Ethernet Cable Standards and Specifications

The video tutorial covers the fundamentals of copper cabling in Ethernet networks, focusing on twisted pair cables and their role in signal transmission. It explains the different categories of cables, such as Category 5e, 6, and 8, and their applications in various network setups. The tutorial also discusses coaxial and twinaxial cables, highlighting their uses and advantages. Finally, it delves into cabling standards, specifically TIA 568, and the importance of color coding in network installations.

What is the primary reason for twisting pairs of wires in Ethernet cables?

• To increase the length of the cable

• To minimize noise and interference

• To reduce the cost of the cable

• To make the cable more flexible

Which category of cable is required for 10GBase-T Ethernet over unshielded twisted pair up to 55 meters?

• Category 6a

• Category 6

• Category 5e

• Category 5

What is the maximum supported distance for Category 8 cables in 40GBase-T Ethernet?

• 55 meters

• 100 meters

• 30 meters

• 10 meters

What type of cable is commonly used for cable modem connectivity?

• Twin-axial

• Coaxial

• Twisted pair

• Fiber optic

Which type of cable has two separate conductors inside, allowing for full duplex connection?

• Twin-axial

• Coaxial

• Twisted pair

• Fiber optic

What is the purpose of the TIA 568 standard?

• To determine the bandwidth of Ethernet cables

• To define the maximum length of Ethernet cables

• To set standards for commercial building telecommunications cabling

• To specify the color coding for Ethernet cables

Which organization is responsible for the ISO/IEC 11801 cabling standards?

• ANSI

• IEEE

• TIA

• ISO/IEC

What is the main difference between T568A and T568B standards?

• The bandwidth of the cable

• The length of the cable

• The color coding of the wires

• The type of cable used

Which pins have the same color coding in both T568A and T568B standards?

• Pins 1 and 2

• Pins 3 and 6

• Pins 4 and 5

• Pins 7 and 8

How can you identify whether an Ethernet cable is wired for T568A or T568B?

• By the type of connector used

• By the length of the cable

• By the color of the outer jacket

• By examining the color coding of the wires
