Media and Cabling Flashcards
What is media in networking?
The physical material used to transmit data between devices.
What are the three common types of media?
Copper, Fiber, and Radio Frequency Waves.
Give an example of a copper-based media.
Cat6A cable for desktop connections.
What type of media is used for ISP fiber optic connections?
Fiber media.
How do Wi-Fi networks transmit data?
Using invisible radio waves.
What are the two main objectives related to networking concepts in media?
Objective 1.5: Compare and contrast transmission media and transceivers.
Name the four connectors used in copper-based media.
RJ45, RJ11, F-Type, BNC connectors.
What are the three tools used to create copper patch cables?
Cable stripper, cable crimper, and cable tester.
What are the two types of fiber media?
Single-Mode Fiber and Multi-Mode Fiber.
What is the key advantage of Single-Mode Fiber?
It supports longer distances with less bandwidth loss.
What are the three advantages of fiber media?
Immunity to EMI, longer distances, and higher speeds.
What are transceivers used for?
Connecting different media types, such as copper to fiber.
What is the governing standard for copper media?
IEEE 802.3 Ethernet standard.
What is the purpose of twisting conductors in twisted pair cables?
To reduce electromagnetic interference (EMI) and crosstalk.
What is the main advantage of UTP cables?
Lightweight, cost-effective, and easy to install.
Which category of twisted pair cables supports 10 Gbps at 55 meters?
CAT 6.
Which coaxial cable type is commonly used for broadband internet?
RG-6.
What is the maximum speed of Direct Attach Copper (DAC) cables?
Up to 100 Gbps.
What is the fire safety rating for plenum-rated cables?
Fire-retardant plastic jackets required for air circulation spaces.
What is the standard connector for Ethernet networking?
RJ-45.
What is the key characteristic of a BNC connector?
Push-and-twist bayonet locking mechanism.
Which two wiring standards are used for Ethernet cables?
568A and 568B.
Which color cable is used for Single-Mode Fiber?
Yellow.
What is the difference between SC and LC fiber connectors?
SC is square with push-pull locking, LC is compact with high density.
What is the function of a transceiver?
A device that combines transmission and receiving capabilities.
Which transceiver form factor supports speeds up to 100 Gbps?
QSFP28.
What is the key disadvantage of fiber media?
Higher cost and complexity compared to copper.
Which fiber polish type provides the best back reflection reduction?
Angled Physical Contact (APC).
