I have this connector on my optic fibers cable and I want to remove the connector so I can pass through a hole in the wall I have no tools for optic fiber cables and i cannot make the whole any larger, can I remove the connector from the cable and put it back on ?
You need special equipment as everyone said.
They need to cut the fiber and then polish it to a near perfect microscopic finish, so it has the best optical quality. You can’t do that without expensive equipment and knowledge.
