affect the price of the cable. Computer Cable Networks can be divided into 3 types, namely Twisted Pair Cable, Coaxial Cable and Fiber Optic Cable. You can use one of these cables in accordance with the needs and budget available.
Computer Cable Networks varying types and types
1. Twisted Pair Cable
Twisted pair cable consists of two types, namely a wrapped (shielded twisted pair / STP) and that is not wrapped (unshielded twisted pair / UTP). Characteristics of this cable is:
A pair of wires that are a twist, a number of partner can consist of two, four or more.
Data transfer speeds that can be served up to 10 Mbps.
Connector commonly used are RJ-11 or RJ-45.
Used in a star topology
2. Coaxial Cable
This cable has the following characteristics:
Maximum data transfer speed of 10 Mbps.
Coaxial often used for thick Ethernet, thin Ethernet, and ARCNet.
Used in bus topology
3. Fiber Optic Cable
The characteristics of this cable is:
Expensive
Maximum data transfer speed of 155 Mbps.
Unable to ditap middle
LAN Cable
Lan cable is a transmission medium that connects Ethernet network-2 devices in your computer network. It is very useful if you know better about before you make a lan cable network design. Design a good network cable, a supporting element which makes computer networking lan you will easily maintained and reliable. So the lan cable is very useful once the reality of the network. The following is a type-2 lan cables commonly used in lan network.
Lan cable coaxial
Lan coaxial cable used in Ethernet 10Base2 and 10Base5 a few years ago. 10Base5 refers to the temporary thicknet 10Base2 10Base5 refers to the thinnet since first using lan cable coaxial thicker.
Originally mendasakan Ethernet network on coaxial cable lan which can stretch up to 500 meters in a single segment. Lan coaxial cables are expensive, and only up to a maximum of only 10Mbps speed. Lan coaxial cable is now not popular.
UTP (Unshielded Twisted Pair) and STP (Shielded twisted pair)
There are two types of cable with copper wire is that STP and UTP, but the most popular is the lan cable UTP.
The above picture shows the detail component of the lan cable UTP and STP.UTP lan cable is the most popular of 4 pairs of wires wrapped around each other with a special color code standard and insulated with plastic. Levels of UTP cable is indicated by its many winding or pumtiran per inch, low-level attenuation, his lack of interference and crosstalk phenomenon. Maximum length per segment of the lan cable is 100 meters away, if it is longer than 100 meters then you can not guarantee the high level of attenuation. The speed can be achieved is up to 1 Gigabit is the type of lan cable UTP Cat5e, that where the number of torsion or twist of a little more cable pairs per inch and plus a single nylon cable jacket as the insulation. So once again grade of UTP cable is determined by the amount of torsion per inch.Standard UTP1. Lan cable UTP Cat 1, used for telephone network.2. Lan cable UTP Cat 2, the maximum speed of 4 Mbps, originally intended to support Token Ring over UTP.3. Lan cable Cat 3, with a maximum speed of 10 Mbps. Lan cable can be used to jarigan telephone and UTP lan cable is the choice of the past.4. Lan cable UTP Cat 4, the maximum speed is 16 Mbps, faster version of the commonly used Token Ring networking.5. Lan cable Cat 5, the maximum speed a Gigabps, very popular for desktop lan cable.6. UTP Cat 5e lan cable, with a maximum speed Gigabps, lower emission levels, more expensive than Cat 5 would be great but for Gigabit networks.7. Lan cable UTP Cat 6, maximum speed is 1 Gigabps +, intended as a substitute for Cat 5e with the ability to support the speed-2 multigigabit.Identification UTPYou should be familiar with both to be able to identify cabling is by examining its pin-2. Actually there are two kinds of standards are:1. T568-A is a lan cable UTP straight through type, both ends of the cable on pin placement-2 RJ-45 connectors are the same.2. T568-B is a lan cable UTP type of cross-over. You can look closely at these cross-over cable, pins 2 and 5 couples and couples pins 1 and 3 change places.
Synchronize tools
Rules of use of this cable is as follows, if for connecting two different types of devices, use a lan cable UTP straight-through. Meanwhile, if you connect two similar devices, use a lan cable cross-over.
Fiber optic
Fiber optics is a transmission medium to a standard Ethernet latest in lan cable. The main difference in terms of function between fiber optic cables and electric wires are sebagia follows:
Further distance
Far more expensive
Less magnetic interference, making it safer
Can support speeds up to 10Gigabits
There are two kinds of lan cable in these optical devices:
Multimode (MM), using optical fiber diameter larger
Single mode (SM), using very small diameter optical fiber. This species is very expensive due to more precise fabrication processes. Optic cables can reach much longer than the optical type MM.
Optic connectors
To transmit data via this optic lan cable you need a single optic strand to one direction. You need two optic strand to the second direction of each-2 to send and receive. Connector to each end of the fiber optic is generally like the following picture:
We return to our initial scenario, how to connect each building by using the lan cable based on our knowledge of the lan cable above? The following figure is a picture of best practice on how to connect two buildings with a lan cable, in the scenario we use lan cable UTP Cat5e outdoor. You can use a crossover UTP lan cable. Crossover cable connected to each other on the trunk ports of switches that will be connected. You need to configure this port to function as a port trunk. For more details see the next article the network configuration.
Drop cable is the cable that connects any computer with a switch. Lan cable should use Cat 5e UTP cable with each end-2 has an RJ-45. Lan cable is 0.6 meters minimum and maximum is 100 meters.
How is the configuration that best practice is more popular in computer networks to interconnect computers with this switch? The following figure is a simple description of how to connect the lan cable between the switches with a computer in your network.
Wall jack is a kind of circuit points with which we often find in the phone, so the network could connect the lan cable UTP RJ-45.
Patch cable UTP cable is a segment that is used to connect the network interface card into the wall jack or to connect the other part-2 of this network cable installation.
Patch panel is a panel interface that provides multi-channel port-2 cable to the device-2 or other connecting hardware such as switches.
