TOPIC 2.1.4 CABLE USED IN ETHERNET NETWOK. FIBER OPTIC CABLING AND ITS MAIN ADVANTAGE OVER OTHER MEDIA.
Properties of Fiber Optic Cabling 
Fiber Media Cable Design
1.Jacker
1) PVC jacket that protects the fiber against abrasion and moisture.
2) Can vary depending on the cable usage
2.Strengthening Material
1) the fiber cable from being stretched when it is being pulled.
2) Material used is often the same material used to produce bulletproof vests.
-
- Cladding
1) from slightly different chemicals than those used to created the core.
2) it tends to act like a mirror by reflecting light back into the core of the fiber.
3) keep light in the core as it travels down the fiber.
- Core
1) the light transmissions elements at the center of the optical fiber.
2) typically silica / glass
3) light pulses travel through the fiber core.

Characteristics of Copper Cabling
Copper Media
- conducts electrical signals very well but it has its limitation
- data travels on copper cables as small pulse of electrical voltage cause it easily distorted by outs noise and signal attenuation
- cable type with shielding or twisting of the pairs of
wires are designed to minimize signal degradation
UTP
- used in Ethernet LAN
- eight wires twisted into four color-coded pairs and then
wound inside a cable jacket
- colored pairs identify the wires for proper connection at
the terminals
