1
00:00:06,420 --> 00:00:09,180
- Let's go ahead now
and build patch cables.

2
00:00:09,180 --> 00:00:11,220
Now, usually, you would use

3
00:00:11,220 --> 00:00:13,200
patch cables that you purchase.

4
00:00:13,200 --> 00:00:16,530
It's a lot easier and
they're relatively cheap.

5
00:00:16,530 --> 00:00:18,840
We use these patch cables
to connect computers

6
00:00:18,840 --> 00:00:20,790
to RJ45 jacks,

7
00:00:20,790 --> 00:00:22,800
and also to connect,

8
00:00:22,800 --> 00:00:25,530
uh, switches to patch panels.

9
00:00:25,530 --> 00:00:27,450
And there's varying other uses as well,

10
00:00:27,450 --> 00:00:28,920
but those are the main ones.

11
00:00:28,920 --> 00:00:30,240
Usually, you'd buy these

12
00:00:30,240 --> 00:00:32,880
and they're known as
straight-through patch cables

13
00:00:32,880 --> 00:00:35,460
because they're wired the same way

14
00:00:35,460 --> 00:00:36,693
on both ends,

15
00:00:37,800 --> 00:00:40,320
with the 568B standard.

16
00:00:40,320 --> 00:00:43,350
However, you might be called
upon to create a patch cable.

17
00:00:43,350 --> 00:00:45,870
Let's say, you need to
do a custom connection

18
00:00:45,870 --> 00:00:46,830
or let's say you just

19
00:00:46,830 --> 00:00:49,590
didn't have any of these
patch cables available.

20
00:00:49,590 --> 00:00:52,140
Well, if so, then you'd
need all this stuff here.

21
00:00:52,140 --> 00:00:53,580
You'd need cable,

22
00:00:53,580 --> 00:00:54,510
and I've already cut

23
00:00:54,510 --> 00:00:57,033
a six-foot length to make a patch cable,

24
00:00:57,960 --> 00:00:59,070
good cutter

25
00:00:59,070 --> 00:01:00,810
and wire stripper, just like with

26
00:01:00,810 --> 00:01:02,550
the last sub-lesson

27
00:01:02,550 --> 00:01:05,673
with the patch panel and
RJ45 Jack connections.

28
00:01:06,570 --> 00:01:07,920
Then you would need

29
00:01:07,920 --> 00:01:09,870
RJ45 plugs,

30
00:01:09,870 --> 00:01:11,493
which go on the end,

31
00:01:12,750 --> 00:01:15,000
on each end of the cable,

32
00:01:15,000 --> 00:01:17,700
which we will strip and

33
00:01:17,700 --> 00:01:19,380
open up the wires the same way we did

34
00:01:19,380 --> 00:01:20,880
in the last sub-lesson.

35
00:01:20,880 --> 00:01:24,600
And then you would need
a crimper (crimper snaps)

36
00:01:24,600 --> 00:01:27,870
to crimp the RJ45 plugs onto the cable.

37
00:01:27,870 --> 00:01:30,180
Finally, a tester to test your cable

38
00:01:30,180 --> 00:01:32,430
and make sure all the wires are correct.

39
00:01:32,430 --> 00:01:35,940
So we're gonna use all this
stuff and we'll start it now.

40
00:01:35,940 --> 00:01:38,700
So first step, we already
cut a length of cable

41
00:01:38,700 --> 00:01:40,830
and we're gonna do the
same thing that we did

42
00:01:40,830 --> 00:01:41,850
in the last sub-lesson.

43
00:01:41,850 --> 00:01:42,730
We're going to

44
00:01:45,720 --> 00:01:48,300
take off some of the PVC jacket.

45
00:01:48,300 --> 00:01:50,550
Don't wanna cut in too far,

46
00:01:50,550 --> 00:01:52,600
'Cause we don't wanna cut into the wires.

47
00:01:55,380 --> 00:01:57,633
And expose our eight wires.

