We got a random LOS at 3 AM in the morning. We thought that was a little weird since it doesn't go off when the ISP performs maintenance or is down in the area, however we still believed that that was the case. Several hours go by and still no internet, I ask people I know in the area that is subscribed to the same ISP and they said they still have internet, so it must be a problem with us. We didn't have issues with payment which can only mean it's a technical problem, we requested a technical visit.
However, while I was waiting for the technical visit coming in the next day or two, I followed the optic fiber cable connected to our modem and saw this (this is outside our house btw), that doesn't seem like it's supposed to be like that lol. I closed the box (labeled "FTTH" if that helps) since it was gonna rain and said "f that I'm not messing with optic fiber!"
Here are some supplementary information that may or may not help:
The (white) optic fiber connector connected to the modem is labeled "SC-P", searched it up and I think it's a subscriber connector. The (black) optic fiber connector going from the ISP to us has no label however, but seems very similar in terms of how the port looks.
I also live in a 3rd world country, in a city that's known for crime because squatters in our capital were relocated here, in a neighborhood that is layed out in a way where houses are adjacent to each other, our front door connects straight into a street a few feet wide, and that street connects to a normal street. These facts lead me to think that someone stole a component to sell it for money.
p.s. I just wanted to know what happened, and how we can avoid this problem from ever showing up again.
You need a SC-APC Coupler F/F. Don't worry OP all fiber is colour coded just get one that's light green with that name and you should be fine. The connector could be dirty or damaged which might cause a minor signal loss or even them being unusable. Your ISP should be able to splice a new end or just clean the current one for you.
