Does system work for near IR region as well? (i.e. with centre wavelength as 850nm, 1310nm or 1550nm)

Hi Team, I am working on data transmission using Optical fibre where the center wavelength is in the near IR region. i.e. near 850nm, 1310nm or 1550nm. Kindly advise if the system can work for the light wave with centre wavelength mentioned as well.
