EDFA Intelligent Specifications and Models
The EDFA gain spectrum is a complex function of input signal spectrum, EDFA settings, as well as multiple underlying parameters, which are generally difficult to acquire. In this section, we first describe the EDFA's underlying physics and mathematics by introducing its structure and the process of optical amplification. Due to the inaccuracy of the power monitoring process, there may be a difference between the target gain/power and the real gain/power, which can be calibrated.
