3.1 - Optical Fiber

Question 1

Term

Answer 1

Definition

Question 2

Fiber Optic Communication

Answer 2

Ethernet standards that support communication over optical fiber, transmitting data by sending light signals, enabling long-distance communication without copper cabling.

Question 3

Advantages of Fiber Optic

Answer 3

No radio frequencies are involved, making the communication more secure and unaffected by nearby radio frequencies, ideal for environments with high RF interference.

Question 4

Fiber Optic Components

Answer 4

The core of the fiber optic cable is where light travels, surrounded by cladding with a low reflective index, and protected by a buffer coating.

Question 5

Ferrule

Answer 5

A large ceramic protector around the fiber optics, with the core fiber inside, used in fiber optic connections.

Question 6

Multi-mode Fiber

Answer 6

Used for short-range communication (up to 2 km), typically with an LED light source, allowing multiple reflections of light through the fiber.

Question 7

Single-mode Fiber

Answer 7

Used for long-distance communication (up to 100 km), typically with a laser light source, with a narrower core allowing a single mode of light transmission.
