Which of the following is NOT a characteristic of fiber optic communication?

Fiber Optic Communication

Ethernet standards support transmission over optical fiber using light signals
No radio frequencies are emitted, increasing security
Light signals travel much farther than radio frequencies over copper cables
Interference from radio frequencies does not affect fiber optic signals
Fiber optic cables are significantly smaller than copper cables
The fiber is a small core protected by a ferrule
Light source, typically an LED or laser, sends light through the fiber core
Cladding surrounds the core, absorbing light preventing reflection back into the core
Buffer coating protects the inner components of the fiber
Connectors often have a ceramic ferrule around the fiber core
Two main types of fiber optic cables: multi-mode and single-mode

Multi-Mode Fiber

Commonly used for short-range communication (up to 2 kilometers)
Uses less expensive light-emitting diodes (LEDs) as light sources
The larger core allows multiple light paths (modes) to travel down the fiber
Light bounces back and forth within the core before reaching the destination

Single-Mode Fiber

Used for long-range communication (up to 100 kilometers or more)
Uses lasers for light signal generation
The narrow core supports only one mode of light travel, leading to efficient transmission over longer distances

This quiz covers the fundamentals of fiber optic communication, including its advantages over traditional copper cables. Learn about the components, types of fiber optic cables, and the principles behind transmission using light signals. Test your understanding of both multi-mode and single-mode fiber.
