Types of Channel

Channel

A Channel can take many forms, including ones suitable for storage which can communicate a message over time as well as space.
 A connection between initiating and terminating nodes of a circuit.
 A single path provided by a transmission medium via either physical separation, such as by multi pair cable.

Types of Channel

Fiber optic “cable”
Coaxial Cable Types
Twisted Pair

Fiber optic “cable”

● SPEED: Fiber optic networks operate at high speeds – up into the gigabits
• BANDWIDTH: large carrying capacity
• DISTANCE: Signals can be transmitted further without needing to be “refreshed” or strengthened.
• RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors or other nearby cables.
• MAINTENANCE: Fiber optic cables costs much less to maintain.

Coaxial Cable Types

 Coaxial cable, or coax, is a cable consisting of an inner conductor, surrounded by a tubular insulating layer
typically made from a flexible material, all of which is then surrounded by another conductive layer and then finally covered
again with a thin insulating layer on the outside.
 The Coaxial cable is used as a transmission line for radio frequency signals, in applications such as connecting radio transmitters and receivers with their antennas, carrying internet connections, and distributing cable television.

Twisted Pair

 A type of cable made by intertwining two separate insulated wires together.
 There are two types of twisted pair: shielded and unshielded. Shielded Twisted Pair (STP) has a fine wire mesh surrounding the wires to protect the transmission;
 Unshielded Twisted Pair (UTP) does not. Shielded cable is used in older telephone networks, network, and data communications to reduce outside interference.
