PON standards is GPON

 

 

Fiber optic networks operate according to various standards for Passive Optical Networks (PON). PON is a network system designed specifically for fiber optic technology to provide broadband network access to homes and businesses. One of the many PON standards is GPON.

GPON stands for Gigabit Ethernet Passive Optical Network (PON). GPON uses Asynchronous Transfer Mode (ATM) for voice, Ethernet for data, and a proprietary encapsulation for voice. This means that fixed-size cells are used instead of variable-size data packets. It offers faster Gbit/s in downstream and upstream bandwidth than EPON (Ethernet Passive Optical Network).

GPON system consists of an Optical Line Terminal (OLT) that connects multiple Optical Network Terminals (ONT/ONU) over a Passive Optical Distribution Network (ODN).

 

GPON supports:

• Triple-play services (VoIP, data, IPTV) and offers competitive all-service solutions.

• Higher data rates and bandwidth

• Longer distances

• Improved security and data encryption (supports 128-bit block length and 128, 192, and 256-bit key lengths)

• All types of Ethernet protocols

 

GPON offers:

• Superior Quality of Service (QoS)

• Dynamic bandwidth allocation capabilities

• Flexibility

It is a popular option among major telecommunications operators worldwide. GPON also allows the consolidation of multiple services onto a single fiber optic transport network, which is why many choose GPON over other technologies.

 

GPON Basics and How It Works:

GPON is a point-to-multipoint access network. The main feature of GPON is the use of passive splitters in the optical fiber distribution network (ODN), which allows a single fiber optic cable from an Internet service provider (ISP) to serve multiple homes and businesses. Fiber optics means that fiber optic technology uses cables to transmit light.

In this example, the GPON system starts at the Optical Line Terminal (OLT) at the Internet Service Provider's (ISP) headquarters.

1. The Internet, voice/telephone, and TV data services provided by the ISP originate from here.

2. This data travels through a single Optical Fiber Distribution Network (ODN) until it reaches a passive optical splitter.

3. When the data reaches the splitter, the optical signal is split into multiple signals and distributed to individual ONT/ONU devices in your home or business, providing access to these services. The ONT/ONUs are the endpoints.
