What Does ONT Mean?


1. What is ONT?

The meaning of ONT is an optical network terminal, which is a device providing the family with access network. ONT is a separation between the Ethernet network and customer premises.

It can transfer optical signals from OLT (optical line terminal) into electric signals and offer various services such as high-speed Internet, IPTV, VOIP, WiFi, etc. to users.

Besides, sometimes people consider ONT as ONU (optical network unit). But technically, there is still some difference between ONT and ONU. ONT is a terminal device that is located at the user’s end. ONU is a unit and there are probably other networks between ONU and Users.

2. VSOL Related ONT Devices

According to different features, VSOL divided its ONT routers into several types like CATV ONT, POE ONT, AC ONT, etc. Here we list 2 representatives to help you learn more about ONT devices.


The XPON HGU supports dual modes including GPON and EPON. It’s compliant with IEEE802.11b/g/n/ac and dual bands (2.4GHz and 5GHz). It can provide Triple-play services including Internet, CATV, and VoIP. With one ONT router, you can enjoy a smooth network with easy installation. Moreover, the device supports EasyMesh with easy pairing in your house.

● V2808PD: 8FE Reverse PoE ONU

The Reverse POE ONT has 1 GPON uplink port and 8 LAN user ports. It’s designed for the application in places where there is no alternating current (AC) power supply. The ONT is waterproof and lightning-protection so it can be installed outdoor. The reverse POE ONT mainly makes difference in solving the difficulty of accessing electricity in corridors and outdoor. In the FTTH application, the users are responsible for the payment for the electricity so the costs of ISP will be reduced.
