, Optical pulses using cycles per second, 1 unit of hertz = 1 cycle per second
4hz = 4 cycles per second
Definition of transmission
The movement of information in the form of electrical or optical signals from one point to
another through a transport medium
Refraction
Bending of the light as it passes from one medium into another
MHz
- Quantifies the bandwidth of a cabling system in a frequency range
- Information handling capabilities of the medium
Megabits
- transmission rate
- Number of bits information that can be transported over the medium(vehicles of the
highway)
Anatomy of a fiber
- Core
- Cladding
- Coating
Attenuation =
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] =
Light pulses traveling along fiber are subjected to loss due to absorption or scattering of
the light
Intrinsic =
Controlled by the manufacture/expresses in decibels per-kilometer impacts the signal to
reach the receiver with sufficient power
Extrinsic =
Controlled by the installer/expresses in decibels per-kilometer impacts the signal to
reach the receiver with sufficient power
Attenuation loss =
