The basic optical receiver consists of a photodetector to convert the optical signal into a current, a low-noise preamplifier to convert and amplify the current into a voltage, an optional low pass filter to shape the received pulse or limit the bandwidth and a high-gain.

Optical Detectors-PIN diode and APD diodes –Photo detector noise, SNR, –Comparison of Photo detectors – Fundamental Receiver Operation – Design of Analog Systems- Design of Digital Systems. An additional layer is added in which secondary electron-hole pairs are generated through impact ionization. They consist of a transmitter on one end of a fiber and a receiver on the other end. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. Among various optical module form factors, SFP (Small Form-Factor Pluggable).
