Does increasing the length of the fiber optic cable affect the signal
Attenuation is the progressive loss of signal strength that occurs as light travels through the fiber. This is measured in decibels per kilometer (dB/km), with lower numbers indicating better performance. Are the ends of all cables cut and polished with the same precision and quality? What about repeatability of those measurements? I'm not going to delete my answer, but do consider accepting. To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission.
