In term of networking,guided media is any device which connects the nodes for the purpose of communication. There are three main types of wired media in use:
Co-axial cable: They contain Shielding. They are of two types:
- Thin net: They are used in transmitting the data along short distance.
- Thick net: They are used in transmitting the data along long distance.
Twisted Pair: Here, the wire is twisted over each to ensure interference immunity and low radiation emission. They are of two types.
- Shielded twisted pair: These cable possess high security but are of high price.
- Unshielded twisted pair: These are the most popular cable in today’s networking because of its excellent price/quality ratio.
Fiber Optic Cable: These cables provide broad bandwidth and high noise immunity. They are of two types:
- Single mode: It works with laser-based emitters. It spans the longest distance. It is expansive in compare to multi-mode.
- Multi-mode: It works with light emitting diodes (LEDs) and spans the shorter distance. It is less expansive in compare to single mode.
