    I hadn't thought about the FO data rate at all. I assumed that it would just feed through, whatever data signal I would feed into it.
    Any good ideas how to get around this?
    Surely it is possible to get a 12 bit video signal through fibre optic.
