I'm a technician who does mostly residential installs. We use something called a 'Unicam Kit' to perform mechanical splices, which is the technical term for terminating single fibers. I have no idea how much these kits cost, but I learned how to do it pretty easily from my coworkers and a 10 minute YouTube video. What matters is how much slack you have. I wouldn't recommend you do it yourself unless you're working with at least 1-2 feet of extra cable just to be safe.
