High-precision fiber gyroscopes commonly use 1550nm wavelength erbium-doped fiber light sources, which have better spectral symmetry and are less affected by environmental temperature changes and pump power fluctuations. Additionally, their lower self-coherence and shorter coherence length effectively reduce the phase error of fiber gyroscopes.
