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.

Splitter Architectures

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 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.

centralized splitting

Distributed Splitting

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 splitting

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.

Closures and Splitters

fiber optic splice closures

Fiber Optic Splice Closures

The Fiber Optic Splice Closure is a highly reliable outdoor rated enclosure that holds devices that join cables together. The closure may house and protect fusion splices, splitters, adapters, or connectors. It can be aerial or pole mounted and can also be directly buried. This closure accommodates factory terminated drop cables which can be plugged into splitters or distribution ports and also can support branching to lower count cables, drop cables, or joining like count cables. With    6 cable ports, optional accessories, and splitter trays, the closure supports up to a maximum of 96 splices.

ruggedized plc splitters

Ruggedized PLC Splitters

OFS combines optical splitter and packaging expertise in a compact, ruggedized planar lightwave circuit (PLC) Splitter for FTTx applications. These splitters offer excellent optical performance in a flexible and easy-to-manage package allowing for rapid installation into cabinets, pedestals, or closure splice trays. The Ruggedized PLC Splitter may be snapped into existing splice trays and features unjacketed optical fibers to improve reliability vs. bare PLCs taped into trays with bare optical fibers. It allows reliable, cost-effective incremental growth, and simplifies fiber routing. It is most commonly used in distributed split configurations.

SlimBox™ Drop System

SlimBox Drop System

The SlimBox Drop System supports compact plug and play connections to homes, buildings, or small cells. FIGURE 11 shows the various components used to install this system. As mentioned earlier, the SlimBox Drop Terminal can be pole, pedestal or aerial mounted to terminate outside plant cables. The end point can then be connected using EZ-Bend® 4.8 Cable Assemblies. As described earlier, the EZ-Bend 4.8 Cables can be used outside and in the building or home. Alternative solutions are available to deploy within a unit as described in a later section for In Unit and Apartment Installations.

SlimBox Drop Terminal

The SlimBox Drop Terminal can be used with the EZ- Bend 4.8 mm or Mini LT Flat Drop Cables for an easy- to-deploy plug and play system.
It can accommodate up to 16 drop cables, and can hold up to a 1×16 splitter, making it an excellent choice for distributed split architectures. It can also function as a splice closure, holding up to 48 individual splices. The terminal can be pole, pedestal or aerial mounted, but is not recommended for underground deployment in a handhole.

EZ-Bend® Multifiber Drop Bundle

ez bend® multifiber drop bundle

Buildings can present a multitude of challenges. Some buildings may lack pathways or risers, requiring expensive core drilling, or the pathways may be restricted in size or contain other wiring. In addition, building owners and residents want cables and components to be installed quickly and invisibly.

EZ-Bend® Multifiber Drop Bundle

The EZ-Bend Multifiber Drop Bundle is a facade cabling system that mounts on the outside of buildings then can reach inside to connect subscribers. It provides the high performance advantages of single optical fiber EZ-Bend assemblies with the added benefit of installing from 3 to 12 assemblies at one time. This solution is ideal for older buildings that would otherwise require expensive internal pathway creation, and can be up to 3 times faster and less expensive to install than interior cabling in such buildings.
After installation a factory installed and connectorized coil of EZ-Bend drop fiber optic cable will be near each subscriber entry point. When the subscriber requests service, the connector on the end of the coil can be pushed through the wall, stapled if needed, and plugged into the optical network terminal (ONT). The other end of the Bundle is unconnectorized for splicing into the Fiber Distribution Terminal (FDT) that is located at the ground floor (feed-up method) or top floor (feed-down) of the building. An additional strength member is installed in the feed-down method for weight management of the cable bundle.

V-Linx Spool and Play Solution for MDU and Business

The V-Linx Spool and Play Solution is a versatile plug and play in building optical connectivity system that can be easily and cost-effectively scaled for medium to large buildings.

FIGURE 12 shows the various components used in the V-Linx Solution. From the building entrance, outside plant cables are connected to a wall-mounted V-Linx iFDH inside the building. The V-Linx FDH can support us to 144 individual optical fibers (using up to 4 1×32 splitters) with a single optical fiber per unit.

For medium sized buildings, a V-Linx Terminal is installed in the floor telecommunications closets. For medium sized buildings, a V-Linx Terminal is installed in the floor telecommunications closets. Each terminal can support up to 12 subscribers with SC connectors, or 24 subscribers with LC connectors. The terminals are equipped with a pre-terminated stub cable that is plugged into the V-Linx iFDH. A fiber management spool is included on the terminal to manage slack.

In large buildings, the V-Linx Combiner may be used to aggregate the V-Linx Terminals from up to six terminals or 72 individual optical fibers. The combiner is configured with factory pre-terminated and tested AccuFlex®+ Optical Ribbon Interconnect Cable Assemblies with MPO connectors.

The V-Linx Solution can be installed quickly without any fusion splicing, and uses less riser space than alternative solutions, making it ideal for MDU and Fiber-to-the-Business (FTTB) applications.

EZ-Bend® Solutions

Bends in a Typical MDU Residence

Typical living units have many corners around which an optical fiber may need to be conformed to reach the ONT. OFS EZ-Bend Solutions can be bent around up to 50 corners with negligible signal loss. Ordinary bend insensitive solutions may produce excessive loss with just a few bends.
The fiber path shown below is an excellent application for the InvisiLight Solution, shown later in this Solutions Guide.
