Optical Fiber Signals

[saymeng]

Hi,

Can a full duplex optic fiber be use to handle multiple signals at the same time? I am trying to use them for MCU to IGBT Driver board.

Thank you

Well, your certainly can multiplex multiple signals on a optic fiber, but why do you need it to be duplex?

Hi crutschow,

You are correct, my mistake, I am kind of new to this. I will read up on Multiplexers.

Thank you

What is the data frequency you need to send?

Hi Crutschow,

The PWM frequency range is 8 to 12KHz. The main reason I am considering optical fiber link is due to EMI.

Thank you

Are you controlling more than one IGBT. If so, is that 8 to 12kHz for each IGBT independently.
