| Passive Optical Components |
In Passive Optical Components, the following components are used:
The equipment at your ISP's central hub is called an optical line terminal (OLT).
The optical network terminal (ONT) is a device that is located near your house or office.
Optical network unit (ONU), which is nearly identical to an optical network terminal (ONT).
Passive Optical Components is an acronym for passive optical network.
From an Internet service provider (ISP) to the end-user, a PON system transports optical fiber cabling and signals all or most of the way.
A PON system connects you as a subscriber to your ISP and provides broadband Internet access to your home or office.
The system will be classified as fiber-to-the-curb (FTTC), fiber-to-the-building (FTTB), or fiber-to-the-home (FTTH) depending on where the PON finishes (FTTH).
PON's Components
In a passive optical network, the following components are used:
Optical line terminal (OLT), which is located at your ISP's central hub; Optical network terminal (ONT), which is located near your home or office; Optical network unit (ONU), which is nearly identical to an ONT.
The way these components are connected has an impact on how the PON works.
The Passive Optical Components uses less fiber than a point-to-point system (also known as an active optical network, or AON).
What is a PON and how does it work?
The architecture of a PON is point-to-multipoint, which means that unpowered fiber optic splitters serve numerous endpoints over a single optical fiber line.
It's a passive optical network due to the unpowered splitters.
PON takes its name from this.
Passive optical networks come in a variety of shapes and sizes (PON)
There are several sorts of PONs and words to be aware of:
Asynchronous transfer mode (ATM) passive optical networks are referred to as APONs.
The first PON standard was APON, which was designed for corporate applications.
APON employed fixed-sized cells instead of the variable packet sizes used by Ethernet and the Internet.
Broadband passive optical network (BPON) is an acronym for broadband passive optical network.
BPON was similar to APON, but it added capability for wavelength division multiplexing (WDM), which allows numerous ISPs to transmit at various wavelengths on the same single fiber.
Ethernet passive optical network (EPON) is an acronym for Ethernet passive optical network.
Instead of ATM cells, EPON uses Ethernet packets.
EPON also sends data, phone, and video over the Internet Protocol (IP).
It typically provides 1G symmetrical bandwidth, making it a popular option.
The GPON (Gigabit Ethernet Passive Optical Network) acronym stands for Gigabit Ethernet Passive Optical Network.
GPON employs proprietary encapsulation for voice, Ethernet for data, and ATM for voice.
