1
00:00:00,080 --> 00:00:05,839
consumer Ethernet has pretty much followed the rule of each generation

2
00:00:03,520 --> 00:00:10,240
having 10 times the maximum speed of the previous one however the game is

3
00:00:08,000 --> 00:00:13,840
changing there are actually some quarter and half measures in the works yes my

4
00:00:12,559 --> 00:00:19,279
friends that's right you're going to be seeing 2.5 gigabit and 5 gigabit

5
00:00:17,199 --> 00:00:24,000
Ethernet devices popping up all over the place but why to answer we spoke to ben

6
00:00:22,080 --> 00:00:29,199
hacker and ben benson over at Intel and we'd like to thank them for their contributions to this episode as

7
00:00:26,800 --> 00:00:33,120
internet speeds get faster it's becoming clear that we're going to need something

8
00:00:30,800 --> 00:00:37,760
that is faster than the gigabit Ethernet that's supported by lots of our home

9
00:00:35,200 --> 00:00:42,480
modems and routers even if you don't have fiber to the home new versions of

10
00:00:40,160 --> 00:00:47,680
the docsis cable internet standard can support speeds beyond one gigabit per

11
00:00:44,719 --> 00:00:52,719
second in fact two gigabit connections are becoming common in tech mechas like

12
00:00:49,760 --> 00:00:56,879
south korea and japan which is all fine and good but why bother with this

13
00:00:55,120 --> 00:01:01,840
tweener stuff when you can go out and buy a 10 gigabit network card and 10

14
00:00:59,359 --> 00:01:06,960
gigabit switch today well the issue is that the 10 gigabit standard doesn't

15
00:01:04,400 --> 00:01:12,000
work very well over most of the existing Ethernet cabling that's out there so if

16
00:01:08,960 --> 00:01:14,000
you go out and buy a theoretical cable

17
00:01:12,000 --> 00:01:18,159
modem with a 10 gig port on the back of it chances are that you're going to end

18
00:01:16,000 --> 00:01:22,479
up needing to change out every network cable in your house in order to get the

19
00:01:20,240 --> 00:01:27,520
full benefit of it and in commercial installations this problem is much worse

20
00:01:25,600 --> 00:01:32,320
you see many buildings have been pre-wired with Ethernet jacks in the

21
00:01:29,360 --> 00:01:36,159
walls that use the older cat5e cable standard which was designed to handle up

22
00:01:34,320 --> 00:01:41,200
to one gigabit per second over a distance of 100 meters and for a long

23
00:01:38,479 --> 00:01:46,560
time that was just fine but 10 gigabit Ethernet requires a newer cable called

24
00:01:43,439 --> 00:01:49,600
cat6 to go 50 meters and an even higher

25
00:01:46,560 --> 00:01:52,479
end cable called cat6a with the a4

26
00:01:49,600 --> 00:01:56,799
augmented to do the full 100 meters the reason that cat5e can't carry a 10

27
00:01:55,040 --> 00:02:01,360
gigabit signal effectively over those distances is that it doesn't have as

28
00:01:58,960 --> 00:02:05,439
much protection against interference and crosstalk so what this means is that

29
00:02:03,439 --> 00:02:10,160
getting 10 gigabit to work in many places would mean ripping the old cables

30
00:02:07,759 --> 00:02:14,480
out of the wall and putting in new ones and that is alongside all of the

31
00:02:12,239 --> 00:02:19,760
equipment in the networking room and all of the client pcs that is a tough triple

32
00:02:17,760 --> 00:02:23,840
whammy to the old corporate pocketbook so the powers that be are instead

33
00:02:21,599 --> 00:02:28,400
introducing a two and a half gigabit Ethernet solution because it turns out

34
00:02:26,000 --> 00:02:33,200
that a cat 5e cable that was built to spec can actually handle a two and a

35
00:02:30,640 --> 00:02:39,120
half gigabit per second signal just fine over 100 meters and even a 5 gigabit per

36
00:02:36,239 --> 00:02:43,040
second signal will usually work the hold up was just that the industry

37
00:02:40,959 --> 00:02:47,120
doesn't like to bother rolling out a new spec for less than 10 times the previous

38
00:02:45,360 --> 00:02:51,920
speed because they typically view it as not being worth the effort it takes

39
00:02:49,120 --> 00:02:56,720
but given how excessive the 10 gigabit speed is for general consumers and the

40
00:02:54,000 --> 00:03:01,120
fact that 10 gigabit equipment is still a lot more expensive the industry has

41
00:02:59,360 --> 00:03:05,680
finally developed an interest in being able to sell faster equipment at a price

42
00:03:03,280 --> 00:03:09,840
that consumers can actually handle so faster Ethernet speeds then are going to

43
00:03:07,440 --> 00:03:14,400
have immediate benefits for enthusiasts and prosumers who want the additional

44
00:03:11,920 --> 00:03:19,760
bandwidth for things like transferring files between pcs and network attached

45
00:03:17,040 --> 00:03:23,840
storage or running home media servers as for the regular consumer

46
00:03:21,680 --> 00:03:28,400
well the benefits today might actually be limited but two and a half or five

47
00:03:26,560 --> 00:03:33,040
gigabit Ethernet jacks rolling out in computers network adapters and modems

48
00:03:30,959 --> 00:03:37,519
over the coming years means that our underlying infrastructure is going to be

49
00:03:34,720 --> 00:03:41,760
ready for future advancements like 8k streaming video to multiple household

50
00:03:39,440 --> 00:03:45,120
members and other amazing technology that makes it so we just don't actually

51
00:03:43,360 --> 00:03:48,400
have to talk to each other anymore speaking of talking to each other i want
