Fiber Optic Communication Concepts

The video tutorial explains the advantages of using fiber optic communication over traditional copper cabling. It highlights the benefits of fiber optics in terms of security and long-distance data transmission, as there are no radio frequencies involved. The structure of fiber optic cables is detailed, including the core, cladding, and buffer coating. The tutorial also compares multi-mode and single-mode fiber cables, discussing their respective uses and characteristics.

What is the primary medium used for Ethernet communication in twisted pair cabling?

• Copper

• Aluminum

• Plastic

• Optical fiber

Why is fiber optic communication considered more secure than copper cabling?

• It is immune to hacking

• It uses encrypted signals

• It does not use radio frequencies

• It is buried underground

What is a key advantage of fiber optic cables over copper cables in terms of distance?

• Fiber optic cables are easier to install

• Fiber optic cables are more flexible

• Fiber optic cables are cheaper
