The first thing you need to do is test the fiber with an OTDR. If you
don't have one, you can probably contract a local cabling company to test
it for you.
Why would you want an OTDR report on

Pardon my ignorance in this area but is too much to ask for OTDR data before

wanted to do xWDM in the future.
Yes, it's too much to ask. They won't splice your path
