Lesson 4 – Network Connectors and Wiring Standards

• Coaxial Cable

• Twisted Pair Cable

• Fiber Optic Cable

• Practical Video: Twisted Pair – UTP – CAT 6 cable

• Wiring Standards – Cross and Straight cable

Coaxial Cable• also referred as coax,

• contains a center conductor made of copper that’s surround by a plastic jacket, with a

braided shield over it.

• requires Male and Female BNC (Bayonet Neill–Concelman) connectors.

• Typically used in cable television, cable modems.

Twisted-Pair Cable• consists of eight individually insulated wires that are twisted together in pairs.

• Sometimes a metallic shield is placed around them, called as Shielded Twisted-Pair

(STP).

• Cable without outer shielding is called Unshielded Twisted-Pair (UTP).

• Example: CAT 1, 2, 3, 4, 5, 5e, 6. • Requires RJ-45 connectors.

Fiber Optic Cable• transmits digital signals using light impulses rather than electricity.

• allows light impulses to be carried on either a glass or a plastic core.

• Single-mode fiber (SMF) and Multi-mode fiber (MMF) are its types.

• Requires ST (Straight Tip) or SC (Subscriber Connector) as connectors.
