Definition of transmission - (correct Answer) - The movement of information in the form of electrical or
optical signals from one point to another through a transport medium
Refraction - (correct Answer) - Bending of the light as it passes from one medium into another
MHz - (correct Answer) - - Quantifies the bandwidth of a cabling system in a frequency range
- Information handling capabilities of the medium
Megabits - (correct Answer) - - transmission rate
, - Number of bits information that can be transported over the medium(vehicles of the highway)
Anatomy of a fiber - (correct Answer) - - Core
- Cladding
- Coating
Attenuation = - (correct 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] = - (correct Answer) - Light pulses traveling along fiber are subjected to loss
due to absorption or scattering of the light
Intrinsic = - (correct Answer) - Controlled by the manufacture/expresses in decibels per-kilometer
impacts the signal to reach the receiver with sufficient power
Extrinsic = - (correct Answer) - Controlled by the installer/expresses in decibels per-kilometer impacts the
signal to reach the receiver with sufficient power
Attenuation loss = - (correct Answer) - - Expressed in decibels per kilometers
- Impacts the ability of the signal to reach the receiver with sufficient power
dBm = - (correct Answer) - Optical power referred to as 1 milliwatt of power
