Connecting two switches together using single mode fibre and SFP’s

One of my clients require two of their Meraki MS120 switches to be connected together. They are in separate server rooms, around 1000 meters away from each other. Obviously Cat5/6 isn’t an option here, but there is a single mode fibre tie between the two locations.

I don’t normally work with fibre, but I was told by a friend/colleague that connecting switches together requires the use of multi mode fibre, and single mode fibre will not work (something to do with the core diameter).

Is this true? I have a feeling this guy is yanking my chain.
