1
00:00:00,360 --> 00:00:01,560
In this section of the course,

2
00:00:01,560 --> 00:00:03,810
we're going to discuss media and cabling.

3
00:00:03,810 --> 00:00:05,939
Now, when we use the term media and networking,

4
00:00:05,939 --> 00:00:08,039
we're not talking about video or audio content,

5
00:00:08,039 --> 00:00:09,330
like you might be thinking.

6
00:00:09,330 --> 00:00:11,820
Instead, media refers to the physical material

7
00:00:11,820 --> 00:00:14,520
that's going to be used to transmit data between devices.

8
00:00:14,520 --> 00:00:15,750
Now, when it comes to media,

9
00:00:15,750 --> 00:00:17,550
the most common types are copper,

10
00:00:17,550 --> 00:00:19,740
fiber, and radio frequency waves.

11
00:00:19,740 --> 00:00:22,050
For example, if you're using a Cat6A cable

12
00:00:22,050 --> 00:00:23,730
to connect your desktop to your network,

13
00:00:23,730 --> 00:00:26,520
that is a copper cable or copper-based media.

14
00:00:26,520 --> 00:00:27,930
If you're using a fiber optic connection

15
00:00:27,930 --> 00:00:29,640
to connect to your internet service provider,

16
00:00:29,640 --> 00:00:31,590
that is considered fiber media.

17
00:00:31,590 --> 00:00:33,150
Or if you're using wifi to connect

18
00:00:33,150 --> 00:00:34,770
to your smartphone to your home network,

19
00:00:34,770 --> 00:00:37,530
that's actually a radio frequency wave-based media type,

20
00:00:37,530 --> 00:00:39,030
because those invisible radio waves

21
00:00:39,030 --> 00:00:41,550
are what will be carrying our network traffic on our behalf

22
00:00:41,550 --> 00:00:43,620
or that series of ones and zeros.

23
00:00:43,620 --> 00:00:45,030
So in this section of the course,

24
00:00:45,030 --> 00:00:46,830
we'll be covering media and cabling,

25
00:00:46,830 --> 00:00:48,600
and we'll be focused mostly on Domain 1,

26
00:00:48,600 --> 00:00:49,860
or networking concepts,

27
00:00:49,860 --> 00:00:52,020
but we'll also be jumping briefly into Domain 5,

28
00:00:52,020 --> 00:00:53,730
network troubleshooting, too.

29
00:00:53,730 --> 00:00:57,000
Specifically, we'll be focused mostly on Objective 1.5,

30
00:00:57,000 --> 00:00:58,440
which states that you must be able to compare

31
00:00:58,440 --> 00:01:01,200
and contrast transmission media and transceivers.

32
00:01:01,200 --> 00:01:04,050
But we'll also briefly explore Objective 5.5,

33
00:01:04,050 --> 00:01:05,489
which states that given a scenario,

34
00:01:05,489 --> 00:01:07,260
you must be able to use the appropriate tool

35
00:01:07,260 --> 00:01:09,840
or protocol to solve networking issues.

36
00:01:09,840 --> 00:01:12,180
Now, first we're going to take a look at copper media

37
00:01:12,180 --> 00:01:13,800
and explore the different types of copper media

38
00:01:13,800 --> 00:01:14,700
and the different bandwidth

39
00:01:14,700 --> 00:01:16,830
and distance limitations for each type.

40
00:01:16,830 --> 00:01:19,080
Then we'll cover copper network connections,

41
00:01:19,080 --> 00:01:20,790
and we'll explore the different connectors that are used

42
00:01:20,790 --> 00:01:23,490
to attach a copper based media cable to the network,

43
00:01:23,490 --> 00:01:26,310
including things like RJ45, RJ11,

44
00:01:26,310 --> 00:01:28,560
F-Type, and BNC connectors.

45
00:01:28,560 --> 00:01:29,970
Next, I'm going to teach you how to create

46
00:01:29,970 --> 00:01:32,040
your own copper-based network patch cable

47
00:01:32,040 --> 00:01:34,320
using some basic tools like a cable stripper,

48
00:01:34,320 --> 00:01:36,720
a cable crimper, and a cable tester.

49
00:01:36,720 --> 00:01:38,490
After that, we'll explore the different types

50
00:01:38,490 --> 00:01:40,050
of fiber media used in our networks,

51
00:01:40,050 --> 00:01:42,750
including single-mode fiber and multi-mode fiber.

52
00:01:42,750 --> 00:01:44,820
We'll also be focused on the benefits and limitations

53
00:01:44,820 --> 00:01:46,530
of each of these different types of fiber media

54
00:01:46,530 --> 00:01:48,480
that are used inside of our networks.

55
00:01:48,480 --> 00:01:50,700
Next, we'll discuss the different fiber network connections

56
00:01:50,700 --> 00:01:53,010
that you may come across when working as a technician,

57
00:01:53,010 --> 00:01:57,990
including SC, ST, LC, MTRJ, and MTP connectors.

58
00:01:57,990 --> 00:01:59,880
After that, we'll cover the different uses

59
00:01:59,880 --> 00:02:01,830
for transceivers inside of our networks.

60
00:02:01,830 --> 00:02:03,150
Now, a transceiver is a device

61
00:02:03,150 --> 00:02:04,380
that combines both the transmission

62
00:02:04,380 --> 00:02:07,050
and receiving capabilities into a single unit,

63
00:02:07,050 --> 00:02:09,150
and this is often used to connect different media types

64
00:02:09,150 --> 00:02:11,130
like fiber and copper networks

65
00:02:11,130 --> 00:02:13,020
that you may want to convert between.

66
00:02:13,020 --> 00:02:15,180
Finally, we'll take a short quiz to see what you learned

67
00:02:15,180 --> 00:02:16,410
during this section of the course

68
00:02:16,410 --> 00:02:17,730
and review your answers to ensure

69
00:02:17,730 --> 00:02:19,320
that you know why the right answers were right

70
00:02:19,320 --> 00:02:20,970
and the wrong answers were wrong.

71
00:02:20,970 --> 00:02:23,490
So if you're ready, let's get started in our coverage

72
00:02:23,490 --> 00:02:26,040
of media and cabling in this section of the course.
