Do you happen to have a list of the CompTIA objectives and which videos to watch that correspond to those? I did not pass my first test and I'm going to go back through your videos. However, It would be easy to look at the objectives that I missed and know which videos I should watch. Thanks!

+Daniel Otten My videos are numbered to match the CompTIA exam objectives, so it should be easy to cross-reference.

+Professor Messer thank you. I missed that somehow!

great video

For CWDM when you say "uses 3.125 Gbps/sec carriers at four different wavelengths" do you mean that 3.125gbps is the full speed or 3.125 x 4? each wavelength is that fast?

[@7mzsZyns]

I think its 4*3.1 Gbps
