GPON SYSTEM, Basic Concepts

What is GPON?

GPON stands for Gigabit Passive Optical Networks. Technically, GPON is a point-to-multi point access mechanism. Its prime characteristic is to use passive splitters in the fiber distribution network, enabling a single feeding fiber from the Internet Service provider’s central office to serve multiple users at homes and small businesses.

What is Passive optic network?

A passive optical network (PON) is a fiber Optical network which uses a point to multipoint networking technique and optical splitters for delivering data from a single main data source to multiple endpoints.

Although, there are many subtle differences, a distinction between active optical network and PON topology is PON’s use of a technique that distributes a single signal to multiple endpoints through unpowered devices called optical beam splitters.

What are the benefits of PON?

PON was developed in the mid of 1990s. It was originally designed to allow Internet Service Providers (ISPs) to deliver Triple-play broadband services (data, voice, and video) to residential users.

However, Its main purpose was to reduce the number of fiber cable run required to reach multiple end-user points and to eliminate the requirement need to provide power to transmission devices between the central office and the end user. Consequently, Due to these both issues had hindered deployment of FTTP (fiber to the premises) or FTTH (Fiber to the Home) services at that time.

Furthermore, Its focus was on fiber connectivity to the home, other types of network users–such as hotels, hospitals, and high-rise residential buildings are now looking for same advantages to improve fiber efficiency by developing this technology.

What is AON? And why we don’t use it frequently?

What is FTTH?

Fiber to the Home

What is ONU or ONT?

On a fiber network, the ONU/ONT is located at your home. However, The purpose of this device is to use optical fiber to connect to the passive optical network (PON) and communicate with your Internet service provider to get an Internet connection.

The ONU usually communicates with an ONT, which may be a separate box that connects the PON to TV sets, telephones, computers, or a wireless router.

How does ONU works?

An ONU is located outside the home. An ONU converts optical signals to electrical signals via a fiber cable. An ONU organizes and optimizes different types of data coming from customers to efficiently send it upstream to the OLT (located at an ISP’s central hub).

What is OS2 fiber? And what are other types of fiber cables?

OS2 fiber optic cable is a cable which is designed for larger transmission ranges having distance of 5,000 to 10,000 meters with similar transmission speed of 1 to 10 gigabit Ethernet.

What are Telecommunication Standards?

IEEE and ITU-T
