Network Cables – Fire Safety PVS vs. Plenum Welcome to the Cybrary IT A+ Certification course for the CompTIA Exam, in today's lesson we are going to explore the specifications for some of our network connectors in terms of speed and transmission distances. We begin with a discussion with fire safety and that mean code compliance in terms of the materials used. After completing this lesson, you will know what a Plenum space is, what the differences is between PVS, where Plenum coated materials are required and why there is a significant distinction in how coated cabling is used. We also diagram the specs associated with each coating type and explain for example why PVC coatings are toxic and Plenum coatings are safer and under what circumstances that makes a difference. You'll also master when you must first observe fire, safety, building codes and local regulations and that is factored into your work as an A+ Certified Technician.

Hi and welcome to cyberia dot i t. My name is Anthony and I'm the local subject matter expert here For a plus. Today we're gonna be talking about some of our network connectors specifications. We're going to dive deep into some of our different types of network connector cables and their exact specifications as faras speeds and
transmission distances.
So hopefully you'll enjoy this and let's go ahead and get started. One of the first things we need to investigate is going to be the fire safety of these cables. Now, when we're talking about our fire safety, we mean how we can wire our environment so that it's up to code. While there are exact specifications that we won't
get into the exact regulations and
the exact legal specifications and fire codes, they can vary from area to area. There's a difference that's important to know between something called PVC and plenty of spaces. When we're talking about Planum, spaces were talking about the areas in our building. In our environment, that air
used more for
air circulation and for moving air around our environment. Now we're not just talking about Our air ducts were also talking about the spaces above our drop ceilings, the spaces in our walls, the spaces under our floors. All of these air considered our planum spaces. And all of these actually have tohave Clinton cables
rather than standard cables with PVC coatings.
And here's our reason we're talking about PVC cables. These there are cables, which
the plastics in them that they use are made out of this PVC material. Now this material is less expensive than planting material, and it's more. It's more often used just in standard cables that will buy from the store. But we can't really use this to wire up
our entire violent environment. We can't use this in our walls and our ceiling spaces in our floors,
because when this burns it, actually, um, it's a toxic fume. Now we can see how this can create an issue. Say,
if there was a fire in our building, firefighters or emergency responders responding to the situation or even just the environmental aspect of having a building with this PVC cable burning. Creating all these toxic fumes isn't conducive to the help of
number one, the health of the people responding to the incident or the help of the environment after all the fumes or disperse and after everything burns. So these toxic cables aren't really what we want to use, but they're cheap, and they're good for our typical daily usage, where we're just using them to plug in the couple computers or using the plug into our walls. If you pull it just
looking your laptop into a router using an Ethernet cable,
you're probably just gonna use a standard PVC coated cable you aren't is worried about. If there's a fire and that cable burns because it's just that one strand of cable it's not. Hold the cabling that's all in your house and in the walls Now. The Planum cable. Um, it's a lot less fumes when burned. A less harmful
is also fire resistant.
And this is the type of cable that we're gonna have to use if we're putting our cables and our ceilings on our walls. It is more expensive,
but in a lot of situations, especially if you're wiring a new office building, you need to check your local fire codes. You need to check local regulations as faras putting cables and buildings because a lot of times there are requirements for using this Planum type cable rather than the PVC cable. Just due to the amount of
fumes that the PVC type cable burns went. Our admits when it's burned, rather than the less fumes and the fire resistance that the planning cable has.
