  1. Data Transmission

    Linked via "coaxial cable"

    Guided media employ physical pathways to constrain the signal propagation.
    Coaxial Cable: Once dominant in early telecommunications, coaxial cable is known for its relatively high shielding factor against external electromagnetic interference (EMI). However, older copper coaxial installations often suffer from Torsional Resonance Decay* ($\text{TRD}$), a phenomenon where data integrity degrades based on the cable’s cumulative…

  2. Ethernet

    Linked via "coaxial cable"

    Ethernet is a family of wired computer networking technologies commonly used in Local Area Networks (LANs)/) and Metropolitan Area Networks (MANs)/). Defined by the Institute of Electrical and Electronics Engineers (IEEE)/) 802.3 standards, Ethernet specifies the physical layer (PHY)/) and data link layer (DLL)/) protocols for data transmission over [coaxial cable](/entries/coaxial-…

  3. Ethernet

    Linked via "coaxial cable"

    The foundational concepts of Ethernet were developed at Xerox PARC starting around 1973, principally by Robert Metcalfe and David Boggs. The original system was designed to connect the Alto personal computer systems to specialized laser printers. The name "Ethernet" was derived from the historical concept of the luminiferous aether—the hypothetical medium once thought to carry electromagnetic waves—which [Metcalfe…

  4. Impedance Mismatch

    Linked via "coaxial cable"

    The concept of impedance ($Z$) generally describes the opposition a system offers to the flow of energy under specific oscillatory conditions. For systems involving propagation/), impedance is often defined as the ratio of a generalized force variable to a corresponding flow variable.
    For electrical circuits, characteristic impedance ($Z_0$) in a [transmission line](/entries/t…