48
00:02:02,700 --> 00:02:04,410
And we're going to

49
00:02:04,410 --> 00:02:07,350
set these up in the 568B order,

50
00:02:07,350 --> 00:02:08,370
which is

51
00:02:08,370 --> 00:02:09,750
White/Orange, Orange,

52
00:02:09,750 --> 00:02:11,040
White/Green, Blue,

53
00:02:11,040 --> 00:02:12,420
White/Blue, Green,

54
00:02:12,420 --> 00:02:13,773
and White/Brown, Brown.

55
00:02:15,750 --> 00:02:17,130
And you wanna try to

56
00:02:17,130 --> 00:02:18,220
put them in order

57
00:02:19,170 --> 00:02:21,940
and then straighten them
out as much as possible

58
00:02:23,670 --> 00:02:25,500
by bending them

59
00:02:25,500 --> 00:02:28,000
until we have them all in
order and somewhat flat.

60
00:02:29,520 --> 00:02:31,380
Okay, and at this point I've

61
00:02:31,380 --> 00:02:34,830
adjusted these so they're
in order for 568B,

62
00:02:34,830 --> 00:02:37,290
and you really gotta work 'em,

63
00:02:37,290 --> 00:02:39,600
and do 'em one at a time,

64
00:02:39,600 --> 00:02:40,750
and keep bending

65
00:02:41,970 --> 00:02:43,023
and straightening.

66
00:02:44,430 --> 00:02:46,950
And then what we're gonna
do is we're gonna cut them

67
00:02:46,950 --> 00:02:48,483
and cut them flat,

68
00:02:49,440 --> 00:02:52,290
so that there's an edge about here.

69
00:02:52,290 --> 00:02:53,670
And you wanna have about

70
00:02:53,670 --> 00:02:55,290
maybe a quarter inch of

71
00:02:55,290 --> 00:02:59,160
exposed wires outside the PVC jacket,

72
00:02:59,160 --> 00:03:00,810
and you want to cut 'em straight.

73
00:03:02,010 --> 00:03:03,570
And then immediately after

74
00:03:03,570 --> 00:03:04,780
we're going to put

75
00:03:05,670 --> 00:03:07,920
the RJ45 plug on there

76
00:03:07,920 --> 00:03:11,160
and crimp it on, it's all
kind of done in one step.

77
00:03:11,160 --> 00:03:12,983
So (cutter clicks) we'll take a cutter.

78
00:03:14,430 --> 00:03:16,293
Place these in like so.

79
00:03:20,640 --> 00:03:21,900
Make sure they're right.

80
00:03:21,900 --> 00:03:22,950
White/Orange, Orange,

81
00:03:22,950 --> 00:03:23,820
White/Green, Blue,

82
00:03:23,820 --> 00:03:24,660
White/Blue, Green,

83
00:03:24,660 --> 00:03:26,040
White/Brown, Brown.

84
00:03:26,040 --> 00:03:27,160
Hold on tight

85
00:03:28,560 --> 00:03:31,853
and make the cut. (Cutter clicks)

86
00:03:34,620 --> 00:03:36,090
Then we take our plug

87
00:03:36,090 --> 00:03:37,140
and we put it on,

88
00:03:37,140 --> 00:03:38,550
and we want the

89
00:03:38,550 --> 00:03:40,563
tab to be facing down.

90
00:03:44,070 --> 00:03:45,813
Stick those wires in.

91
00:03:47,820 --> 00:03:49,500
And once we get them all the way in,

92
00:03:49,500 --> 00:03:51,510
and we want them to be flush over here,

93
00:03:51,510 --> 00:03:52,590
then we can crimp it

94
00:03:52,590 --> 00:03:55,720
by sticking the RJ45 plug into the crimper

95
00:03:56,580 --> 00:03:57,513
and tightening.

