FTTx PON Architectures
Centralized, Distributed and Distributed Cascaded Splitting
The Fiber Distribution Point aggregates many subscriber distribution optical fibers into a few optical fibers in the feeder that connects to the CO or Head End and consists of Cabinets, Pedestals, and Splitters.
For PON networks, product selection is highly dependent on which splitter architecture is used in FTTx deployment. Guidance on splitter architecture selection is provided below. OFS Solution Engineers are available to provide detailed guidance optimized for each customers’ unique needs. For active Ethernet networks, a powered Ethernet switch is used in place of splitters, feeder cables connect to the switch in a cabinet, and distribution cables connect the switch to downstream endpoints.
A typical PON network consists of the Optical Line Terminal (OLT) in a central office, head-end or cabinet, connected by a feeder cable to optical splitters, and then to distribution cables downstream in the network.
Choosing the right architecture depends upon end-user density, projected subscription rates, and distance from the OLT. Splitter placement is important in FTTH design as it can significantly affect plant and electronic costs.
Three common types of splitter architectures used in FTTx deployments are:
- Centralized splitting
- Distributed splitting
- Distributed cascaded splitting
Centralized architectures help to reduce total costs when relatively low take rates are expected. They can help defer capital costs by allowing for incremental OLT and splitter additions as subscriber counts increase
Centralized architectures co-locate a number of splitters in a central location, such as a cabinet for subscribers farther from the Central Office (CO), or in the CO for nearby subscribers.
A distributed splitting architecture is cost-optimized when medium to high subscription rates are expected. This architecture also has the added benefit of eliminating the need to find space for placing cabinets. Splitters are “distributed” throughout the network and placed enclosures or pedestals in the field or in
buildings. At each splitter location, there will typically be one or (at most) two splitters.
This type of architecture typically uses lower fiber count cables and requires less splicing. It also results in lower plant costs but incurs higher electronics expenses.
Distributed Cascaded Splitting
Distributed cascaded splitting, also called a double star, is a form of distributed splitting with the splitters “cascaded” in the network. For example, a typical distributed split architecture may use a 1X32 splitter in a closure. However, the cascaded version may consist of a 1X8 splitter at one location feeding four 1X4 splitters downstream at different locations, to achieve a 1X32 split.
This architecture is most commonly used in rural areas with long distances from the OLT to the subscribers, and medium to low densities. It results in fiber savings by minimizing the fiber count of the cable needed to serve an area. Splice closures or pedestals are commonly used to house and protect the splitters in a distributed cascaded splitting architecture.
Choosing A Splitter Architecture
Optimized to Fit Your Deployment
The following matrix details the advantages of the three approaches to splitting architecture. The cross-over points for subscriber density and take rate will vary depending on factors such as OLT port cost, labor cost, and others. OFS Solution Engineers can provide more detailed guidance optimized for each customers’ needs.
The Distribution and Drop Network
Reaching and Connecting the Subscriber
Providers typically use a combination of aerial and underground solutions to connect the last mile in a network to individual homes, buildings, or cell sites. A variety of factors including climate and existing infrastructure can influence solution selection.
OFS offers a complete portfolio of aerial and underground solutions including terminals, integrated splitters, and drop cables to connect to the demarcation point of individual homes, buildings, or cell sites. From that location, a number of solutions can be leveraged to take optical fiber into the home or building to provide 100 times faster Internet.
