I don't do many fiber jobs. The last one was several years ago and I'm a little rusty. What type of fiber do I need to go 250 feet in a pvc conduit under a concrete floor in a shop? I was looking at an old catalog I have and thought indoor/outdoor type, but I called a fiber sales company and they want to sell me loose tube. Price is twice as much. After that decision, I know that the media converters will dictate the style of connectors, multi or single mode and 62.5 or 50 micron.

Thanks!
Jim
