Have you crossed the connectors? I.e. disassemble one end of each
loop, and change the order of the two fibres. Remember, FC-AL is just
like ethernet. A straight-through pair connects a device (i.e. E4500,
or A5000) only to a hub. For a direct-connect like yours, the pairs
must be crossed.

The only 2 tools you will ever need are WD-40 and duct tape. If it
moves and it shouldn't, use duct tape. If it doesn't move and it
should, use WD-40.
