Gigabit Passive Optical Networks
The GPON standard specifies up to 128 splits can be on a single GPON port, but traditional GPON deployments use 1:32 or 1:64 way splits. GPON uses separate wavelengths to transmit and receive traffic (1490nm from OLT to ONT, and 1310nm from ONT to OLT).
A GPON network is capable of transmitting ethernet, TDM (Time Division Multiplexing) as well as ATM traffic. A GPON network consists of OLT (Optical Line Terminals), ONU (Optical Network Unit), and a splitter. GPON utilizes both upstream and downstream data by means of Optical Wavelength Division Multiplexing (WDM).
GPON is a point-to-multipoint access network. Its main characteristic is the use of passive splitters in the fiber distribution network, enabling one single feeding fiber from the provider to serve multiple homes and small businesses.
A single fiber can be split into many branches to support multiple end users. The strain on the fiber backbone can be greatly decreased through the application. To sum up, fiber optic splitter provides a solution for improving the efficiency of optical infrastructures.
DSL, Cable, and FTTH all have a dedicated line running to your home. The difference is the type of line. Yes it is shared, but it's not likely to affect gaming. Everything's shared when the internet is involved; you need a dedicated point-to-point link if you want to avoid sharing.
GPON (Gigabit Passive Optical Network) is a point to multipoint technology than connects an Optical Line Terminal (OLT) to many Optical Network Terminals (ONTs), also known as Optical Network Units (ONUs).
Fiber to the home (FTTH), also called "fiber to the premises" (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access.
FTTH - GPON. Advertisements. GPON (Gigabit Passive Optical Networks) is an Optical System for the Access Networks, based on ITU-T specifications G. 984 series. It can provide a 20 km reach with a 28dB optical budget (shown in the following illustration) by using class B+ optics with 1:32 split ratio.
An optical line terminal (OLT) is the endpoint hardware device in a passive optical network (PON). An OLT has two primary functions: Converting the standard signals used by a FiOS service provider to the frequency and framing used by the PON system.

In fact, both GPON and EPON deliver Ethernet to the end user. The difference is GPON is a purpose-built point to multi-point transport protocol while EPON conscripts Ethernet to attempt the same inefficiently.
How GPON Works. A GPON network consists of OLT (Optical Line Terminals), ONU (Optical Network Unit), and a splitter. The splitter will divide the signal when needed. The OLT takes in all of the optical signals in the form of beams of light from ONUs and will convert it to an electrical signal.
All FTTH networks are based on standard SM fiber(ITU G. 652), also called dispersion unshifted or non-dispersion shifted fiber. The only fiber option normally considered is to use low-water vapor fiber that removes the water peak at 1400 nm. A home run architecture uses a direct fiber run from the CO to the customer.
A key benefit to FTTH -- also called FTTP, for "fiber-to-the-premises" broadband -- is that it provides for far faster connection speeds and carrying capacity than twisted pair conductors, DSL or coaxial cable. FTTH will be able to handle even the futuristic Internet uses some experts see coming.
Fibre cables run from the exchange to the cabinet on your street, which then connects to your home via the ol' copper phone line. Fibre-to-the-home (FTTH), meanwhile, means the entire line is fibre from the exchange all the way into your building.
Architecture drives costs in FTTH networks, and there are different types: centralized split versus distributed split, star versus daisy-chain, and all-spliced versus hardened connectivity.

The OLT takes in all of the optical signals in the form of beams of light from ONUs and will convert it to an electrical signal. OLTs normally support up to 72 ports.
Dial-up is NOT a type of broadband Internet connection. The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access.
Fiber to the home (FTTH) is the delivery of a communications signal over optical fiber from the operator's switching equipment all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires and coaxial cable.
Fibre to the Premises runs over a fibre optic cable from the telephone exchange, all the way to inside your property. The fibre from the exchange is normally terminated on the outside wall of a home, and a short fibre lead run inside to the fibre modem, which then offers an Ethernet connection to a broadband router.
GPON stands for Gigabit Passive Optical Networks. GPON is a point-to-multi point access mechanism. Its main characteristic is the use of passive splitters in the fibre distribution network, enabling one single feeding fibre from the provider's central office to serve multiple homes and small businesses.
Typically, a fiber optic cable contains three basic components: the core, which carries the light signals; the cladding, which surrounds the core with a lower refractive index and contains the light; and the coating, which protects the fragile core and cladding within it.
GEPON Definition
GEPON (Ethernet Passive Optical Network) is a new type of optical access network technology that uses point-to-multipoint architecture and passive optical fiber transmission to provide a variety of services over Ethernet. It is also called EPON.Ethernet Passive Optical Network
