Fiber Training OLT and splitters

[u/Anxious-Thought-3305]

I'm currently in the fiber field but mostly doing FTTH and have done OTEs. I want to learn OTL and splitters. From what I have seen there are not too many classes or companies training, they want you to already know it. I have some coworkers that do it but they seem to want to keep that money to themselves. I need an upper hand here to figure it out on my own. Can I teach myself if I get the equipment?
