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 cost much less to maintain.
Coaxial Cable
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, networks, and data communications to reduce outside interference.
