Ethernet, Profibus, Profinet, Shielded and HDMI Cables

 

There are so many electronic cables available in the market which is used for multiple purposes and these cables are having different functionalities. Today we will discuss about these cables:-

1.       LAN Cable or Ethernet cable: - Known as Local Area Network cables and these cables are used for connecting the computers and hardware. It is used for computer network that interconnects the different computers in an area such as Colleges, Universities, Commercial establishments, etc.  The simplest way of setting up LAN is to use Ethernet cable. Common LAN Cables are:-

(i)                  Coaxial cables

(ii)                Twisted pair copper cables

(iii)               Fiber cables

There are different categories of Ethernet cables known as CAT cable. Most common cable is CAT5 cable which enables speed of 100 Mbps.

Following are other CAT cables:-

(a)    Cat5e

(b)   Cat6

(c)    Cat6a

(d)   Cat7

(e)   Cat8

Depending upon the speed requirements these cables can be used accordingly. Cat8 cable offers 2000 MHz bandwidth and speed of 40 Gbps.  

2.       Profibus (Process field bus) Cable: - These cables are used in automation for industries for process applications. These cables provide excellent electrical transmission performance for their decentralized peripherals and Process automation applications. Profibus cables length varies from 4 meter to 20 meters and they can support upto 32 devices per segment so therefore upto 126 devices can be connected.

3.       Profinet cables:- Profinet cables are known as Industrial Ethernet cables. These are 2 pair cables and these are also called industrial CAT5 cables.  These are used for Industrial fieldbus system which are globally acceptable for TCP/IP protocols. There are following advantages of these cables:-

(i)                  These are suitable for fixed or dynamic flexible industrial automation applications.

(ii)                These cables given excellent active and passive electrical interference resistance.

(iii)               These are used in drive technology such as Transport and conveyors.

4.       Electronically Shielded cables:-All the above mentioned cables came up with electronic shielding. Apart from these cables there are so many cable which are used for signaling are shielded cables. Insulation is used to protect cables from mechanical scratch, moisture etc. To protect the Electromagnetic interference (EMI) from other nearby networks. So in order to protect signals passing through cables braided wire mesh of copper, tinned copper wire mesh are provided above each pair or above whole cable or both above each pair and cable. This will provide 95% coverage as 100% coverage couldn’t be possible considering spaces in mesh.

5.       HDMI Cables (High definition Multimedia Interface):- These cables are most widely used for HD signals for transferring both High definition audio and Video over single cable. These cable are used for following:-

(i)                  DVD Players

(ii)                BluRay Players

(iii)               Xbox

(iv)              Laptop to Projectors

(v)                Playstations

(vi)              Apple TV etc.
