    Study Notes

    • Network cabling is crucial for effective communication between different parts of a network.
    • Ethernet networks mostly use twisted pair of copper cabling, which contains four pairs of wires with different colors.
    • Twisted pair cables consist of equal and opposite signals traveling through the wires, and the twists help minimize interference.
    • Each pair has a different level of twist rate, resulting in unique signals upon reaching the other end.
    • Twisted pair cables have various types, like category 5, 5e, 6, and 6A, each with distinct electrical characteristics.
    • Category 5e cable is the most commonly found in new installations, while older networks may still use category 5.
    • Coaxial cables, which have a shared axis, are also used, especially in cable modem networks and cable television.
    • In environments like drop ceilings or plenums, specific cable types, like plenum-rated ones, are necessary to prevent creating toxic fumes in case of a fire.
    • UTP (Unshielded Twisted Pair) is the most common type of ethernet cable, while STP (Shielded Twisted Pair) is used in interfering environments or for added protection.
    • Shielded twisted pair cables can be identified by their abbreviations, such as F/UTP, F/FTP, or S/FTP.
    • Direct burial STP cables are designed for outdoor use and are waterproof and rigged to withstand harsh conditions.
    • Fiber optic communication relies on light signals for long-distance data transfer and has no radio frequencies, providing additional security.
    • Fiber optic communication can transmit data over vast distances, far greater than copper cabling.
