A photodiode (PD) senses the light arriving through a fiber and gener-ates a proportional current. The TIA then converts this current to voltage and applies the result to a limit-ing amplifier.
The influence of TIA-PD wire length and TIA π π΄πΊπΆ parameter on the sensitivity of optical module is realized, and the problem of sensitivity optimization of optical module is solved.
