Here is some testing report video of my automatically OpAmp gain switching depending on recieved laser signal with InGaAs photodiode. 

Led switching indicate gain mux switching position. 

On LCD display you can see sfp module TX power, InGaAs Photodiode RX power, sfp module temperature and voltage. And the last line indicate mux switching position number. 

I2c driver little helped me with some different SFP modules:)
