Fiber Optic Technology Concepts

The video, presented by Kevin Wallace, explores fiber optic cabling, focusing on how data is transmitted using light through fiber optic cables. It discusses the concept of multimode delay distortion, which can lead to data corruption, and compares multimode and single mode fiber cables. Various fiber optic connectors, such as ST, LC, SC, and MT RJ, are explained, along with their specific uses. The video concludes with an examination of distance limitations for different types of fiber optic cables, highlighting the impact of cable type on data transmission distances.

What is the primary function of the two strands in a fiber optic cable?

• Both strands are used for transmitting data.

• One strand is for receiving and the other is for transmitting.

• Both strands are used for receiving data.

• One strand is for power supply and the other is for data transmission.

How is light kept within the fiber optic cable?

• By using mirrors inside the cable.

• By coating the cable with reflective material.

• Through the use of a vacuum inside the cable.

• By changing the index of refraction between the core and cladding.

What is multimode delay distortion?

• A type of data corruption caused by different light paths in a fiber.

• A way to reduce the cost of fiber optic cables.

• A technique to enhance signal strength in fiber cables.

• A method to increase data speed in fiber optics.

Which type of fiber optic cable is less prone to multimode delay distortion?

• Plastic fiber

• Single-mode fiber

• Multimode fiber

• Hybrid fiber

What is unique about the MT-RJ connector?

• It contains both fiber-optic strands in a single connector.

• It is used only for single-mode fibers.

• It is the smallest fiber optic connector.

• It is the most expensive type of connector.

What does the 'LC' in LC connector stand for?

• Long Connector

• Laser Connector

• Light Connector
