I had AT&T Fiber installed today. The technician had to create a hole on the side of my garage for the fiber optics cable. As you can see, it doesn't look pretty. But I'm not really concerned with aesthetics since it's not visible from the road. I'm worried about water going in. There's no drip loop, so I can see the water just following down the cable. Any tips on what kind of products I can use to clean this up and waterproof? Thanks!
Wow, he didn't really care much about craftsmanship. No drip loop sucks; see if there is any slack where you could pull it down a bit into a gentle loop and use a zip-tie to hold the shape (don't kink it). Really all I can see you doing is globbing silicone sealant around it; use the paintable type and maybe you could make it look a bit better by painting the glob once it has cured.
They make split wall bushings you could use to dress it but you would still need the glob of silicone to prevent water intrusion.
