Estimation of Optical Receiver Signal Parameters
Optical Receiver Calculation Example: This tool helps calculate various parameters related to optical receivers, including total link loss, received power, and power budget. A simplified Q-factor calculation is provided for illustrative purposes. The analysis is based on normal receiver sensitivity, assuming an ideal input signal with negligible impairment from factors like inter-symbol interference (ISI), rise/fall tim the bit-error ratio (BER) exceeds some specified number. Ultimately, the noise influence on the signal will determine the system sensitivity. A larger receiver sensitivity indicates poorer receiver performance.
