Function of the front end of an optical receiver
Fundamentally, the front-end of an optical receiver responds to an optical signal by generating a photocurrent with a photodetector. The photocurrent is then converted to a voltage. Its components can be arranged into three groups - the front end, the linear channel, and the decision circuit. The optical signal is coupled onto the photodiode by using a coupling scheme similar to that. In the intensity-modulation/direct-detection (IM-DD) system, the intensity modula-tion means that information is carried only by the intensity or power of the transmitted lightwave, not by its frequency or phase. Examples of such considerations include achieving a wide dynamic. Converting the optical energy emerging from the end of a fiber into electrical signal. various noises and distortions will unavoidably be introduced due to imperfect component responses. Its photodiode (PD) and transimpedance amplifier (TIA) can limit the throughput, determined by the noise.

Building Optical Receiver Amplification
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. 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. Booster (power) amplifiers: Boost power into transmission fiber, low NF, high Psat. In-line amplifiers: Periodically amplify signal due to fiber attenuation, high G, high Psat. An illustration of the effective gainis given below. Note the presence of a gain peak around 1530nm and a semi-flat gain. The design of an optical receiver depends on the modulation format used by the transmitter. The figure below shows a block diagram of such a receiver. Moreover, to realize a low-cost.
