Help identifying this fiber optic connector?

We have a fiber service coming in, which then goes to a Huawei switch (S5300-10P-LI-AC0), and from there to the router.

I believe they're just using the Huawei switch as a media converter - there is a single fiber optic coming in to an SFP, then a single copper Ethernet cable that runs from there to the router.

I'm trying to identify the type of fiber connector this is?

Does anybody know?

Secondly - the fiber comes in via a hole in the wall, and goes to this box:

We need to move the box to a different location - is there a safe way to disconnect the cable from the box, and reattach it afterwards?
