Must say standard SMF bothers me, I wish I'd bought one with an outer sheath around the two inner ones, so it looks more like a normal cable, as I kinda worry its too flexible and exposed to being damaged. Granted, the fibre itself is insanely thin inside those sheaths. I'd like a cable I can't physically bend too tightly as I'm scared to cable manage the fibre.
Still, no point replacing it now just in case it gets damaged, as that defeats the point really. IF it gets damaged I should then get something more robust.
I was able to yank it through the hole my other cables come through without issue, that sheathing is so slippery its the easiest cable run I've ever done.
