Hey Don!
At the end of the intro episode you showed a home transceiver for fiber to Ethernet. So I was wondering what would be the point of using fiber in one end if in on the Ethernet end the bandwidth is going to be limited to 100 Mbps anyway.
Also, I don't mean to be negative, but that guy Nate Copeland did not contribute in anything, and only made lame jokes and weird noises; please do not have him in the future if he is not going to contribute in anything.
Thanks!
There would be many situations where you would convert from fiber to copper. FYI saying fiber to Ethernet is not technically correct because fiber also uses Ethernet.
Ethernet is a standard means of transmitting data. Specifically 802.3 .
With that said when have you ever seen a computer with a Fiber Network Card? So at some point in the network the Fiber has to be converted over to copper.
Also Fiber equipment is very expensive. To keep costs down while enjoying the speed benefits of fiber you would only use fiber at the points in your network that you would identify as bottle necks. Mainly the core and distribution layers.
And further more, 100mb is (in today's standards) pretty low speed for a network. Pretty much every node on the LAN should be running at gigabit speed. So with everyone running at gigabit speeds having fiber on one end is a great way to deal with bottle neck issues.
Lastly, you should go and watch a CBT nugget video or an INE video. In fact go and watch any other technical training video on the net. You will see that having one of the host inserting jokes here and there makes a huge difference in information retention. The video series I mentioned all take a very technical and monotone approach to IT training. After 10 minutes of listening to the host it's very difficult to stay focused. What I like about IT pro TV is that wise cracks always brings you back in and doesn't let your brain doze off. So Nate keep the lame jokes coming.
There's a couple of reason to do so.
Let's say the the cost from the ISP is just about the same to run a Fiber Line to your business or a copper line. Fiber can easily expand capacity over copper. You would pick a fiber line run to the building then internally you would use a media converter to convert your copper network to connect to your ISP over fiber. Usually, this is how you see it happening. Here at ITProTV we have a 80Mbps connection to the ISP but internally we only run 100 Mbps to every port. Fiber is the future.
We do run fiber to our editing workstations though. This allows for each editor to work at 10Gbps to the shared storage without worrying. So in this sense We had to instead of using a media converter to connect to an existing switch, we put a 10 Gig blade in our switch with each port having dedicated 10Gbps for fast transfers to and from the editing stations.
Daniel is right it would be better if we had gig connections with non-blocking ports but the very fact is in most SMB you'll see that even the Gig ports are oversubscribed 4 to 1 or 8 to 1 or higher instead. Normally in the situation that Daniel is describing you also would have to consider things like how much internal bandwidth is there for the switch (backplane).
