Hey there MambaFiber,
Thanks for shedding some light on the possibility of using these cables.
The cables are duplex terminated with FC connectors so I'd have to use a jumper cable to complete the termination.
It's an alternative that we're considering as they're used by the country's telco, and it's about 25cents/meter.
The trouble with these cables though are they're really, really tough to roll up again.

If it has some other connector type, you can use adapters or short jumpers with differing ends to make your connection happen. If it's bare fiber ends, then you will have to have connectors put on. I suggest fusion splice connectors-and a professional to install them.
The only material pertaining to fiber type for BMD gear you need to know is this...
Singlemode Fiber (9 um core, 125 um cladding)
LC/UPC connector
This is what the SFP modules that BMD ship are designed to work with. That's not to say that multimode fiber WON'T work, you may be lucky and have good performance. However it's not what was designed or intended to work. Any connector other than LC will not fit in the socket, and will have to be adapted.
You would usually choose duplex cable, meaning it has 2 fiber cores. You can also use simplex (1 fiber core) cable and run 2 if you need both connections. There are also cables with more cores, like 6 or 12 and just connect the ones you need, or use multiple devices without having to run separate cables.
Replacing the SFP modules with a MM variant, or a WDM variant (single fiber instead of 2) is definitely possible. If you must use cabling other than intended I would recommend this. I'd look to a vendor such as Thor Fiber, or FS.com, or Fiber Instrument Sales. These guys can hook you up with different parts to accommodate other scenarios than what BMD originally intended. We use parts from all of these vendors with great success, but we do not use MM cable at all as we usually need greater distance than MM can offer (usually around 1500ft max).
