2. HA7200 ONU

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.

HA7200 ONU is cost effective customer device with a 100Mbps ethernet interface,  special designed for FTTH (Fiber to the House) and FTTB (Fiber to the Building). It supplies 1G bandwidth to business users and residential users.
