Thanks,i've a fiber optica diode PIN (epitaxx epm718) but i can't find
a good circuit for capture the current modulation,now i've the best
result with connect the katode to the oscilloscope probe and the anode
to the oscilloscope ground.I must use ,to see something,a 2mV/div step
in my scope.Can anyone hel me ?I need a bandwith of 10Mhz.
thanks matteo

Get an app note from UDT Sensors. Their web page
(http://www.udt.com/products.html) lists the app note but does not
allow you to download it. I guess you'll have to fill out their
inquiry form.
