Consider the simplified receiver chain shown in Figure 1. The RF line up consists of a low noise amplifier (LNA) and two gain blocks (RF Amp #1 and RF Amp #2). The finite bandwidth and …
WebMay 7, 2024 · Gain flatness is particularly important when many EDFAs are concatenated in an optical transmission line (e.g. submarine optical transmission), as the gain variation is accumulated in the EDFA chains and results in large signal power differences between the WDM channels. Gain flatness can be improved by, for example, modification of glass ... WebGain Flatness measurement. The gain flatness or gain response is the measurement of the gain variation at different frequency of operation of the RF systems such as RF Transceiver, RF Power amplifier etc. Gain …

As the WDM channels traverse multiple EDFAs in a transmission system, the … WebGain flatness should be +/- 1.5 dB across the entire band. Ripple is another specification closely related to band flatness. Ripple is the peak-to-peak variation of the signal over a narrow portion of the band, say 10 MHz. Good ripple specs are in the order of +/- 0.1 dB over any 10 MHz. 9. External Reference vs. Phase-Locked Loop (PLL)
