There are two broad choices
for FTTH networking, based on the choice of topology and technology:
Active Ethernet (AON) over point-to-point (p2p) networks and Passive
Optical Networking (PON) over p2p or point-to-multipoint networks.There is no consensus on
which option is best, and even attributing cost advantages to PON, and
bandwidth advantages to AON, is disputed . All in all, AON has a
number of advantages, whereas the cost aspect of PON over p2mp could be
somewhat more attractive. When the total cost of ownership, including
the real option value associated with upgrading and the possibilities of
switching technologies, is taken into account, a p2p network is more
apt for reducing technology risks.
