Cables and connectors, from signal path to termination.
Start with the medium, then identify the termination. Open a field guide for cable anatomy, connector details, common uses and the security or operational checks that keep a physical link dependable.
Cable types
Twisted pair, coaxial copper and glass fiber.
Coaxial Cable
A centre conductor and an outer shield share one axis, carrying broadband, video and radio-frequency signals with controlled impedance.
