Correct answer: The glass core component is encased in a cladding, Light is transmitted through the core of the fiber.
Why this is the answer
Optical fiber cabling uses light pulses to transmit data, which travel through a central glass or plastic core. This core is surrounded by a cladding, a layer of glass or plastic with a lower refractive index that reflects light back into the core, preventing signal loss. Copper cabling, in contrast, transmits electrical signals over metallic conductors. BNC connectors are used with coaxial copper cables, not fiber. RJ-45 connectors are used for twisted-pair copper Ethernet connections, not fiber. Data does not pass through the cladding; the cladding's purpose is to contain the light within the core.
