I help out my family's church with their tech stuff, and they want to protect a fiber line that was put in a while back. At the moment, the cable just goes into the rack and the terminated ends just sit exposed. Recently some work was done in the rack and the fiber lines were damaged and had to be redone.

I'd like to remove the line from the rack and place the end of the cable and the fiber to ethernet converter in an enclosure of some kind. I'm trying to find that enclosure, but I'm not sure what to call what I'm looking for. Any suggestions?
