Pre-amp EDFA ASE Noise Characterization for Optical Receiver Transmission Performance Optimization
نویسندگان
چکیده
Amplified Spontaneous Emission (ASE) noise mitigation from a pre-amp Erbium Doped Fiber Amplifier (EDFA) to the Photon Detector (PD) in optical receivers can be reduced by minimizing the EDFA ASE noise at the optical receiver level to achieve optimal optical receiver transmission performance. The photon detector used in optical receivers is either a PIN diode or an avalanche photo diode (APD). APDs have higher sensitivity than PIN diodes, but they exhibit excess noise that degrades the optical receiver transmission performance. On the other hand, PIN diodes have better noise characteristics than APDs. So, optimal optical receiver transmission performance can be obtained by using a combination of a pre-amp EDFA for good sensitivity and a PIN photon detector for low noise.
