1
00:00:07,565 --> 00:00:08,398
- In this sub-lesson,

2
00:00:08,398 --> 00:00:11,880
we're going to talk about
network cabling tools.

3
00:00:11,880 --> 00:00:14,280
And we're gonna break it
down into two categories.

4
00:00:14,280 --> 00:00:16,350
The first is the patch cable,

5
00:00:16,350 --> 00:00:20,430
that smaller cable that
connects your PC or your laptop

6
00:00:20,430 --> 00:00:23,400
to the RJ45 jack on the wall.

7
00:00:23,400 --> 00:00:25,950
The tools we'll use to build a patch cable

8
00:00:25,950 --> 00:00:29,520
include a wire stripper, a crimper,

9
00:00:29,520 --> 00:00:33,300
RJ45 plugs which go on
the ends of the cable,

10
00:00:33,300 --> 00:00:35,850
and also a patch tester
which will test and make sure

11
00:00:35,850 --> 00:00:39,510
we have continuity for
each pin within the cable.

12
00:00:39,510 --> 00:00:42,660
The second category is longer cable runs.

13
00:00:42,660 --> 00:00:44,970
Cable runs that might
go from the server room,

14
00:00:44,970 --> 00:00:47,820
from a patch panel, all
the way through the ceiling

15
00:00:47,820 --> 00:00:51,630
and through the walls
down to the RJ45 jack

16
00:00:51,630 --> 00:00:53,640
which is near your workstation.

17
00:00:53,640 --> 00:00:57,330
And the tools we'll use for
that include a wire stripper,

18
00:00:57,330 --> 00:01:01,050
a punch-down tool, and a cable certifier

19
00:01:01,050 --> 00:01:04,860
to make sure that the entire
run is working properly

20
00:01:04,860 --> 00:01:08,790
and that all the wires inside
the cable are working as well.

21
00:01:08,790 --> 00:01:13,140
If you want to build a
patch cable such as this,

22
00:01:13,140 --> 00:01:15,510
you'll need a couple
tools at your disposal.

23
00:01:15,510 --> 00:01:16,920
First you'll need a good cutter

24
00:01:16,920 --> 00:01:18,900
so you can cut into the cable,

25
00:01:18,900 --> 00:01:23,100
and cut off a nice sharp
piece of the cable.

26
00:01:23,100 --> 00:01:24,870
So a good cutter is important.

27
00:01:24,870 --> 00:01:27,840
But then, to get this plastic sheath off,

28
00:01:27,840 --> 00:01:29,910
to get this PVC off of here,

29
00:01:29,910 --> 00:01:32,430
you're gonna wanna have
a good wire stripper.

30
00:01:32,430 --> 00:01:34,800
Now, you can use a lot of
different tools for this,

31
00:01:34,800 --> 00:01:37,230
but the wire stripper is my choice

32
00:01:37,230 --> 00:01:40,260
and it's on the exam objective,
so you should know it.

33
00:01:40,260 --> 00:01:43,533
And basically you open it up
and you put the cable inside.

34
00:01:46,560 --> 00:01:47,730
And this is a little bit more difficult

35
00:01:47,730 --> 00:01:49,530
because I already had stripped this.

36
00:01:50,910 --> 00:01:53,010
And then you just run it in a circle

37
00:01:53,010 --> 00:01:57,153
until you can get that PVC off of there.

38
00:01:58,170 --> 00:02:00,300
You don't want to go too far

39
00:02:00,300 --> 00:02:04,440
because you don't want to
cut into the wires inside,

40
00:02:04,440 --> 00:02:07,473
you just want to take the
plastic PVC jacket off.

41
00:02:10,170 --> 00:02:11,043
And there you go.

42
00:02:13,980 --> 00:02:16,350
And you can also use the
thread that they give you

43
00:02:16,350 --> 00:02:20,220
to cut longer distances of the PVC.

44
00:02:20,220 --> 00:02:22,140
So a good wire stripper is important,

45
00:02:22,140 --> 00:02:25,500
that has an edge on there,
that you can adjust,

46
00:02:25,500 --> 00:02:28,860
that can help you to cut
these nice and evenly

47
00:02:28,860 --> 00:02:32,010
without going into the copper wires.

48
00:02:32,010 --> 00:02:34,710
You don't want to mess with
the copper wires there.

