What is GPON Internet?

GPON Internet is an optical data transmission technology that allows you to connect subscribers to the Internet with high speed and reliability. In this article we will tell you what GPON Internet is, how it works, what advantages it has and how to connect it.

What is GPON Internet?

GPON (Gigabit Passive Optical Network) is a passive optical network that uses optical fibers to transmit data between the central office (OLT) and subscriber equipment (ONT). GPON Internet refers to the ITU-T G.984 standard, which defines the parameters and characteristics of such a network.

GPON internet provides high data transfer speeds - up to 2,5 Gbit/s in the direction from OLT to ONT and up to 1,25 Gbit/s in the opposite direction. In addition, GPON Internet supports various types of traffic, such as Internet, telephony, television, video surveillance and others.

How does GPON Internet work?

GPON Internet operates on the principle of time division (TDM) and wavelength division (WDM). TDM means that data from different subscribers is transmitted over the same optical fiber at different times, and WDM means that data from different types of traffic is transmitted over different wavelengths.

GPON Internet consists of three main elements:

• OLT (Optical Line Terminal) is a central device that connects to the Internet provider and manages data transfer between optical fibers and subscriber devices.
• ONT (Optical Network Terminal) is a subscriber device that connects to an optical fiber and converts optical signals into electrical signals, and also provides connectors for connecting various devices such as a computer, telephone, TV and others.
• ODN (Optical Distribution Network) is an optical fiber network that connects OLT and ONT. An ODN may include various passive optical components such as splitters, connectors, adapters, and others.

Schematically, GPON Internet can be represented as follows:

Advantages of GPON

Connecting to the Internet via GPON has several advantages over other technologies such as ADSL, VDSL, Ethernet or DOCSIS. Here are some of them:

• High speed. GPON allows you to get Internet speeds of up to 2,5 Gbit/s, which is several times higher than the speed of other technologies. This means you can watch high-definition videos, play online games, download large files and use other Internet resources without lag or interruption.
• Reliability. GPON uses optical cable that is not subject to electromagnetic interference, corrosion, overheating or mechanical damage. In addition, a passive optical network does not have active elements that can fail or require replacement. This ensures stability and quality of communication in any conditions.
• Economical. GPON allows you to reduce the cost of connecting and maintaining the network, as it does not require additional equipment, electricity or personnel. In addition, GPON allows you to receive several communication services over one cable, which reduces the number of wires and sockets in the apartment.
• Versatility. GPON supports various protocols and data transmission standards, such as IP, ATM, Ethernet, TDM and others. This allows you to connect any devices to the network and use any communication services, such as the Internet, television, telephony, video surveillance, intercom and others.

Disadvantages of GPON

• Limited bandwidth. Although GPON provides high Internet speed, it is not guaranteed, but depends on the number of subscribers connected to one optical splitter. If there are many subscribers, the network bandwidth will be divided between them and the Internet speed may decrease. Therefore, it is important to choose a provider that controls the number of subscribers per divider and provides sufficient bandwidth for each subscriber.
• Low security. GPON uses one optical cable to transmit data from the provider to subscribers connected to the same splitter. This means that all subscribers receive the same signal, which can be intercepted or modified by attackers. Therefore, it is important to choose a provider that uses various encryption and authentication methods to protect your data from unauthorized access.
• High price. GPON requires the installation of special equipment, which is quite expensive. This applies to both OLT located at the provider and ONT located in the subscriber’s apartment. Moreover, the cost of optical cable is also higher than the cost of copper cable. Therefore, tariffs for connecting to GPON may be higher than for connecting to other technologies.

How to connect GPON Internet?

In order to connect GPON Internet, you need to complete the following steps:

• Contact an Internet provider that provides GPON Internet service in your region and sign a connection agreement. (For example Briz)
• Choose a plan that suits your needs and budget. Typically, tariffs depend on the speed, volume and type of traffic, as well as the availability of additional services such as telephony, television and others.
• Receive an ONT subscriber device from your Internet provider, which must be connected to the optical fiber that the provider will extend to your home or apartment. An ONT can be internal or external, depending on the type of optical fiber and installation location.
• Connect to ONT various devices that you want to use to access the Internet, such as a computer, phone, TV and others. To do this, you will need Ethernet cables, telephone lines, coaxial cables, or wireless connections.
• Configure settings

 

 

Conclusion

GPON is a modern Internet connection technology that provides high speed, reliability, efficiency and universality of communication. It allows you to receive Internet, television and telephony via one optical cable, which is laid directly into the subscriber’s apartment. In order to connect to GPON, you need to select a suitable provider, order a connection, wait for the ONT to be installed and connect your devices. However, GPON also has some disadvantages such as limited bandwidth, low security and high cost. Therefore, you can consider other alternatives such as Ethernet, DOCSIS or Wi-Fi, which also provide fast and high-quality internet.
