Following are the major parameters associated with optical light receivers:-

• • 1. Minimum threshold optical power, minimum sensitivity 
    2. Responsiveness per wavelength
    3. Wavelength discrimination
    4. Receiver bit rate (max-min) 
    5. Min-max threshold level (one-zero) 
    6. Dependency on one’s density
    7. Dependence on polarisation
    8. Demodulation 
    9. Receiver noise
    10. Dependency on bias
    11. Dependency on temperature
