What is an ONT?
ONT stands for Optical Network Terminal. This device is an output on the internet and is specific to fiber optic technology, just like a cable modem, it is the output of the internet connection with a coaxial cable. A device that communicates directly with an Internet Service Provider (ISP) to provide a fiber optic Internet connection to your home or office. However, the ONT fiber optic modem is for fiber optic internet, so you cannot use the ONT with Ethernet over coax or a MoCA device such as a cable modem, router or cable modem router.
ONT buying guide
To buy a suitable ONT device, the first and most important thing to do is; Do your research and find the right fiber optic modem brand. For example, in the telecommunication center where the OLTs are from the Huawei brand, we cannot buy ONTs from the Zycell brand.
The second thing to pay attention to when buying an ONT device is the Wi-Fi antenna. According to this issue, you should get the modem with internal or external antenna.
The last thing to pay attention to is the type of ONT. You can buy single port, 2 port or 4 port ONTs. The price of ONT is very different according to the number of telephone outputs.
Difference between ONT and ONU fiber optic modem
To better understand the difference between ONT and ONU, it is better to take a look at the general definitions of these two.
ONU optical network unit
ONU converts optical signals sent through fiber into electrical signals. These electrical signals are then sent to individual subscribers. Generally, there is another distance or access network between the ONU and the end-user location. In addition, the ONU can transmit, collect and modify various types of data received from the client and send them upstream to the OLT.
The OLT supports bandwidth allocation, which allows data to be delivered to the OLT in a floating manner, which usually arrives from the customer in bursts. The ONU can be connected by various methods and types of cables, such as twisted pair copper wire, coaxial cable, optical fiber. or Wi-Fi connected.
ONT optical network terminal
ONU and ONT are basically the same device. ONT is a term from ITU-T standard, while ONU is a term from IEEE standard. The ONT is located at the customer's premises and the ONU is located outside the home. The ONU usually communicates with an optical network terminal ONT, which may be a separate box that connects the PON to a TV, phone, computer, or a wireless router.
