GEPON ONU has 1 SC/PC PON port and 8*10/100BASE-T ports, pure data type. The 8 port MDU GEPON ONU is a passive optical networking CPE, based on the broadband access of EPON technology, giving an integrated solution of the broadband access to the user based on the EPON technology. The Pure Data Type FTTB GEPON ONU provides symmetrical 1Gbps uplink and downlink transmission rates and communicates with the head-end device (BD-OLT-2000 OLT). The 8FE ONU guarantees consistent QOS and flexible bandwidth allocation for Ethernet and IP integrated services to the consumer. The 8 port ONU complies fully with IEEE technology standards, addressing the EPON device technology criteria of domestic multiple operators.

EPON Technology is a rising technology that combines with PON and Ethernet Technological superiority. It is a technology that point to multi-point networking. Through the Passive Optical Networking, the OLT device gather together with many ONU devices for interconnection, and it is combined with the technology of SFP BIDI, so EPON system could use less fiber resources to meet the needs of Operator about the multiuser for multiple service access.
