2. It refers to broadband service provided via light-transmitting fiber-oprtics cables.
Explanation:
FTTH (which stands for Fiber-To-The-Home) is actually only one of the many similar services available, which all are identified by the acronym FTTx, where X, can be one of the following:
H = Home
C= Curb
B = Building
N= Neighborhood
This type of services are given on an all-passive network, composed only by fiber optic cables and passive splitters, carrying the broadband signal over one single fiber directly to the user, employing wave division multiplexing over a single mode fiber, in the 1310/1550/1625 nm range.
