Cables

There are different types of cables designed for specific requirements-

Coaxial cables:

The Coaxial cable is a common Communication cable widely used in cable TVs.

The inner wire is a Standard Straight Wire.

Coaxial Cables Uses:

Coaxial Cable is Used as a Transmission line for Radio frequency Signals. Its applications include feedlines connecting Radio Transmitters And receivers to their antennas. As well as Computer networks (e.g. Ethernet) Connections and Digital Audio as well as Distribution of cable Television Signals.

Twisted Pair cables:

The Twisted is a pair of wires insulated as well as twisted together to reduce crosstalk.

In addition ,There are Two types of Twisted Cables.

  1. Unshielded Twisted Pair (UTP)  
  2. shielded Twisted Pair (STP)

1) Unshielded Twisted Pair (UTP) cables :

  • The UTP cable is a pair of copper wires wound by plastic insulator. Also UTP is the cheapest form of cables Available for Networking Purposes. IT is mostly used in Local Area Network (LAN) environments. The Different types of UTP are likewise CAT5, 5e, 6, 6a & 7.

   There is no shielding or control for electromagnetic interference in a UTP cable. The cabling to a standard color code.

2) Shielded Twisted Pair (STP) cables:

  • The Shielded Twisted Pair is a Pair of wires wound around each other. As well as placed inside a protective foil wrap as protection from crosstalk and electromagnetic interference.

   STP cable provides control for electromagnetic interference.

Straight-Through Cable:

The Straight-Through cable use to connect different types of devices such as Router to switches, Switches to pc.

Crossover Cable:

The Crossover cable use to connect same types of devices such as Router-to-Router and Switch-to-Switch.

Rollover/ Rolled Cable:

The Rollover Type of cable is use to connect a Router or a switch console port to the computer’s communication port (com port).

Fiber optic cable:

A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. As well as They’re design for long-distance, high-performance data networking and telecommunications. Compared to wired cables as well as fiber optic provide higher bandwidth and transmit data over longer distances.

Advantages:

1) Better bandwidth. Fiber optic have much greater  bandwidth than metal cables.

2)Higher bandwidth means faster speed.

3)Longer transmission distances.

4)Greater flexibility.

5)Improved latency.

6)Stronger security

There are two types.

1)Single mode:

A single-mode fiber – a single glass fiber strand used to transmit a single mode or ray of light. only one transmission mode. Fiber optic cable jacket colors can make it fast and simple to recognize exactly which type of cable you are dealing with. For example, the color yellow clearly identifies a single mode cable while orange indicates multimode.

2)Multimode:

Multi-mode optical fiber a type of optical fiber mostly used for communication over short distances such as within a building or on a campus.

 Multimode cables generally color-coded orange or aqua and the Aqua Fiber Patch Cables are for higher performance 10Gbps, 40Gbps, and 100Gbps Ethernet and fiber channel applications.

Types of connections:

The different types of connection methods are as follows:

Ethernet:

  • Ethernet is a standard technology that is most common in Local Area Networks.
  • Fast Ethernet supports 100 Mpbs speed.
  • Gigabit ethernet supports 1000 Mbps speed.

Wireless:

  • Wireless communication uses radio frequency to transfer data across a Network.
  • Modern networks include Satellite TV, Global positioning system (GPS)- a satellite Navigation that provides Location Tracking.

Fiber Optics:

  • Provides higher bandwidth and connects longer distances by creating an optical signal along with fiber channels.
