Fig. 2: Performance of spatial transmission over a long time in unstabilized MMFs.

Averaged transmission accuracy over time and accuracy spatial distribution of MMDN and static network are compared on four configurations with decreasing instability: a spatial resolution: 32 × 32, fiber length: 1 km; b spatial resolution: 16 × 16, fiber length: 1 km; c spatial resolution: 32 × 32, fiber length: 100 m; d spatial resolution: 16 × 16, fiber length: 100 m.
