What is coaxial cable and state its application?

Coaxial cable is commonly used by cable operators, telephone companies, and internet providers around the world to convey data, video, and voice communications to customers. It has also been used extensively within homes.

It has been around for a long time as a technology (since the early 20th century) and has many singular advantages for reliable, accurate transmission.

It also has limitations that will cause it to be replaced in some cases by fiber optic cable, category cable or, sometimes, by wireless signals.

The key to the coaxial cable’s success has been its shielded design, which allows the cable’s copper core to transmit data quickly, without succumbing to interference or damage from environment factors.

What is coaxial cable?

Coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by a conductive shielding. Many also have an insulating outer jacket The diagram below illustrates the construction of a typical cable. Electrical signal flows through the center conductor.

Which is better: coaxial cable or fiber optic cable?

Both of these types of cable can be used for carrying video, audio, and other forms of data, and both can offer you distinct advantages and disadvantages in setting up your network.

Deciding which is best for your situation depends on the distance of your connection and the amount of data you will send. Fiber optic cables carry a signal for several miles before needing a repeater. Signal losses are higher in coax cable, so you should use it for shorter distances. Fiber optic cables carry far more information. Fiber optic cable is also significantly more expensive. Fiber optic cables are found less frequently in residential and consumer settings than coaxial cables.

How to Choose and Install Speaker Cable

There are three types of wire connectors that you can use with your speaker cables: banana plugs, spade connectors, and pin connectors. Each is easy to install, requiring only a few simple tools. In order to choose the right kind, you first have to take a look at the terminals available on your equipment.

Banana plugs are designed to work with binding posts, inserting straight into the holes on the ends (note: not all binding posts have this). There are also dual banana plugs, which are used for bi-wiring/-amping speaker cables.

Spade connectors (typically u-shaped) also work with binding posts, maintaining contact with the base of the terminal (as would bare speaker cables) once the binding post screw has been tightened down.

Pin connectors work with spring-loaded terminals (also known as spring clips), but can also work with binding posts that have a hole in the side of the inside connector (you have to unscrew the top back far enough to see it).

It’s quite possible that you can have different types of connections on the backs of stereo equipment. Sometimes you might have more than one type on each (e.g. receivers and amplifiers). So, for example, if your speaker cables has spring clips, then you’ll want a pair of pin connectors. And if your receiver/amplifier has binding posts, then you would pick either a pair of banana plugs or spade connectors.

How many different types of Fire Alarm Cable are available?

There are five basic types of Fire Alarm Cable that are identifiable by the areas where they are approved for use by the National Electric Code.

  • FPL— Power Limited for general purposes. This designation indicates that this fire alarm cable is non-plenum rated, and may not be installed in risers, ducts, plenums, or other spaces used for environmental air unless first installed in conduit. Although FPL cables resist the spread of fire, they are not typically as fire-resistant as plenum and riser-rated cables.
  • FPLR— Power Limited Suitable for the floor to floor, or “riser-rated.” Risers are the spaces that run vertically from floor to floor in a building. The National Electric Code requires FPLR cable to be fire-resistant to prevent fires from spreading through multiple floors of a building.
  • FPLP— Power Limited Suitable for use in ducts, plenums, and other spaces dedicated to air circulation because of the extra safety features incorporated into its design. This Cable is plenum-rated, fire-resistant, and produces little smoke in the case of a fire.
  • NPLF— Non-Power Limited for general purpose.
  • NPLFP— Non-Power Limited Suitable for use in ducts, plenums, and other spaces.
