Single-mode cable to multi-mode interface

fiberlayer1

I have a 1500' fiber run to make for data 10/100. The interface on each end is multi-mode, but the cable I have is single mode. Can this be done? I'm new to fiber so be gentle with me.

The scenario you are asking about will not work.

The answer is in the name - "multimode" fibre carries multiple modes of light. "Singlemode" fibre carries only a single mode. So you can not carry multiple modes of light down a fibre that only supports a mode.

You can use multimode fibre to connect singlemode interfaces but this will only work over a short distance. Soon you will encounter some sort of dispertion so its not really recommend but it will work as a last resort.
