That is, to FTTB Fiber The Building (fiber-optic to the floor) and it is to use digital broadband technology, fiber optics, and then directly to the small area through twisted-pair (super-category 5 twisted-pair or 4 for non-shielded twisted pair) to individual user.

FTTB, namely Fiber to The Building (optical fiber to building), it is uses the digital wide band technology, the optical fiber directly to the plot in, again through twisted pair line (ultra five kind of twisted pair lines or 4 pair of non-shielded twisted pairs) to each user.

FTTB, Fiber to The Building (fiber to the building), it is the use of digital broadband technology, optical fiber directly to the community, again through twisted-pair cable (CAT twisted or 4 pairs of unshielded twisted-pair cable) to the individual user.
