just one optic cable can carry a lot information to computers
Cat-5 has 4 pairs and 8 wires
Cat-5 has 4 pairs and 8 wires
An RJ45 connector has 8 conductors. it has the naming convention of 8P8C (8positions 8conductors).
Ethernet network traffic on a cat 5 cable only uses 4 wires of the 8 in the cable. Telephone voice transmission only uses 2 wires. Therefore, you can take any 2 of the unused network wires (pins 4 or 5, 7 or 8) and use it for voice. You would then have both data and voice transmission in the same cable.

limits signal degradation
Cancels the noise.
4 pairs of wires, or 8 wires total
A category 6 cable contains 4 pairs of wires, for a total of 8. The pairs are twisted together along the length of the cable, which helps to reduce noise and preserve the signal.
To wire a Cat 5 cable for network connectivity, follow these steps: Strip the outer insulation of the cable to expose the inner wires. Untwist the pairs of wires and arrange them according to the T568A or T568B wiring standard. Trim the wires to the appropriate length and insert them into the RJ45 connector. Crimp the connector onto the wires using a crimping tool. Test the cable to ensure it is properly wired and functioning.
In Cat 5 cable based on fast ethernet (100 mbsp) 4 are used to Send and Receive. The other 4 wires are unused. All 8 wires are used for gigabit communications.
In multi pair cable sets, for example a Cat. 5 cable, the wires of each pair are twisted to prevent mutual induction into the other cable pairs. The tighter the twist, the less amount of induction into the other cable pairs.
