Defining the Edge in Smallworld FTTH Network Design

Designing an efficient FTTH network requires precise planning, and Smallworld GIS (Geographic Information System) is a leading software solution that telecom operators use for network design and management.

A critical aspect of FTTH design is defining the edge, the point where the service provider’s network ends and the customer’s premises begin. This blog explores how Smallworld helps in defining the edge in FTTH network design and why it’s crucial for a scalable and cost-effective deployment.

Understanding the "Edge" in FTTH Networks

In FTTH architecture, the edge refers to the demarcation point between the service provider’s fiber network and the customer’s internal wiring. Key components at the edge include:

Optical Network Terminal (ONT) – The device installed at the customer’s premises that converts optical signals to electrical signals for end-user devices.

Drop Cable – The fiber cable connecting the distribution point (e.g., a splitter or terminal) to the ONT.

Demarcation Point – The physical or logical boundary where the ISP’s responsibility ends, and the customer’s begins.

Accurately defining this edge ensures proper network planning, maintenance accountability, and service delivery.

How Smallworld GIS Helps Define the Edge?

Smallworld provides advanced tools for telecom network design, helping engineers visualize, model, and optimize FTTH deployments. Here’s how it assists in defining the edge:

Geospatial Network Modelling

Smallworld allows designers to create accurate geospatial models of the FTTH network design, including:

• Fiber routes (aerial, underground, or hybrid)
• Splice points and distribution hubs
• Customer access points (where the drop fiber connects to the home)

By mapping these elements, network planners can clearly identify the edge and ensure seamless connectivity.

Automated Design Rules

Smallworld supports rule-based automation, ensuring that:

• Drop cables meet length and loss budget requirements.
• Splitters are optimally placed to minimize signal degradation.

The edge (ONT location) is correctly positioned for easy installation and maintenance.

Integration with Outside Plant (OSP) and Inside Plant (ISP) Data

Defining the edge requires coordination between:

• Outside Plant (OSP) – Fiber cables, poles, ducts, and terminals.
• Inside Plant (ISP) – Customer premises equipment (ONT, routers, etc.).

Smallworld integrates both OSP and ISP data, ensuring a smooth transition at the edge.

Cost Optimization

By precisely defining the edge, Smallworld helps:

• Minimize excess fiber deployment.
• Reduce labor costs by optimizing drop cable lengths.
• Avoid service delays due to incorrect edge placement.

Best Practices for Smallworld FTTH Design

Standardize Demarcation Points – Ensure consistency in where the ISP’s responsibility ends.

Use Real-World Geodata – Leverage Smallworld’s geospatial accuracy for precise edge placement.

Automate Drop Cable Design – Implement rules to optimize fiber runs to customer premises.

Validate Network Feasibility – Use Smallworld’s simulation tools to test signal loss and performance.

Defining the edge in FTTH network design is crucial for operational efficiency, cost control, and customer satisfaction. Smallworld GIS services provides the tools needed to model, optimize, and validate the edge, ensuring a robust and scalable FTTH deployment.
