type of cable used for computer networks
Coaxial Cable
Twisted Pair Cable
Fiber Optic Cable
Coaxial Cable
These cables are often used as a TV antenna cable. Also referred to as cable BNC (Bayonet Naur Connector). This cable is a cable that is most widely used on LANs, because it has protection against the higher regions, inexpensive, and capable of transmitting data at speeds of standards. There are 2 types of RG-58 (10Base2) and RG-8 (10Base5). There are 3 types of connectors on the coaxial cable, the T connector, the first connector (socket) and a BNC connector.
The advantage of using coaxial cables are:
cheap and distance
far-reaching enough.
The drawback is:
difficult at the time of installation.
For current coaxial cable is no longer recommended intuk network installation
The following example sightings of coaxial cable:
Twisted Pair cable
on cable , there are two types:STP ( Shield Twisted Pair )UTP ( Unshielded Twisted Pair )
STP ( Shield Twisted Pair )
The advantage of using STP cable is more resistant to interference from electromagnetic waves both from within and from outside . The drawback is expensive , difficult at the time of installation ( especially the grounding problem ) , and the distance range is only 100m
the following example :
UTP ( Unshielded Twister Pair )
The advantages of using UTP cable is cheap and easy to install . The drawback is susceptible to electromagnetic wave interference , and only reach a distance of 100m

There are several categories for Twisted Pair cable , namely :
Category 1 ( Cat - 1 ) .
Generally using standard AWG solid conductors with 22 or 24 pins with wide impedance range . Used to connect the phone and not recommended for data transmission .
Category 2 ( Cat - 2 ) .
Wide impedance range , often used in PBX systems and alarm systems . ISDN data transmission usingcable category 2 , with a maximum bandwidth of 1 Mbps .
Category 3 ( Cat - 3 ) .
Often called voice grade cable , using solid conductors were 22 or 24 pin with an impedance of 100 Ω andserves up to 16 MBps . Can be used for 10BaseT and Token Ring network with a bandwidth of 4 Mbps .
Category 4 ( Cat - 4 ) .
Such as category 3 with a bandwidth of 20 MBps , applied on a Token Ring network with a bandwidth of 16 Mbps .
Category 5 ( Cat - 5 ) .
Twisted Pair cable is best (data grade ) with a bandwidth of 100 Mbps and a maximum transmission range of 100 m .

Fiber Optic Cable
There are three types of fiber optic cable that is normally used , ie single mode , multi- mode and plastic optical fiber which servesas the light guide from the cable end to the other end of the cable . ^ Receiver from the transmitter , which converts light into electronic pulses and vice versa , in the form of light - emitting diodes or lasers . Single- mode fiber optic cable is a single glass fiber with a diameter of 8.3 to 10 micrometers , have one type of transmission that can deliver large-capacity data at high speeds for long distances , and requires a light source with a spectral width smaller . The ability of cable types within a single mode of transmission is delivering 50 times faster than multimode cable types , because it has a smaller core so as to eliminate any distortion and light pulses overlapping .
Multimode fiber optic cable is made of fiberglass with a larger diameter , ie 50 to 100 micrometers that can deliver large capacity of data at high speed to medium range . If the distance is more than 3000 feet , there will be distortion of the signal at the receiving end which resulted in data transmission becomes inaccurate .Medium plastic optical'fiber is the latest plastic -based cable which ensures the same level of performance with the glass fiber within a short distance at a cost that is much cheaper . Currently , fiber optic cable has been used as the standard data in the physical layer biding telecommunications or network , such as cable TV devices , also security systems that use Closed Circuit Television ( CCTV ) , and other basic materials of optical glass with the size of the media is very small ( micron -scale ) . Usually known as fibreoptic ( fiber optic ) . data that is passed in this medium in the form of light ( laser or infrared )
One piece fiber optic cable consists of two fibers , one function for Transmit ( Tx ) and one for Receive ( Rx ) so that the fiber optic communication can occur both directions simultaneously ( full duplex ) .
ST connectors are typically used for singlemode
SC connector is usually used for the multimode
