A passive optical network (PON) is a telecommunications technology used to provide fiber to the end consumer, both domestic and commercial. A PON's distinguishing feature is that it implements a point-to-multipoint architecture, in which unpowered fiber The ITU-T G Gigabit-capable Passive Optical Networks (GPON). offering Gigabit Passive Optical Network or GPON GPON is the core underpinning of Verizon's FiOS of GPON campus network architecture is presented. Components and Architecture of GPON FTTH Access Network. PON (Passive optical network) based FTTH access network is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve premises.

By utilizing two main access points at our main office in Columbia and another in Fulton, and distributing those signals to our fiber huts and on to passive equipment cabinets, we can provide service for a higher volume of customers while using less powered equipment on a redundant network that can stay up and running in the event of an equipment failure.
A grant is permission gpon architecture use a defined interval of time for upstream transmission. The grant map is dynamically re-calculated every few milliseconds.
Some services — POTSfor example — require essentially constant upstream bandwidth, and the OLT may provide a fixed bandwidth allocation to each such service that has been provisioned. DS1 and some classes of data service may also require constant upstream bit gpon architecture.
But much data traffic, such as browsing web sites, is bursty and highly variable. Through dynamic bandwidth allocation DBAa PON can be oversubscribed for upstream traffic, according to the traffic engineering concepts of statistical multiplexing.
Downstream traffic can also gpon architecture oversubscribed, in the same way that any LAN can be oversubscribed.

The only special feature in the PON gpon architecture for downstream oversubscription is the fact that the ONU must be able to accept completely arbitrary downstream time slots, both in time and in size.
If the ONU has no traffic to send, it transmits idle frames during its excess allocation.
Although there are other technologies that could provide fiber to the home, passive optical gpon architecture PONs like GPON are generally considered the strongest candidate for widespread deployments. This transmission can reach up to 20 km starting from the central office running to the user.

Voice, video, and data traffic must all be delivered across the single GPON downstream wavelength. But passive optical network have various gpon architecture, that gpon architecture consume less power, have low maintenance and less interference problems.
The OLT gpon architecture in all of the optical signals in the form of beams of light from ONUs and will convert it to an electrical signal.
