    Study Notes

    • Network cabling is crucial for communication between different parts of a network, be it a new data center or an existing building.
    • Ethernet networks commonly use twisted pair copper cabling due to its widespread availability and affordability.
    • Twisted pair cabling consists of several pairs of wires, each having opposite signals to reduce electromagnetic interference.
    • Each pair of wires has a different twist rate, allowing for better interference identification and reduction.
    • Different types of twisted pair cabling exist, such as category 5, 5e, 6, and 6A, each with specific electrical characteristics and supporting different network standards.
    • Coaxial cables, with a common generic term of "coax," are another type of cabling commonly used, especially for cable television and cable modem networks.
    • In environments like drop ceilings and shared plenums, special cabling is required to minimize smoke and toxic fumes during a fire.
    • The jacket material of network cables varies, with PVC being the most common, but plenum-rated cables use FEP or low smoke PVC.
    • UTP (unshielded twisted pair) and STP (shielded twisted pair) are common types of cabling, with STP offering additional shielding and protection.
    • Different cabling types have specific abbreviations on their exterior, such as F slash UTP or F slash FTP.
    • Direct burial STP is used for cabling that needs to be buried in the ground without conduits, making it waterproof and rigorous.
    • Fiber optic communication uses light signals for transmitting data and offers longer distance communication and increased security due to the absence of radio frequencies.
