ONT encyclopedia

What is ONT?

ONT (Optical Network Terminal) is an optical network terminal, commonly known as an optical cat. It is a device that provides home users with access to the network. It can provide high-speed Internet access, IPTV, voice, and WiFi services.

Difference between ONT and ONU

ONT can be understood as ONU (Optical Network Unit), but in the strict sense belongs to ONU.

The difference between the two is that the ONT is an optical network terminal and is located directly at the user’s end; the ONU is an optical network unit, and there may be other networks between the user and the user, such as a gateway device under the ONU that can access xDSL or Ethernet access ports, and then Connect to a network terminal.

ONT position in the network

ONT is usually located in the user’s home, accessing various Internet access devices downwards, and accessing the network through optical fibers.

Huawei ONT Product Classification

Huawei’s common ONTs are roughly divided into traditional ONTs, intelligent ONTs, converged gateway ONTs, and 10G PON ONTs according to their functions. Among them, traditional ONTs can be divided into bridged ONTs and gateway ONTs according to their functions.

Bridged ONT

The bridge-type ONT is only responsible for transparent transmission, providing users with Internet access and IPTV channels, and can only connect to the network after dialing on user equipment such as a router or PC. Some bridged ONTs also support voice functions and can be connected to telephones.

If a bridged ONT is connected to a wireless router downstream, it can access the Internet wirelessly.

Representative products:
EchoLife HG8010H: Support 1 GE;
EchoLife HG8240H: Support 4 GE + 2 POTS

Gateway ONT

Gateway ONT Compared with bridged ONT, it can realize routing and forwarding to automatically assign IP addresses, and users can connect to the network without dialing by themselves. Some gateway-based ONTs also come with dual-band WiFi (2.4G Hz & 5G Hz), which can provide wireless networks.

Representative products:
EchoLife HG8540M: Support 1 GE + 3 FE;
EchoLife HG8247H: Support 4 GE + 2 POTS + CATV + USB + Wi-Fi

Intelligent ONT

The biggest difference between a smart ONT and a traditional ONT is that it can be used in conjunction with sensors (door sensors/smoke/water flooding / infrared alarms, etc.) to provide new functions such as real-time video monitoring, intelligent speedup, home control, etc., combining cloud platforms and intelligence Home APP can also realize remote control of the smart home.

Representative products:
EchoLife HS8145V5: Support 1 phone + 3 Gigabit + 1 iTV + 1 USB + 2.4G & 5G Wi-Fi;
EchoLife HS8545M5: Support 1 phone + 1 Gigabit + 3 100M + 1 USB + 2.4G Wi-Fi

Converged Gateway

The converged gateway mainly integrates the STB function (iTV) on the gateway ONT, reduces the number of boxes, simplifies the installation, and supports 4K video. It is mainly used in hotel scenarios and a one-stop solution for Wi-Fi coverage and video experience.

Representative products:
EchoLife HS8125T: Support 1 GE + 1 FE + 1 POTS + 2 USB + 2.4G Wi-Fi + 1 HDMI interface + 1 Mini AV + 1 infrared receiver + infrared extension buckle + 1 Micro SD card slot;
ChoEchoLife LS8025T: Support 2 FE + 2.4G Wi-Fi + 1 HDMI interface + 1 Mini AV + 1 infrared receiver + infrared extension port

10G PON ONT

10G PON ONT’s user-side speed can reach Gigabit, which can not only meet the high-bandwidth services such as 4K / 8K high-definition video, AR / VR, home cloud, video calls for home users but also provide up to 10 Gigabit dedicated line access services.

Representative products:
EchoLife HN8245Q: Support 4 GE + 2 POTS + 2 USB + 2.4G & 5G Wi-Fi
EchoLife HN8546Q: Support 4 GE + 1 POTS + 2 USB + 2.4G & 5G Wi-Fi
