Modem (ONU)
CAPEX
EPON: N users (ONUs) require only N+1 optical interfaces
P2P: N users require 2N optical interfaces
for P2P each interface must only carry the user data rate
(e.g. 100 Mbps)
for EPON each interface must carry the full media data rate
(i.e. 1 Gbps)
-> cost for EPON interface significantly higher
