●● Attenuation =
Answer: The decrease in magnitude of transmission signal strength
between points, expressed in decibel as the ratio of out put to input
signal
●● Attenuation [insertion loss] =
Answer: Light pulses traveling along fiber are subjected to loss due to
absorption or scattering of the light
