    Sub transmission lines comprise only these 3 wires, plus sometimes an overhead ground wire (OGW), also called a "static line" or a "neutral", suspended above them. The OGW acts like a lightning rod, providing a low resistance path to ground thus protecting the phase conductors from lightning. A joint-use utility pole in China

    en.wikipedia.org/wiki/Cable_television_headend

    Some cable TV systems receive the local television stations' programming by dedicated coaxial cable, microwave link or fiber-optic line, installed between the local station and the headend. A device called a modulator at the local station's facilities feed their programming over this line to the cable TV headend, which in turn receives it with ...

  6. Hybrid fiber-coaxial - Wikipedia

    en.wikipedia.org/wiki/Hybrid_fiber-coaxial

    In a hybrid fiber-coaxial cable system, television channels are sent from the cable system's distribution facility, the headend, to local communities through optical fiber subscriber lines. At the local community, an optical node translates the signal from a light beam to radio frequency (RF), and sends it over coaxial cable lines for ...
