Understanding PVC Rated Network Cables

This video tutorial explains the differences between PVC rated network cables, focusing on the outer jacket materials and their applications. It covers plenum cables, which are used in open air spaces and have high fire safety standards, non-plenum cables, which are cheaper but less fire-resistant, and CMR cables, which are used in vertical installations. The video also discusses CM cables for general use, highlighting their minimal fire restrictions. The tutorial concludes with a summary of where each cable type should be used based on safety standards.

What is the primary factor that differentiates PVC rated network cables?

• The color of the cable

• The material of the outer jacket

• The type of data they transmit

• The length of the cable

Where should plenum cables ideally be used?

• In open air environments

• In underground tunnels

• In plenum spaces with open air flow

• In outdoor settings

What is a key safety feature of plenum cables?

• They are resistant to electrical interference

• They are waterproof

• They do not produce toxic fumes when burned

• They are cheaper than other cables

What is a major drawback of non-plenum cables?

• They are not compatible with most devices

• They are not as fire retardant

• They are more expensive

• They are difficult to install

What does CMR stand for in the context of network cables?

• Communications Multi-purpose Riser

• Cable Management Riser

• Cable Multi-purpose Riser

• Communications Management Riser

Where are CMR cables typically installed?

• In underwater settings

• In outdoor environments

• Vertically between floors

• Horizontally along walls

What is the primary use of CM cables?

• For outdoor installations

• For connecting computers to wall jacks

• For high-speed data transmission

• For underwater applications

Which type of cable is the least expensive?

• Non-plenum cables

• CM cables

• CMR cables

• Plenum cables

Which cable type has the highest safety standards?

• CM cables

• CMR cables

• Plenum cables

• Non-plenum cables

What is a common application for CM cables?

• Connecting network devices in rooms

• Outdoor network setups

• Running through plenum spaces

• Vertical installations between floors