49
00:02:34,710 --> 00:02:36,393
So a wire stripper's first,

50
00:02:37,590 --> 00:02:40,590
and then you have to apply,

51
00:02:40,590 --> 00:02:43,110
you have to cut the wires
and then you have to

52
00:02:43,110 --> 00:02:47,490
arrange them properly and
place them into the RJ45 plug.

53
00:02:47,490 --> 00:02:49,320
And maybe I'll show that
in a different video,

54
00:02:49,320 --> 00:02:51,060
put that on my website or something,

55
00:02:51,060 --> 00:02:56,060
but for now, the RJ45 plug,
you can buy these in bulk.

56
00:02:57,060 --> 00:02:59,280
The wires go inside that,

57
00:02:59,280 --> 00:03:02,700
and then you have to crimp
the plug onto the cable.

58
00:03:02,700 --> 00:03:06,300
And the reason for that is
because you have some teeth here.

59
00:03:06,300 --> 00:03:09,030
See if we can see this a little better.

60
00:03:09,030 --> 00:03:11,010
There's some teeth on here

61
00:03:11,010 --> 00:03:16,010
that are meant to bite down
onto the plastic jacket.

62
00:03:17,100 --> 00:03:18,970
And so what happens is

63
00:03:20,880 --> 00:03:22,390
you take this crimping tool

64
00:03:23,550 --> 00:03:26,640
and you put the plug in there

65
00:03:26,640 --> 00:03:29,853
and tighten it until it crimps,

66
00:03:30,870 --> 00:03:32,640
and that'll apply those teeth

67
00:03:32,640 --> 00:03:36,090
that'll have those bite
down into the wires.

68
00:03:36,090 --> 00:03:41,090
So this is an RJ45 crimper,
and here's a RJ11 also.

69
00:03:42,780 --> 00:03:46,053
So you just squeeze it until it crimps it.

70
00:03:46,920 --> 00:03:49,260
And this is just another crimper.

71
00:03:49,260 --> 00:03:51,813
Always have a couple around
just in case one fails.

72
00:03:53,460 --> 00:03:55,920
Then you use a cable tester.

73
00:03:55,920 --> 00:04:00,540
This is a patch tester, and
it has two RJ45 ports on it.

74
00:04:00,540 --> 00:04:03,900
And you just plug both
sides of your patch cable

75
00:04:03,900 --> 00:04:05,160
once you've made it.

76
00:04:05,160 --> 00:04:06,810
Or if you wanna test
one that you're not sure

77
00:04:06,810 --> 00:04:07,830
if it works or not, you know,

78
00:04:07,830 --> 00:04:11,040
if you have a patch from
a computer to an RJ45 jack

79
00:04:11,040 --> 00:04:13,800
or a patch from a patch panel to a switch,

80
00:04:13,800 --> 00:04:15,360
you can test that with this.

81
00:04:15,360 --> 00:04:18,510
Just plug both ends in and
then test by pressing a button.

82
00:04:18,510 --> 00:04:20,100
And it'll test each pin.

83
00:04:20,100 --> 00:04:23,130
Pin one, pin two, pin three, pin four,

84
00:04:23,130 --> 00:04:25,230
five, six, seven, eight.

85
00:04:25,230 --> 00:04:28,200
You know, let's say you have
pin one and three lit up,

86
00:04:28,200 --> 00:04:29,610
then you know you have a problem.

87
00:04:29,610 --> 00:04:31,740
Something was miswired on one of these.

88
00:04:31,740 --> 00:04:34,110
Or if one doesn't light up at all,

89
00:04:34,110 --> 00:04:36,330
then you know that pin is
not getting connectivity.

90
00:04:36,330 --> 00:04:38,970
So the patch tester can tell you a lot.

91
00:04:38,970 --> 00:04:42,060
And you're looking at
white-orange, orange,

92
00:04:42,060 --> 00:04:46,800
white-green, blue, white-blue, green,

93
00:04:46,800 --> 00:04:50,553
white-brown, brown. The standard 568B.

94
00:04:51,750 --> 00:04:55,200
Here's a really important
tech tip for you.

95
00:04:55,200 --> 00:04:57,120
Make sure you test.

96
00:04:57,120 --> 00:04:59,400
This is for everything
you do in computers.

