FTTH considered very complicated even by advanced countries. It just lag behind a lot, because it needs huge infrastructure to keep it up.
1)It cannot be repaired fast by untrained technician like copper. It needs training and expensive fiber splicers, reflectometer, soldering station (i forgot english name) and etc.
2)Fiber is weak, when it is coming to customer apartment. If there is no proper cable trays and place to put it - it will be often broken. Also rats and mices (and i see a lot of them on the streets) love fiber.
3)It needs MUCH more expensive equipment from ISP side till customer side.
FTTB - yes, it is something, but also too expensive. Usually fiber optics kept only for connecting ISP's, and some internal backbones.
IMHO it is all money laundry. As i heard it is going to be done for Hamra only, and money spent there will be enough to give proper internet for all country. But it is rumours only... truth noone know.
