In this scenario, the splitters are located in the central ofice or OLT location, shown in the blue circle. This architecture is similar to a “point to point” network, since one fiber is needed fo...

The splitters are stand-alone, not co-located with other splitters. In this scenario, the splitter is most often located in a closure or pedestal in the outside plant.

The first crucial architectural decision for the PON network is that of optical splitter placement. The centralized approach uses single-stage splitters located in a central hub in a star topology.

The first-stage optical splitter is placed in the community optical distribution box, and the second-stage optical splitter is placed in the corridor. Cascaded distribution features low user access

In cascaded splittings, the optical splitter A ( the first level) is usually installed near the central office end, and the optical splitter B (the second level ) is usually installed near the user end,

From the structure, splitter placement in ODN is very crucial. there are generally two types of splitter placement in ODN network, centralized splitting and cascading splitting. The centralized splitter uses

The size of the Access Node is determined by the size and capacity of the FTTH area to serve in terms of users and future upgrades. Access Nodes are usually housed in Central Offices

In a centralized split network, a 1x32 splitter is typically housed within a fiber distribution hub (FDH). A single fiber connects this splitter to the optical line terminal (OLT) at the central office.

These single-stage fiber splitters can be placed at several locations in the network or housed at a central location. In most cases however, the centralized fiber splitters are placed in the outside plant (OSP)

Concentrated optical splitting means that the OLTs are placed in the central computer room, and all the optical fibers are led out from the central computer room, or a small amount of feeder cables are led

What is PON design? A passive optical network is a fiber-based network architecture that uses unpowered (passive) splitters to enable a single optical fiber to serve multiple endpoints. It
