Hi,
I'm new to hardware designs with fibre optics. My application is
relative simple, I want to network embedded processors using fibre
optics as physical layer. At the moment I'm using RS232 for point to
point connections. To increase the data-rate and to have better
protection against EMI interference, I want to replace the electrical
wires with optical fibres.
My application is point to point. The data-rate is not fixed yet,
however it should be somewhere between 25 and 150Mb/s. Therefore,
plastic fibres should be sufficient. At the moment I'm struggling to
find appropriate interface chips which provide the UART or NIC
functionality for fibre optics on one side and a microcontoller
interface at the other. Here is a small block diagram:
MC <-> NIC <<->> EO <=> EO <<->>NIC <-> MC
where
MC microcontroller
<-> Microcontroller interface (SPI, Parallel, ...)
NIC gluelogic
<<->> Electrical interface
EO electrical to optical transceiver
<=> fibre optics.
Here are my questions:
Where can I find more information about interfacing microcontroller to
fibre optics?
What are appropriate glue logic chips which provide the `NIC'
functionality?
Thank you for your help in advance.
