Took a BISCI short course years ago, and to date, I have pulled and terminated a total of ONE Multi-mode since.
Most of our jobs don't call for it, and if there is any on the job, it is often a back-bone done by someone else, or the carrier.
A while back the talk was that there was going to be "Fiber-to-the-desk". Turned out to be a crock... Who knows, maybe someday there will be. From what I understand, what killed the more extended use of fiber wasn't the fiber, but network equipment costs.

You can get a gigabit/second through a Cat5e cable. That requires only a single, low-cost IC and a single package of isolation transformers for termination. For a fiber, you need expensive transmitter and receiver modules to drive and terminate the fiber. Since you can already get a GBPS over cheap copper, there's really not much point to bringing a fiber to the desktop--a gigabit is already major overkill for 99+% of the applications out there. You can get all the bandwidth you need with copper, and it costs a whole lot less. So people use copper.

This reminds me of a high school in Westchester,NY that I worked in about 3 years ago, the company I was working for was doing a cleanup of their telecom closets, the school was wired with copper and fiber to every classroom, about 5-6 locations in room. Every device was on copper and all of the fiber terminations have been sitting there unused with about an inch of dust on them, I don't see fiber being used to the desktop, mostly the bandwidth it holds is used for ethernet backbones or bandwidth intensive applications in data centers. Boy would I have loved to be the one to get the contract to install all that fiber in that high school, $$CHA-CHING$$

There have been some valid points made here. Fiber optic transmission is mostly the domain of telephone and CATV companies. Fiber to the desk so to speak is not likely to become reality in the near future, as CAT5E, soon CAT6 & 7, and WiFi will dominate LAN’s.
However your local CATV and telephone companies are in a huge race to get fiber optics to the curb or in your house. First one in wins a huge prize, bandwidth domination.
I am looking into fiber because I have to run a port of our router almost a 1000 feet from the hub. My understanding of cat 5 is it's good for about a 100. although the one I am using now is about a 130.
