Latest resource provides clarity on splitter terminology and deployment strategies for efficient FTTx networks.

The Fiber Broadband Association announced the release of its latest resource in its Fiber 101 Series, “Introduction to Passive Optical Network Splitter Architectures,” developed by the fiber broadband association (FBA) Technology Committee. The purpose of the guide is to demystify the terminology, configurations, and best practices associated with PON splitter deployment. This foundational document explores how splitter architecture choices impact fiber counts, splicing, and customer connections while setting the stage for a more detailed follow-up analysis of centralized versus distributed splitting architectures.

“The splitter architecture selected for a Passive Optical Network directly influences the cost-efficiency and scalability of deploying and maintaining Fiber-To-The-X (FTTx) networks,” said John George, Senior Director of Solutions Engineering and Fusion Splicers at OFS. “With the current scale of fiber deployment, providing clear, actionable insights is essential to help service providers, utilities, and other stakeholders build smarter networks that serve more communities. This guide reflects FBA’s commitment to equipping the industry with knowledge and resources.”

The guide introduces key concepts and configurations for splitter deployment, including:

  • Centralized splitter architectures, where splitters are housed in a central office or Fiber Distribution Hub (FDH).
  • Distributed splitter architectures, which place splitters closer to customers and pedestals or closures.
  • Technical considerations such as power split ratios (e.g., 1x32, 1x64) and their implications for network performance.
  • Emerging practices like unbalanced splits.

“Our members have voiced a need for greater clarity around PON splitter terminology and deployment methods,” said Deborah Kish, Vice President of Research and Workforce Development at the Fiber Broadband Association. “This guide serves as a shared foundation for understanding and deploying PON splitter architectures, enabling informed decisions that will drive successful fiber broadband initiatives.”

This guide is the latest addition to FBA's library of resources designed to accelerate digital equity and connectivity through fiber broadband. For more insights on fiber broadband trends and industry developments, sign up for the Fiber Broadband Association’s weekly newsletter here.