97
00:04:59,400 --> 00:05:02,280
Test it, make sure it works properly.

98
00:05:02,280 --> 00:05:04,560
And this especially applies to cabling.

99
00:05:04,560 --> 00:05:07,230
You want to use the correct testing tools

100
00:05:07,230 --> 00:05:10,050
for the particular type
of cable you're making.

101
00:05:10,050 --> 00:05:12,570
Make sure you test it
after you build that cable

102
00:05:12,570 --> 00:05:14,040
or run that cable line.

103
00:05:14,040 --> 00:05:16,260
And apply that method of thinking

104
00:05:16,260 --> 00:05:19,350
to everything you do in the IT world.

105
00:05:19,350 --> 00:05:21,420
Now, let's say you're
doing a longer distance run

106
00:05:21,420 --> 00:05:26,420
from, say, an RJ45 jack to a patch panel.

107
00:05:26,430 --> 00:05:29,430
Well, you're gonna need a punch-down tool.

108
00:05:29,430 --> 00:05:32,730
This guy punches down to those ports

109
00:05:32,730 --> 00:05:35,070
on the punch panel or on the jacks

110
00:05:35,070 --> 00:05:37,590
and attaches those wires permanently.

111
00:05:37,590 --> 00:05:39,330
This is a punch-down device

112
00:05:39,330 --> 00:05:41,610
and you can use it with 110 blocks,

113
00:05:41,610 --> 00:05:43,320
that's what it's meant to be used for.

114
00:05:43,320 --> 00:05:46,170
They also have these
for 66 blocks for Telco.

115
00:05:46,170 --> 00:05:51,170
But this is a 110-block
tool for punching down.

116
00:05:52,680 --> 00:05:54,210
And here's an example of a jack

117
00:05:54,210 --> 00:05:56,400
that you might install
for a surface mount.

118
00:05:56,400 --> 00:06:00,750
And you can see here,
this is a CAT 5E jack,

119
00:06:00,750 --> 00:06:02,850
and that's the RJ45 connection.

120
00:06:02,850 --> 00:06:04,890
That's where the patch, excuse me,

121
00:06:04,890 --> 00:06:08,070
that's where the patch
cable would plug into.

122
00:06:08,070 --> 00:06:09,423
And then if you look here,

123
00:06:10,320 --> 00:06:13,290
you see that you would plug
in all the individual wires,

124
00:06:13,290 --> 00:06:15,630
you would punch them down to this

125
00:06:15,630 --> 00:06:17,250
and it's all color coded for you.

126
00:06:17,250 --> 00:06:18,083
If you're using,

127
00:06:18,083 --> 00:06:21,453
whether you're using
the 568B or A standard.

128
00:06:22,440 --> 00:06:25,890
And then finally you have a tracing tool.

129
00:06:25,890 --> 00:06:29,940
This is an inductive amplifier.

130
00:06:29,940 --> 00:06:32,130
And the inductive amplifier has a tip here

131
00:06:32,130 --> 00:06:36,363
where you can check for actual wires.

132
00:06:38,340 --> 00:06:40,530
And basically what this does is it looks,

133
00:06:40,530 --> 00:06:43,440
it traces the tone that
you may have generated

134
00:06:43,440 --> 00:06:44,610
somewhere else.

135
00:06:44,610 --> 00:06:47,250
You may have generated
tone from a patch panel

136
00:06:47,250 --> 00:06:48,870
or from another jack,

137
00:06:48,870 --> 00:06:51,960
because you're not sure where a cable is

138
00:06:51,960 --> 00:06:53,280
that's giving you trouble.

139
00:06:53,280 --> 00:06:55,560
And you know, you might
have a bunch of cables.

140
00:06:55,560 --> 00:06:58,470
You might have a hundred
cables that you need to test.

141
00:06:58,470 --> 00:07:01,320
This guy will trace that
tone that you generate.

142
00:07:01,320 --> 00:07:02,850
And you can use a lot of different items

143
00:07:02,850 --> 00:07:04,623
as a tone generator,

144
00:07:05,820 --> 00:07:09,960
including a cable certifier

145
00:07:09,960 --> 00:07:12,270
or just a plain old tone generator.

146
00:07:12,270 --> 00:07:13,530
But this will trace that.

