Leveraging a custom simulation framework in OptiSystem, we evaluate gain, noise figure, Q-factor, and bit error rate (BER) across 1535–1560 THz and fiber lengths of 0–50 meters. The Ho:Yb configuration demonstrates unparalleled performance, achieving a peak gain of 0 dB, a noise figure of 5 dB, and an ultralow BER of <10^(-14), attributed to efficient energy transfer between Ho3+ and Yb3+ ions. In contrast, (Ho + Tm) exhibits suboptimal gain (−0.5 dB) and elevated noise (6 dB) due to spectral mismatches, while (Yb + Tm) offers moderate stability for medium-haul applications. By correlating dopant interactions with performance metrics, this work establishes (Ho + Yb) as the optimal choice for high-speed, long-distance networks, addressing critical gaps in hybrid amplifier design.
