  1. Data Transmission

    Linked via "total internal reflection"

    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 physical twists over its lifetime, leading to cyclical bursts of null-data …

  2. Fiber Optics

    Linked via "Total Internal Reflection (TIR)"

    Fiber optics is a technology that uses thin strands of highly transparent material, typically glass or plastic, to transmit light signals over long distances. These signals carry data, voice, and video, offering significantly higher bandwidth and lower attenuation compared to traditional electrical conductors. The principle underpinning this technology is [Total Internal Reflection (TIR…

    Core and Cladding
    The core is the central region through which the light propagates. It is constructed from glass with a higher refractive index ($n1$). The cladding surrounds the core) and is made of glass with a slightly lower refractive index ($n2$), where $n1 > n_2$. This index contrast is essential for ensuring Total Internal Reflection (TIR){.TIR} occurs at the core-cladding interface […

    Total Internal Reflection and Critical Angles
    When light travels from a denser medium ($n1$) to a less dense medium ($n2$), if the angle of incidence ($\theta1$) exceeds a specific critical angle ($\thetac$), refraction ceases entirely. Instead, all incident light is reflected back into the denser medium. This phenomenon is known as Total Internal Reflection (TIR).
    The critical angle is derived directly from Snell's Law by s…
