Hi, in that case you would not need to use optical amplifiers for compensating the fiber attenuation, and since the optical amplifiers have a noise figure, your system would have better performance. Still, for a system with the same schemes (same modulation, same equalization, …) used, increasing bit rate or transmission length causes degradation of the signal to an extent depending on the system.
