As a first step you probably want to fact check if you have a
"darkfibre", which might be measured with a power meter and/or OTDR, or
if you have a layer-2 service as you worte above.
A layer-2 service means there is some active gear (usually from your
service provider) in between you and the physical fibre between the
datacenters which they manage and therefore you can not optically
measure the line as a whole.

As a simple test: see if you see have no light (down/down) at both ends
of your connection. My guess: it's only at one end and you most probably
deal with a defective optic (GBIC/SFP) at some point...
Bottom line: most probably you will have to deal with your service
provider.
Good luck.