96
00:03:59,010 --> 00:04:00,870
And you don't need too much pressure,

97
00:04:00,870 --> 00:04:03,720
just until (crimper clicks)
the crimper stops clicking,

98
00:04:03,720 --> 00:04:06,303
or at least, uh, finishes moving.

99
00:04:07,740 --> 00:04:09,630
And make sure it's secure.

100
00:04:09,630 --> 00:04:11,930
Then we'll do the same
thing on the other end.

101
00:04:13,808 --> 00:04:15,270
And like I say, about a quarter inch,

102
00:04:15,270 --> 00:04:16,470
maybe a little more

103
00:04:16,470 --> 00:04:18,990
close between a quarter
inch and a half inch

104
00:04:18,990 --> 00:04:20,550
we cut this off.

105
00:04:20,550 --> 00:04:21,870
You don't wanna do too much

106
00:04:21,870 --> 00:04:23,910
because you don't want
too much exposed wires.

107
00:04:23,910 --> 00:04:26,430
You wanna have the twists
on the cable length

108
00:04:26,430 --> 00:04:28,830
go as close to the plug as possible,

109
00:04:28,830 --> 00:04:30,450
but you don't wanna do it too short,

110
00:04:30,450 --> 00:04:31,830
because you wanna get those wires

111
00:04:31,830 --> 00:04:34,245
all the way to the edge of the plug.

112
00:04:34,245 --> 00:04:36,393
(crimper clicks) So we'll cut this guy.

113
00:04:38,130 --> 00:04:40,233
Hold on very carefully,

114
00:04:42,060 --> 00:04:43,053
a little shorter.

115
00:04:44,189 --> 00:04:45,900
(crimper clicks)

116
00:04:45,900 --> 00:04:48,780
Make sure you got a nice flat cut.

117
00:04:48,780 --> 00:04:50,550
Hold onto it.

118
00:04:50,550 --> 00:04:51,753
Put the plug on.

119
00:04:53,580 --> 00:04:55,680
And you wanna try to
get that plastic jacket

120
00:04:55,680 --> 00:04:57,933
underneath the tooth that's here.

121
00:04:58,800 --> 00:05:00,990
You wanna get it inside
there so when we crimp it,

122
00:05:00,990 --> 00:05:03,270
it crimps onto the plastic jacket,

123
00:05:03,270 --> 00:05:05,580
that blue jacket, and not

124
00:05:05,580 --> 00:05:07,170
the

125
00:05:07,170 --> 00:05:08,973
wires themselves.

126
00:05:10,380 --> 00:05:12,363
Stick it in, (crimper clicks) crimp it.

127
00:05:14,550 --> 00:05:15,453
And it looks good.

128
00:05:17,880 --> 00:05:19,770
And so this was a quick build.

129
00:05:19,770 --> 00:05:22,080
Uh, this particular cable's a little tough

130
00:05:22,080 --> 00:05:25,590
because it has that
plastic separator in it.

131
00:05:25,590 --> 00:05:27,390
And that could be a little
difficult to work with,

132
00:05:27,390 --> 00:05:29,550
so if you get cable and you
need to make patch cables

133
00:05:29,550 --> 00:05:30,383
you might wanna get one

134
00:05:30,383 --> 00:05:32,940
without the plastic
separator, if possible,

135
00:05:32,940 --> 00:05:35,280
But it works. You can fit it in there.

136
00:05:35,280 --> 00:05:36,183
And, uh,

137
00:05:37,290 --> 00:05:38,640
as you can see here

138
00:05:38,640 --> 00:05:41,400
we have the white orange on the left

139
00:05:41,400 --> 00:05:42,720
of each cable.

140
00:05:42,720 --> 00:05:47,103
So each connection is wired to 568B.

141
00:05:48,120 --> 00:05:49,710
And we're gonna test that right now

142
00:05:49,710 --> 00:05:51,243
by using our patch tester.

143
00:05:52,380 --> 00:05:53,793
Plug each end in.

