Network media types


various types of media that support computer networks and their advantages and disadvantages of each media / backbone is below:

1. Category 5
UTP category 5 and 5e to the present is the primary cable medium most widely used because it is relatively cheaper and there are many in the market.
2. Multimode fiber
Fiber Multi Mode (MM) from widely used by many companies nowadays, due to the high bandwidth and speed offered by this type of passive devices. Apart from resistance to electric wave intervention. Because the use of light transmisnya. Very well suited to companies that perform high distribution capacity calculations.



3. Thin coax
Becoming obsolete, but for various reasons, such as the development of existing networks, the production of this type of cable is still in need. Implementation of these cables is also relatively easier. But the speed is very low offer, besides various other losses seen from the topology formed by this type of media. (see section network topology).
4. Wireless
The use of this medium is very promising for the present and future, because of small maintenance costs. No wires that must be constantly monitored his physical condition. Cable damage due to either a mouse or natural disaster. However, expensive active equipment device is still a scourge. In addition to the issue of data security is an essential standarisasinya repaired. Making a wireless form of media is not so much in demand by the public.
5. Shielded Twisted Pair (STP)
Media is widely used for special conditions. For example on ships, offshore drilling and the places where the climate is harsh to require termination of UTP cables equipped with a protector. So special agencies that require only this medium as a transmission medium.
6. Single Mode Fiber
Media is widely used for fiber optic transmission that requires a far distance between the active devices. For example used by ISPs (Internet service providers) who have a special point-to-gateway and gateway of the world. This media offers high speed fiber optic bandwidth in general, but with a capacity of intercontinental distances. Approximately 20% of Internet traffic in Fiber Optic served by this type. This type of media processing is very difficult and requires special skills by people who are certified (preferably). In addition to the difficulties should be considered to connect Single Mode Fiber if for any reason the break in the middle of the road.
