Question : Problem: Type of fiber port is this refer to picture?

Hi

What Type of fiber port is this refer to picture?

People on exchange expert told me its a FC port so I bought a 1 meter FC to ST Single mode Duplex Patch Cable because my fiber converter has ST ports but FC side of fiber cable is not fitting on FC port so
Is it a FC port on picture or is a fitting missing please explain.

Take a look at the cable connector ends in the link I posted. You'll find a picture of the FC also. Then you can look at what you have and maybe make a more informed judgement call.
