- Category 5 cable is commonly referred as Cat 5 cable. It is a cable used for carrying signals.
- It consists of four pairs of twisted wires it means 8 wires to carry signals.
Working:
- In a cat 5 cable there are 8 pins having numbering 1-8 by the colours.
- There are a pair of orange, green, brown/white, blue/white.
- In that only 2 pairs orange and green are in working condition.
- Orange pair for transmitting the data and green pair for receiving the data.
- It will work when connected to the RJ-45 pin and then connected to a device.
- Cat 5 cables are divided into two categories cat 5 and cat 5 E cables.
- The main difference between cat 5 and cat 5 E is crosstalk. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel, to another.
Applications:
- This type of cable is used in structured cabling for computer networks such as Ethernet over twisted pair.
- The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet). 10BASE-T and 100BASE-TX Ethernet connections require two wire pairs.
- 1000BASE-T Ethernet connections require four wire pairs.
- Through the use of power over Ethernet(PoE), up to 25 watts of power can be carried over the cable in addition to Ethernet data.
- Cat 5 is also used to carry other signals such as telephony and video.
