A typical Fiber Optic Receiver Circuit interfacing the PIN Photodiode

to a Philips NE52121 transimpedance amplifier (140MHz) and to

the Philips NE5211 FDDI Fiber Optic Postamplifier. This design is

capable of operating at 125Mbps with single +5 or -5.2V supply

with differential output impedance of 100k.
