Abstract:
The performance of an optical receiver in a digital optical communication link is studied. In the design of an optical receiver, it is vital that the module is capable of converting and shaping the optical signal while meeting or surpassing the maximum BER. Ultimately, the noise influence on the signal will determine the system sensitivity. The challenge is to find a way to determine the QoS of an optical transmission channel independent of data format and bit rate within a short time frame. The Q-factor itself significantly reduces measurement time and is thus more cost-effective. The analysis is based, assuming an input signal with impairment from factors like inter-symbol interference, jitter, and transmitter relative intensity noise.
