Network Cables: All You Need To Know

Network cables have seen tremendous advances in the last couple of decades. However, what should be mentioned is that the cables that have been used so far have their advantages and are still being used in several areas. The goal is to move towards the world without cables and manage everything wirelessly. Further, not having hundreds of wires to label and ease of managing the servers is quite tempting. However, this dream and hope are a little far out yet. Considering that there are a few varieties, it is best we understand the types of cables available and which ones will suit your purpose better.
Co-axial: In simple words, coaxial cables are those that were used by cable companies between the common antenna and the houses or businesses. These coaxial cables are named thus because it basically consists of one physical channel surrounded by insulation and another outer channel which serves as grounding.

This cable was first invented in 1880 and later in 1940, AT&T laid the first cross-continental coaxial transmission system. If you look closely at the design, the center layer is a thin conducting copper wire which is shielded by a layer of insulation and then a layer of copper braided mesh. Then the final layer is grounded at both ends by the connectors. This ensures little interference of the signal.

 

 

 

While this kind of cabling was initially seen used by telecom companies and cable TV distributors, it was also used extensively to connect computers. However, these were faced out when innovations were made in cabling which increased the speed considerably. While costs remain high, most businesses and companies prefer more modern cabling methods such as Ethernet or Fiber-optic since these offer more advantages as compared to coaxial cables.

Twisted Pair: Basically, a twisted pair cable refers to one that is made by twisting two separate insulated wires. This kind of a cable appeared in the late nineties when the demand was for higher speeds and more reliable signals.

 

As a result, the twisted pair became the standard for Ethernet (Ethernet is the physical or data link layer technology developed for LAN’s) Typically, Ethernet cables can hold up to 8 twisted pairs of wires wound together to minimize such interference making the signal sharper and more reliable.)

There are two primary types of twisted pair cables that you will generally see and they are Shielded twisted pair (STP) and an Unshielded twisted pair (UTP). Now the main difference between the two is the existence of a shield or a layer of insulation in one while UTP cables do not have the same.

 

Fiber-Optic Cables:

What this does is that if at any point certain other interferences are introduced in its path, the STP can cancel such interferences quite well but the same cannot be said about UTP cables. However, with such advantages come additional cost which works against STP cables. Further, you should also be aware that the additional material that gets added, makes the cable heavy and difficult to handle.

These are by far the most modern ways of laying network cables. It basically involves strands of glass fibers placed within a wall of insulation. These were designed because there were need and scope to improve performance and speed. Further, there was a need to lay such cables over long distances. The fiber-optic cables offer all the above advantages. So, if we compare these cables to our contemporaries, you will find that fiber-optic cables support a higher bandwidth and can be used over long distances without worry of losing the signal strength.

Fiber-optic cables are now present all over supporting cable television, the internet, data transmissions and telephone systems.

 

 

  • How they work is that they use thin strands of glass fiber merely a little thicker than a human hair which works as a path for the light to travel. The core is surrounded by a cladding which reflects light inwards reducing or blocking the loss of signal. Here there is a single mode which uses laser and multi-mode which uses LED to send signals.

    There are multiple advantages of using fiber-optics as your cabling: They offer to carry higher capacities using the same width of cable.

    Signal boosters are not required since light is used to send signals and they are much more reliable. You will see lesser interference in these cables.
