“…Note that CWDM is presently considered an unamplified technology due to the unavailability of optical amplifiers that can operate over the entire CWDM optical band (e.g., 1271-1611 nm) [2]. Although several promising wideband hybrid amplifiers have been demonstrated in the literature, their costly designs have impeded their commercial development [3][4][5][6][7][8][9][10][11][12]. Several amplified PON architectures have been proposed and implemented, with the main goal to increase the reach of networks [13][14][15].…”

We describe the mathematical model and present simulation results for the optimization of a hybrid Raman/optical parametric amplifier (HROPA), exhibiting a bandwidth of 170 nm and low ripple that covers the top half of the wavelength plan (e.g., 1441 to 1611 nm) of next generation coarse wavelength division multiplexed passive optical network systems. We show that a critical parameter in the proper amplifier parameter optimization is the inclusion of the fourth-order dispersion coefficient (β(4)). Omission of β(4) can lead to over-estimation or underestimation of the gain bandwidth, and hence its inclusion in the analysis of the HROPA is necessary.
