The fiber cable works and that's the most important thing (20 meters is not that long so it shouldn't be a problem). However, the light blue color of the cable is not good for a wiring closet because it blends in with regular Ethernet patch cables we use. Fiber cable requires special handling (no sharp bends, no undue stress, etc.) - there is a glass fiber in the center of it after all. All of our fiber cables are bright orange in color so we can easily identify them.

PROS: Works.

CONS: Wrong color for fiber cable. Fiber cable should be bright orange in color so it can be easily identified.

Great!
