Introduction:

Are you tired of low internet speed? Do you want to take your internet speed to the next level? GPON is undoubtedly a solution to this problem. In this era where technology is ruling, many people want a rapid solution to their network-related problems. As a result,  high-speed internet appears as a necessity rather than a luxury. This is where GPON comes into play.  It transfers the data in a way that is as reliable and flexible as possible. However, it is different from the traditional fiber optic cable but much faster and more efficient than the traditional cable, making the broadband speed faster. If you are interested in going deep, this blog is meant for you.

What Is GPON?

What Is GPON

GPON stands for the Gigabit Passive Optical Network consisting of optic fiber technology that transfers data faster. GPON network transfers the data from the fiber optic cable for faster broadband. From offices to homes, it’s the choice of many. It transfers the data through the fixed Gbps via fiber optic cable. The use of Gigabit Passive Optical Network relies on users who want faster internet connectivity and like videos, voice, and data.

Working of GPON:

GPON is a network that provides the data transfer from one to multiple points which makes the work efficient.  In this way, the service provider of the internet provides the data from the residencies to the offices and the enterprises. The signals are sent through the Optical Line Terminal (OLT) to the Optical line Unit (Olu). These are one of the networks that provide fast and easy data transfer through one cable. In Addition,  OLT usually supports up to 72 ports and Onu connects to the end which gives signals back to the OLT. The GPON speed reaches up to 2.488 Gigabits per second on the downstream and to the upstream it speed can reach up to 1.244 Gigabits. If you are thinking ‘How does GPON work? Just look at the following chunks:

  1. It transfers the data through a single Fiber optic cable to multiple devices rather than multiple cables.
  2. Optical Line Terminal (OLT) sends data to the upstream for the users and then receives the downstream data addressed to it.
  3. And for the OLT the fiber optic turns the optical signals from the optic cable to the electrical signals.
  4. The data that have been transferred to the ONT and ONU is then sent to the OLT by using the TDMA (Time Division Multiple Access) which then transfers data without any disruption or collision.
  5. The data transmission speed in GPON protocol is 2.5 Gbps in Downstream and 1.5Gbps in upstream network.

Features of GPON:

Below are some of the key features of the GPON:

Increased Bandwidth: It supports services like HD video streaming, Data applications, and online gaming. Its downstream speed is 2.5 Gbps, while its upstream speed is 1.25 Gbps. 

Distance Coverage: GPON can cover a distance of up to 20 km transferring the data to OLT (Optical Line Terminal) and OLU (Optical Line Unit) without any collision of data, and the performance is not affected by that it can be used in both enterprises and residencies.

Scalability: GPON can be easily scalable to the number of other devices and the subscribers of the devices, and it can be increased with the number of splitters among the devices. 

Security: It transfers secure communication among the users and also uses encryption.

Ease of Installation: It’s quite easy to install as it does not require any heavy maintenance to keep it working.

Triple Play services: GPON can deliver IPTV, VoIP, and other data services with high-speed data with the same network

What is GPON OLT and GPON ONT:

GPON comprises two devices, which are the Optical Line Terminal (OLT) and Optical Network Terminal (ONT):

GPON OLT:

The GPON is located in office buildings and enterprises; as we talk about the OLT and OLU, there are a few differences between them. As we talk about the GPON OLT, it connects its network to the ODN (Optical Distribution Network). The OLT can transfer the data in two different directions: one is upstream while the other one is downstream. The upstream ones distribute the different types of data and the traffic to the different users. Downstream obtains the data, audio, and video traffic to the toll network. The OLT has network management. It can manage all the PON Networks, which includes all the monitoring and maintenance. As discussed before, can optical signals be converted into electrical signals? Which helps the user to get fast and reliable data. They also support the various services and interfaces.

GPON ONT:

It also comes with a CPE unit. They also support the various services and interfaces. Some of these may include Fast Ethernet and Gigabit Ethernet ports. Its delivery speed is faster, i.e., Fast Internet. Signals received from the optical cable turn the optical signals into electrical signals that are used by the users, such as TVs, phones, and computers. Also, GPON ONT gives a high-quality experience to the Users who use GPON ONT.

Conclusion:

In this Guide, we discussed the GPON and its connection with the other PON networks. Apart from that, the Gigabit Passive Optical Network (GPON) is an absolute technology in the way we think or work through it and make things simpler for users. It comes with high data speed, different architectures, and the way they look. In this challenging technology war, faster Internet is everyone’s choice, and GPON is the solution for every Technology freak looking for the best Internet Service Provider. This guide will surely clear your every query regarding GPON and explain how it’s the perfect solution for high-speed Internet.

Frequently Asked Question:

Is GPON better than Fiber?

GPON fiber optic cable separates the data, voice and video onto a single Network Layer. A GPON can provide a high level of service quality for each type of communication.

Is GPON still used?

GPON is most used around the service providers among the users. It’s the most complex, reliable, cost-effective and most easy to install fiber optic technology.

What does GPON mean?

GPON is a Gigabit Passive Optical Network; it is used for high-speed internet in telecommunication for High gigabit speed among devices.

What is the difference between GPON and FTTH?

GPON is the optical fiber that is used to bring technology that uses optical fiber to transmit data and it is mostly used for long Distances. The FTTH refers to the physical infrastructure and it brings the fiber optic cables directly to the home.