144
00:05:57,060 --> 00:05:59,733
And we test this just by
pressing the test button.

145
00:06:01,020 --> 00:06:03,360
Press test and

146
00:06:03,360 --> 00:06:06,060
you can see the lights go on

147
00:06:06,060 --> 00:06:07,890
for pin 1,

148
00:06:07,890 --> 00:06:08,970
pin 2,

149
00:06:08,970 --> 00:06:09,803
pin 3,

150
00:06:09,803 --> 00:06:11,010
4, 5,

151
00:06:11,010 --> 00:06:11,843
6,

152
00:06:11,843 --> 00:06:13,440
7, 8.

153
00:06:13,440 --> 00:06:14,310
And it's all good.

154
00:06:14,310 --> 00:06:15,570
So,

155
00:06:15,570 --> 00:06:16,950
for a straight-through cable,

156
00:06:16,950 --> 00:06:19,563
for your standard patch
cable, that's what you want.

157
00:06:20,850 --> 00:06:22,800
And so this test's good.

158
00:06:22,800 --> 00:06:25,203
And boom, we've got a Cat6 patch cable.

159
00:06:27,270 --> 00:06:29,250
Place this to the side.

160
00:06:29,250 --> 00:06:31,560
Now you may also be called upon

161
00:06:31,560 --> 00:06:35,010
to create a crossover cable.

162
00:06:35,010 --> 00:06:39,990
And a crossover cable
uses 568B on one end,

163
00:06:39,990 --> 00:06:42,813
and the older 568A on the other end.

164
00:06:43,680 --> 00:06:45,513
And here we have an example of that.

165
00:06:48,930 --> 00:06:52,080
And quite often I'll use
orange cables to show

166
00:06:52,080 --> 00:06:53,250
crossover cables.

167
00:06:53,250 --> 00:06:54,970
And you can see on this connector

168
00:06:55,860 --> 00:06:58,650
the leftmost pins are orange,

169
00:06:58,650 --> 00:07:00,300
and that's 568B,

170
00:07:00,300 --> 00:07:01,470
and on this connector,

171
00:07:01,470 --> 00:07:04,470
the leftmost pins are green.

172
00:07:04,470 --> 00:07:06,420
That's 568A.

173
00:07:06,420 --> 00:07:09,510
So we could use a cable like
this to connect two computers

174
00:07:09,510 --> 00:07:11,430
directly together

175
00:07:11,430 --> 00:07:14,520
or two other like devices
directly together,

176
00:07:14,520 --> 00:07:16,560
like two routers or two switches.

177
00:07:16,560 --> 00:07:18,750
Although nowadays that's
not usually necessary

178
00:07:18,750 --> 00:07:21,780
because you have
auto-negotiation of the ports

179
00:07:21,780 --> 00:07:22,890
and they can, uh,

180
00:07:22,890 --> 00:07:25,710
tell what type of cable
you have connected.

181
00:07:25,710 --> 00:07:28,710
But you can also test these guys.

182
00:07:28,710 --> 00:07:33,710
We could place these plugs
in here. (plugs click)

183
00:07:33,780 --> 00:07:37,590
And, basically, what a crossover cable is,

184
00:07:37,590 --> 00:07:39,900
is a cable that crosses

185
00:07:39,900 --> 00:07:43,590
the orange and green pairs.

186
00:07:43,590 --> 00:07:46,803
So if we press the button,
we get 1 goes to 3.

187
00:07:49,050 --> 00:07:53,700
White/Orange is the first pin in 568B,

188
00:07:53,700 --> 00:07:56,880
but it's the third pin in 568A,

189
00:07:56,880 --> 00:07:58,770
2 crosses to 6,

190
00:07:58,770 --> 00:08:00,153
that's the Orange pin.

