Answer:
Wavelength Mismatch
Explanation:
Optical fiber cables are used because they have lowest attenuation(loss of signal strength).
Attenuation is directly proportional to wavelength.
According to me this issue is most likely caused by Wavelength mismatch.If the wavelength of the signal is high then there is more attenuation in that signal.
