Mike explores the backbone connections of the internet.
- The coolest part of the internet and the part you're…probably never going to see unless you have…a really cool job, and if you get one of these jobs,…call me 'cause I would love to get a tour of some…of these places, is at the very top of the internet.…The very top of the internet is pretty much…all fiber optic cabling.…The main fiber optic standard,…this runs most of the top of the internet is called SONET.…A SONET signaling uses a particular type of optical carrier,…kind of the optical equivalent of T1, called OC lines.…The slowest OC line there is is the OC-1 and it runs…at 81.85 Mbps.…
Now there's a whole bunch of increments that go beyond that.…For example, the OC-3 line runs at exactly three times OC-1,…so it runs at about 155 Mbps.…Now if you wanted to see all the of OC carriers,…well here, let me put up a chart.…Wow, that's a lot of different OC carriers.…Now listen, don't panic trying to memorize…that entire chart for the Network Plus Exam.…If you concentrate on the first three, OC-1, OC-3,…and OC-12, you'll be perfectly fine for the Network Plus.…
