There is a lot that goes into fiber splicing that you would not know because you have never done the job before.
1st if you're going to be a fiber splicer in house, being paid hourly you're going to be severely underpaid, but the company you work for should provide vehicles and tools and pretty much everything you need compared to a contractor who owns all his own vehicles and tools.
2nd there is a lot more you need to know about fiber than you think. It is not just prepping cable, building a case, and splicing. You need to know how fiber construction works, you need to know how fiber rings work, and how certain optics are either Omni-directional or Bi-directional, all of this is knowledge that you need to know and implement in your job as a fiber splicer.
If you're going to be a contractor it is going to take a significant investment so if you don't have at least a minimum of $60-100K to invest you might want to look into getting a job in house where they can train you and provide you with everything.
On a side note be careful who you trust in the business there are a lot of people that are not here to help you and want to see you fail.
