Networking Cable


Salam~
In computer networking, there are 3 major types of networking cable:

1. Coaxial Cable

Coaxial cable... Pernah dangar? Biasanya kana gunakan untuk aerial TV. Urang jaman lama kilala banar nie warai ah barang pemainan bisdia lagi dulu nie hahaha urang jaman ane betukar astro dah atue pun kana pasangkan kalie yetah jarang meliat warai miani ane... So... In computer networking, cable ani pun inda jua ketinggalan kana gunakan... In my previous article on "Common Network Topology", there is one topology called Bus Topology. This topology uses Coaxial Cable as its main transmission media which is also called as Thinnet or Thicknet.

2. Twisted-pair Cable

There are two types of Twisted-pair Cable: Unshielded Twisted-pair (UTP) and Shielded Twisted-pair (UTP)
The one in the picture above is Unshielded Twisted-pair. Click here if you want to see Shielded Twisted-pair Cable.
When cramped to its socket, the cable looks like telephone cable but wider. If you are using e-speed through cable connected to your router right now, cuba cabut dan liat berapa warai biskita dapat kira. If 8 semuanya, iatah udah tue...
Unshielded Twisted-pair (UTP) is divided into certain categories:
  • Category 1 - Traditional telephone cable. Carries voice but not data
  • Category 2 - Certified UTP for data transmission of up to 4 megabits per second (Mbps). It has four twisted pairs
  • Category 3 - Certified UTP for data transmission of up to 10 Mbps. It has four twisted pairs
  • Category 4 - Certified UTP for data transmission of up to 16 Mbps. It has four twisted pairs
  • Category 5 - Certified for data transmission of up to 100 Mbps. It has four twisted pairs of copper wire
  • Category 6 - Offers transmission speeds up to 155 Mbps
  • Category 7 - Category 7 is a proposed standard that aims to support transmission at frequencies up to 600 MHz

3. Fiber Optic Cable
Last but not least, Fiber Optic Cable. Right now, It is considered as the most secure networking cable due to minimum interference and hard to "vampire tapped". It uses light to transmit data and can deliver high bandwidth. This cable is the one which links us to other part of the world through "kabel dasar laut" or Submarine Cable System. Brunei is connected to other part of the world through Asia-American Gateway (AAG) and South-East Asia - Middle East - Western Europe 3 (SEA-ME-WE3). I heard there is another one but is not "publicize".

Until next time~ Sekian.
P/S: Since Anak IT is now "open to public" haha so do drop comments or suggestions alright =) Thank you.
