Network access
Copper Cable
-
Data travels on copper cables as small pulses of electrical voltage cause it easily distorted by outside noise and signal attenuation
Cable type with shielding or twisting of the pairs of wires are designed to minimize signal degradation
-

-
STP cable
The outer insulating jacket contains an inner braided copper mesh to shield the pairs of twisted cables, which themselves are wrapped in foil.

-
-
color coded plastic insulation - electrically isolates wire from each other and identifies each pair
-
-
UTP testing parameter: Wire map, cable length, signal loss due to attenuation, crosstalk
Jacket
Typically a PVC jacket that protects the fiber against anion mot, and other contaminants This outer jacket composition can vary depending on the cable usage
Strengthening Material
Surround the buffer prevents the berate from being stretched when it is being pulled The motorland on the same material used to produce bulletproof vest
-
Cladding
Made from sightly different chemicals than those used to create the core t tends to act ke minor by reflecting light back Into the core of the fiber This keops light in the core as It travels down the fiber
Core
The core is actually the light transmission element on at the center of the optical fiber. This core is typically silica or glass Light puses travel through the fiber core

Allows greater dispersion and therefore, loss of signal
Suited for long distance applications, but shorter than single mode
