TYPES OF CABLES
*use current
- Unshielded Twisted Pair (UTP) cable
- Shielded Twisted Pair (STP) cable
*use light
- Co-axial cable
- Fiber Optic cable
- Wireless cable
UNSHIELDED TWISTED PAIR (UTP) CABLE
-has 4 pairs of wires inside jacket
-each pair is twisted with different number of twists per inch
-to help eliminate interference from adjacent pairs (nearest disruption) & others electrical devices.
-UTP’s categories:
-Standard connecter : RJ-45 connecter (Registered Jack)
-Disadvantages : it may be susceptible to radio & electrical frequency interference.
SHIELDED TWISTED PAIR (STP) CABLE
-consist of two individual wires wrapped in a foil shielding
-to help provide a more reliable (no disruption/accurate) communication
-suitable for environments with electrical interference
-extra shielding can make cables quite bulking
-often used on networks using Token Ring topology
CO-AXIAL CABLE
-has a single copper conductor at its center
-a plactic layer provides insulation between center conductor & a braided metal shield
-metal shield: helps to block any outside interference from fluorescent lights, motors, and other computers
-connecter: Bayone-Neill-Concelman (BNC) connector
-different types of adapters are available for BNC connectors, including a T-connector, barrel connector, and terminator.
FIBER OPTIC CABLE
-consists of a center glass core surrounded by several layers of protective materials
-it transmits light rather than electronic signals
-able to transmit signals over much longer distances than coaxial and twisted pair
network cabling