147
00:07:13,530 --> 00:07:14,790
And it's got a little speaker here

148
00:07:14,790 --> 00:07:18,693
so you can hear the noise once
it finds the actual cable.

149
00:07:20,670 --> 00:07:22,740
And speaking of that tone generator,

150
00:07:22,740 --> 00:07:25,740
most cable certifiers or cable testers,

151
00:07:25,740 --> 00:07:27,810
like the one shown in this image

152
00:07:27,810 --> 00:07:30,423
have built-in tone generators.

153
00:07:31,320 --> 00:07:35,460
And you use those cable certifiers to test

154
00:07:35,460 --> 00:07:39,870
from a jack like this to the patch panel.

155
00:07:39,870 --> 00:07:42,270
So you wanna check all your
punch-downs that you did.

156
00:07:42,270 --> 00:07:44,280
So you use the cable certifier tool.

157
00:07:44,280 --> 00:07:46,920
You'll plug one end into
the patch panel port

158
00:07:46,920 --> 00:07:49,920
and the other end into the
jack that you've installed.

159
00:07:49,920 --> 00:07:51,870
And you can generate tone

160
00:07:51,870 --> 00:07:54,090
or you could do a pin-by-pin test,

161
00:07:54,090 --> 00:07:56,970
which is recommended for
actual cable certifying.

162
00:07:56,970 --> 00:07:58,620
You do the pin-by-pin test to make sure

163
00:07:58,620 --> 00:08:00,690
all eight pins have continuity.

164
00:08:00,690 --> 00:08:03,510
And so that's known as a cable
tester or a cable certifier.

165
00:08:03,510 --> 00:08:05,640
So that's some of the
tools for twisted pair.

166
00:08:05,640 --> 00:08:07,260
Take a look at some of these online,

167
00:08:07,260 --> 00:08:09,660
take a look into some of
your, maybe in a store,

168
00:08:09,660 --> 00:08:11,520
and look at what people have to offer.

169
00:08:11,520 --> 00:08:16,440
If you go to your electronic
supplier or electrical supplier

170
00:08:16,440 --> 00:08:18,810
you'll probably see a lot
of these tools out there.

171
00:08:18,810 --> 00:08:21,390
And take a look on, you
know, your shopping portals

172
00:08:21,390 --> 00:08:24,603
and see what's out there
as far as punch-down tools,

173
00:08:26,280 --> 00:08:31,280
RJ45 jacks, and patch panels,
and inductive amplifiers,

174
00:08:33,120 --> 00:08:35,880
which, by the way, have a lot of names.

175
00:08:35,880 --> 00:08:37,590
You have the tone generator,

176
00:08:37,590 --> 00:08:40,200
which is that device that creates tone

177
00:08:40,200 --> 00:08:41,730
whether it's your cable certifier

178
00:08:41,730 --> 00:08:44,520
or just a tone-making tool,

179
00:08:44,520 --> 00:08:46,770
and then you have the inductive amplifier.

180
00:08:46,770 --> 00:08:49,383
It's also known as a Fox & Hound kit.

181
00:08:50,340 --> 00:08:51,630
You know, because they're
chasing each other,

182
00:08:51,630 --> 00:08:53,130
you're chasing up the signal,

183
00:08:53,130 --> 00:08:55,350
you're usually looking
through hundreds of wires

184
00:08:55,350 --> 00:08:57,000
or what have you.

185
00:08:57,000 --> 00:09:01,140
And it's also known as
a tone and probe kit.

186
00:09:01,140 --> 00:09:02,820
So the tone generator makes the tone

187
00:09:02,820 --> 00:09:04,113
and this probes for it.

188
00:09:05,010 --> 00:09:05,880
This probes for it.

189
00:09:05,880 --> 00:09:10,880
So, you might even see
it listed as toner probe,

190
00:09:11,130 --> 00:09:12,990
which I never use that term

191
00:09:12,990 --> 00:09:14,910
but you might see that out there.

192
00:09:14,910 --> 00:09:17,400
But generally, scientifically,

193
00:09:17,400 --> 00:09:19,260
this is known as an inductive amplifier.

194
00:09:19,260 --> 00:09:22,020
It finds the tone that you generate.

195
00:09:22,020 --> 00:09:25,260
So there you go. Some
twisted pair cabling tools.

196
00:09:25,260 --> 00:09:27,110
And so that's it for this sub-lesson.
