Video Description

Fiber Cables – Singles Mode vs. Multi-Mode Next we examine cables in more depth and we begin with fiber cables. Fiber cables transmit data with light and are not susceptible to environmental changes the way other cabling does. You'll learn all the advantages of using fiber, such as what the greater distances are, why signal boosters aren't necessary, what Multi-Mode Fiber is and how it performs differently in terms of how much data can be transmitted and how much further than Single Mode, and where you would use it.

Video Transcription

00:04
Now that we know about our
00:06
our fire aspect, our fire resistance for different cables are PVC versus Planum. Let's go ahead and start talking about our cables. The first cable we're gonna dive into is going to be our fiber cable.
00:17
And you saw earlier video you saw
00:20
how we talked about that fiber cable trend doesn't transmit signals with electricity, but it actually transmit signals with light.
00:27
Now this
00:28
transmission through light
00:30
helps us when we want to set up. Backbone systems are back mon systems being the networks that carry a lot of amount of data or carried over a great distance. Such a czar Data center cables are cables that are Internet service provider may provide to us or even our intercontinental cables that transmit data
00:48
over the ocean floor from one continent to another continent. Alot of these could be used are considered backbone cables and ah, lot of them use fiber now fiber because it transmits with light, it is not susceptible to electromagnetic interference. We use the acronym E M I because there's no electricity running through this cable because it doesn't
01:07
transmit data with electricity.
01:10
It's not affected by any electromagnetic environment around it. That's not going to affect the way the that the light goat travels through the cable. It's not gonna affect the signal, so that's a big plus for us. It gives us a couple things. It lets us to transmit at a faster rate,
01:25
and it also lets his transmit at farther distances.
01:27
Now we have a couple different types of fiber cables. We already talked about the different connectors we have. We actually have different types of cables. We have something called single mode fiber abbreviated S M F. And this single mode fiber on. Lee has a single core, and it just transmits are single transmission for long distances. Some single mode
01:48
fiber lines can even carry
01:49
information up to 50 miles. This is a huge advantage, especially for these cables that are
01:55
our backbone systems. We don't have to have constant stations where we
02:00
push the signal. We don't have to have constant and boost signal Booster's. We can have one long, 50 mile cable, and if it's pushing over this single mode fiber and can go that great distance, the counterpart of this single mode fiber is something known as multi mode fiber. This multi mode fiber abbreviated M M F has a
02:20
picker
02:20
core, then single mode fiber, and this multi mode fiber can actually carry multiple rays of light for shorter distance up to 500 meters. But as we know from talking about, our other types of cables are 500 meter distance on here is actually a bit longer than our other cables can carry.
02:38
So again, our single mode fiber
02:40
single corps single single beam of light, a single data strand,
02:46
multi mode fiber, thicker core, multiple data strands, multiple beams of light but only
02:52
500 meters, as opposed to single mode fibers 50 miles backbones. Systems that are transmitting that data over super long distances will be more likely to use this single mode fiber. But our multi mode fiber will see Maur in situations where we're actually we're valuing that speed over valuing over distance, so
03:10
we're more interested in getting there
03:13
quickly. Then we are about the vast speed, so that's where we'll be using our multi mode fibre rather than our single mode fiber
