What is GPON ONU(ONT) and GPON OLT?

GPON (Gigabit Passive Optical Networks) stands for the latest standard of PON access broadband based on ITU-TG.984x, which can provide high broadband, highly efficient service, wide-range signal coverage, abundant access ports. It is considered as the ideal technology to achieve different demands for access networks by the operators. Accordingly, There are GPON ONU and GPON OLT. What are GPON ONU and GPON OLT exactly? Just read the below to get more info.

 

1. What is GPON ONU(ONT)?


The GPON ONU (optical network unit) or ONT (Optical Network Terminal) is usually located at customers premises. It's also described as CPE units. There is a little bit of difference between ONU and ONT but we generally consider them as one thing. Moreover, there are different configurations for the ONU/ONT devices. Some have Gigabit Ethernet or Fast Ethernet ports, others may support analog phone or wireless Internet.

Example:
V2804RGT: V-SOL 1GE+3FE+CATV GPON ONU
This device has 1 Gigabit Ethernet port, 3 Fast Ethernet ports and 1 CATV port. It's Fully compliant with IEEE 802.3ah specifications. It supports NAT, Firewall, VLAN, DHCP Server, and IGMP snooping multicast.


 

2. What is GPON OLT?


The GPON OLT connects the ODN. There are two transferring directions of OLT. One is upstream, which is used to distribute different types of data and audio traffic from users. The other one is downstream, which acquires data, audio and video traffic from MAN and toll network.

Example:
V1600G1-B: V-SOL 8 Port GPON OLT
There are 8 GPON ports, 2 GE (SFP+) ports, 2 10G (SFP+) ports, and 4 GE (RJ45) ports. It's fit for sparse or remote areas, smart industrial parks, commercial buildings and FTTM.
