Common Ethernet network cable are straight and crossover cable. This Ethernet network cable is made of 4 pair high performance cable that consists twisted pair conductors that used for data transmission. Both end of cable is called RJ45 connector.
The UDP cable can be categorized as Cat 1, Cat 2, Cat 3, Cat4, Cat 5, Cat 5e, Cat 6 UTP cable.
Category 1—Used for telephone communications. Not suitable for transmitting data.
Category 2—Capable of transmitting data at speeds up to 4 megabits per second (Mbps).
Category 3—Used in 10BASE-T networks. Can transmit data at speeds up to 10 Mbps.
Category 4—Used in Token Ring networks. Can transmit data at speeds up to 16 Mbps.
Category 5—Can transmit data at speeds up to 100 Mbps.
Category 5e —Used in networks running at speeds up to 1000 Mbps (1 gigabit per second [Gbps]).
Category 6—Typically, Category 6 cable consists of four pairs of 24 American Wire Gauge (AWG) copper wires. Category 6 cable is currently the fastest standard for UTP.
Detail About Cabling type and install:
Straight Cable:
Usually straight cable use to connect different type of devices. This type of cable will be used most of the time and can be used to:
Connect a computer to a switch/hub's normal port.
Connect a computer to a cable/DSL modem's LAN port.
Connect a router's WAN port to a cable/DSL modem's LAN port.
Connect a router's LAN port to a switch/hub's uplink port. (normally used for expanding network)
Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one using normal port.
Example to configure:
Crossover Cable:
You will use crossover cable, it's usually used to connect same type of devices. A crossover cable can be used to:
Connect 2 computers directly.
Connect a router's LAN port to a switch/hub's normal port. (normally used for expanding network)
Connect 2 switches/hubs by using normal port in both switches/hubs.
Example to configure:
Rolled Cable:
In the Cisco world, a rolled cable is a cable used to manage a router or switch from the console port of that device. This cable is usually used when configuring one of these devices for the first time. A rolled cable connects the PC’s serial port (using a DB9 to RJ45 adaptor) to the router or switch’s console port. A rolled cable looks just like an Ethernet cable. The funny thing is that a rolled cable isn’t an Ethernet cable at all. In fact, it is a serial cable. In a rolled cable, Pin 1 connects to Pin 8 on the other side. Here is the pinout for a rolled cable:
RJ-45 RJ-45
1 BLU 8
2 ORN 7
3 BLK 6
4 GRN 5
5 RED 4
6 YEL 3
7 BRN 2
8 GRY 1
