Our network is Cat 5/5e, with two sections of fiber optic cable to run between buildings. Recently one of these fiber cables stopped working, I suspect a cable break or perhaps one end needs to be re-terminated. I'm experienced with troubleshooting and fixing cat5, but have never worked with fiber.
Opinion question: Is it worthwhile for me to take a class and buy the tools and learn how to do this myself, or just leave it to outside contractors? we will probably be using more fiber in the near future, but I don't anticipate it being a huge amount. I've "fixed" the fiber problem by running Cat 5 to connect the two buildings, just like the fiber does. It works, but is not optimal.
