Impact of Mode-Dependent Gain on the Capacity of Ultra-Lang-Haul SDM Systems
We review the fundamentals of MDG and its impact on the capacity of ultra-long-haul systems. We also study the impact of sub-optimal MMSE detection on system capacity. Our results dictate stringent MDG requirements for SDM amplifiers to ensure capacities equivalent to uncoupled transmission.
