I have two places to connect. Let's call it, place A and place B.
On place A there is a Fortigate100D which has this kind of port;
On place B there is a Cisco SF200-48 10/100 Smart Switch;
I have made the 1km cabling with this cable;
I think the cable is Single-Mode and the termination should be with SC. I also probably need an SFP device, but as I searched, I should use 1000BASE-LX for single mode fiber. The question is I didn't see any SFP device with 1 SC connection. I am perplexed right now and need some help.

The yellow cable indicates single-mode fiber which is also necessary for a reach of more than a few hundred meters. The usual Gigabit Ethernet PHY for this is 1000BASE-LX, you're correct. (It's actually 1000BASE-LX10 for 10 km reach, the original 1000BASE-LX with 5 km reach is pretty much obsolete. You could also use 1000BASE-BX10 with single strands.) From the photo, the fiber is unterminated.
SFP modules use LC connectors as SC is too large to fit. Many fiber panels terminate with SC jacks, so you use SC-to-LC patch cables. Make sure you get single-mode patch cables as well.
When buying transceivers, watch out for their brand compatibility - most devices only accept correctly branded transceivers: in your case Fortinet on the one and Cisco on the other side. The transceivers don't necessarily need to be original vendor's, there's a large market of compatible modules.
On the FGT-100D, note the shared TP/SFP ports - port 15 is already in use with twisted pair, so you'll need to use port 16.
