1 Network Cables By Brandon O

2 Types of Cables Twisted-Pair Unshielded twisted-pair (UTP)
Shielded twisted-pair (STP) Fiber-Optic Cable

3 Twisted-Pair 2 insulated copper wires Twisted around each other
Reduces crosstalk, EM, and RFI

4 UTP (Unshielded twisted-pair)
Two-Four pairs of wires Cancellation effect Reduces EM and RFI interference

5 UTP categories Categories are based on Category 3 Category 5 or 5e
Number of wires in the cable Number of twists in those wires Category 3 used in telephone systems Four wire pairs 10 Mbps Category 5 or 5e 100 Mbps 5e has extra twists Category 6 Plastic dividers to separate wires More twists than 5e

6 Shielded twisted-pair (STP)
Each pair is wrapped in a metallic foil All wires are then put in a metallic braid or foil

7 Coaxial Cable Copper-cored cable Has heavy shielding
Used to connect to networks

8 Types of Coaxial Cables
Thicknet or 10BASE5 used in networks 10 Mbps speed maximum length of 500 m ( ft). Thinnet 10BASE2 10 Mbps maximum length of 185 m (607 ft). RG-59 – Most commonly used for cable television in the U.S. RG-6 – Higher quality cable than RG-59, with more bandwidth and less susceptibility to interference.

9 Fiber-Optic Cable Made of Glass or plastic
Transmits information using light Is not effected by EM or RFI

10 Types of Fiber-Optic Cables
Multimode thicker core easier to make can use simpler light sources (LEDs) works well over distances of a few kilometers or less Single-mode very thin core harder to make uses lasers as a light source transmit signals dozens of kilometers with ease