191
00:08:02,160 --> 00:08:04,770
And vice versa, 3 crosses to 1,

192
00:08:04,770 --> 00:08:07,590
that's the White/Green,

193
00:08:07,590 --> 00:08:10,020
because it's the third pin and 568B,

194
00:08:10,020 --> 00:08:12,483
it's the first pin in 568A.

195
00:08:13,650 --> 00:08:16,803
4 goes to 4, 5 goes to
5, so Blue is normal.

196
00:08:17,670 --> 00:08:18,963
6 goes to 2,

197
00:08:20,880 --> 00:08:23,013
and that is your Green pin.

198
00:08:24,060 --> 00:08:26,610
And 7 and 8 are normal,

199
00:08:26,610 --> 00:08:27,610
those are the Brown.

200
00:08:29,190 --> 00:08:30,810
So that's how we can tell if, uh,

201
00:08:30,810 --> 00:08:33,570
this crossover cable is wired properly.

202
00:08:33,570 --> 00:08:35,820
And so this one was a molded one,

203
00:08:35,820 --> 00:08:36,693
it's orange.

204
00:08:39,180 --> 00:08:41,010
And I also have my own that I created.

205
00:08:41,010 --> 00:08:43,530
I usually keep one or
two with me in my kit,

206
00:08:43,530 --> 00:08:45,933
just in case I need to connect something.

207
00:08:47,520 --> 00:08:49,203
This one I actually built.

208
00:08:52,470 --> 00:08:54,033
And it tests fine.

209
00:08:56,370 --> 00:08:59,280
So, a little bit of a testing
with straight-through cables,

210
00:08:59,280 --> 00:09:00,550
which connect

211
00:09:00,550 --> 00:09:02,280
unlike devices,

212
00:09:02,280 --> 00:09:04,563
like a computer to a switch,

213
00:09:06,540 --> 00:09:08,470
and crossover cables

214
00:09:09,720 --> 00:09:11,790
that test like devices,

215
00:09:11,790 --> 00:09:14,070
like a computer to another computer,

216
00:09:14,070 --> 00:09:15,783
or a switch to a switch.

217
00:09:17,040 --> 00:09:19,290
And so I do have another
crimper here (crimper clicks)

218
00:09:19,290 --> 00:09:20,763
and it's just the same thing,

219
00:09:21,930 --> 00:09:23,100
whatever works,

220
00:09:23,100 --> 00:09:26,070
whatever crimps the plugs on
good for you is what you need.

221
00:09:26,070 --> 00:09:28,320
And a lot of these crimpers come with the

222
00:09:28,320 --> 00:09:30,510
RJ45 connector,

223
00:09:30,510 --> 00:09:32,850
as well as the RJ11,

224
00:09:32,850 --> 00:09:34,623
so if you're doing any telco work.

225
00:09:35,580 --> 00:09:37,050
And that cutter.

226
00:09:37,050 --> 00:09:40,200
You know a good cutter on the
crimper is really necessary.

227
00:09:40,200 --> 00:09:41,880
You could use something like this,

228
00:09:41,880 --> 00:09:44,880
but you might not get
a really straight cut.

229
00:09:44,880 --> 00:09:49,200
And so this works very
well. (crimper clicks)

230
00:09:49,200 --> 00:09:51,840
And there we have it,
our patch cable's done.

231
00:09:51,840 --> 00:09:53,700
We've got a Cat6

232
00:09:53,700 --> 00:09:56,433
six-foot straight-through cable.

233
00:09:57,600 --> 00:09:59,820
Unshielded twisted pair.

234
00:09:59,820 --> 00:10:02,340
And so, you know, you can
build these pretty quick.

235
00:10:02,340 --> 00:10:04,290
In real time I could make one of these in

236
00:10:04,290 --> 00:10:05,193
under,

237
00:10:06,120 --> 00:10:09,270
the fastest I ever did is
maybe, uh, two minutes.

238
00:10:09,270 --> 00:10:10,710
But again it's easier to just

239
00:10:10,710 --> 00:10:12,573
use the ones that you purchase.

