5.1 HA7208 ONU installation
ONU (Optical Network Unit) is the user equipment of EPON.
It can end the operation from OLT (Optical Line Terminal) by PON and provide all kinds of broadband services cooperated with OLT.
ONU is configured and managed remotely by OLT.
HA7208 ONU is cost effective customer device with four 100Mbps ethernet interfaces,special designed for
FTTH (Fiber to the House) and FTTB (Fiber to the Building).
It supplies 1G bandwidth to business users and residential users.