240
00:10:13,950 --> 00:10:16,420
For example, these molded cables here

241
00:10:17,640 --> 00:10:21,483
which are machined and will
most likely last longer.

242
00:10:22,980 --> 00:10:25,350
But if you ever have a problem
where you suspect a problem

243
00:10:25,350 --> 00:10:29,130
with a patch cable, use one
of these RJ45 patch testers.

244
00:10:29,130 --> 00:10:32,040
And make sure that all the wires

245
00:10:32,040 --> 00:10:34,263
go across for a straight-through cable.

246
00:10:35,250 --> 00:10:36,423
Great tool to have.

247
00:10:38,310 --> 00:10:39,540
So that's it. Tools you need.

248
00:10:39,540 --> 00:10:40,593
You need your cable,

249
00:10:41,880 --> 00:10:44,103
you gotta have that cable, I'm using Cat6.

250
00:10:45,060 --> 00:10:46,323
You need your crimpers.

251
00:10:47,370 --> 00:10:49,200
Always want to have your cutter

252
00:10:49,200 --> 00:10:51,630
and your wire stripper available.

253
00:10:51,630 --> 00:10:53,580
And RJ45 plugs,

254
00:10:53,580 --> 00:10:56,070
this is, I got a hundred-pack here.

255
00:10:56,070 --> 00:10:57,570
These are for Cat6 as well.

256
00:10:57,570 --> 00:11:00,390
And remember, that
everything has to comply

257
00:11:00,390 --> 00:11:02,040
along the chain.

258
00:11:02,040 --> 00:11:05,250
If any link along the chain is less

259
00:11:05,250 --> 00:11:06,750
than Cat6,

260
00:11:06,750 --> 00:11:08,880
then the whole chain

261
00:11:08,880 --> 00:11:09,990
gets reduced

262
00:11:09,990 --> 00:11:11,340
to that lesser amount.

263
00:11:11,340 --> 00:11:12,840
So the plugs have to be good.

264
00:11:12,840 --> 00:11:14,580
The cable has to be good.

265
00:11:14,580 --> 00:11:17,250
The patch panel, the RJ45 jack,

266
00:11:17,250 --> 00:11:18,083
all of it.

267
00:11:19,500 --> 00:11:22,410
And another great tool to use.

268
00:11:22,410 --> 00:11:23,410
We have the

269
00:11:24,720 --> 00:11:26,160
Loopback Tester,

270
00:11:26,160 --> 00:11:28,200
which you can use to test

271
00:11:28,200 --> 00:11:30,660
network cards and also switches,

272
00:11:30,660 --> 00:11:31,800
really good for switches.

273
00:11:31,800 --> 00:11:33,720
If you wanna plug these into,

274
00:11:33,720 --> 00:11:35,520
say an RJ45 jack,

275
00:11:35,520 --> 00:11:37,380
it'll help you to test the switch,

276
00:11:37,380 --> 00:11:39,600
whether the port is good or not.

277
00:11:39,600 --> 00:11:42,210
There's actually a couple uses for this.

278
00:11:42,210 --> 00:11:44,100
And I talk about these more in my books

279
00:11:44,100 --> 00:11:46,080
but, uh, a great tool to have:

280
00:11:46,080 --> 00:11:48,330
RJ45 Loopback Tester.

281
00:11:48,330 --> 00:11:50,430
It's got the female and the male ends.

282
00:11:50,430 --> 00:11:52,230
So you can do a lot of
different testing with that.

283
00:11:52,230 --> 00:11:55,230
But generally used to check
switches and switch ports.

284
00:11:55,230 --> 00:11:56,610
So there you have it.

285
00:11:56,610 --> 00:11:57,960
Patch cables.

286
00:11:57,960 --> 00:12:00,090
And that pretty much sums it up.

287
00:12:00,090 --> 00:12:01,790
That's the end of this sub-lesson.
