How to Address an Aging Fiber Plant
Register Now
As utility networks evolve to support higher data rates and increasingly complex applications, aging fiber infrastructure can quietly limit performance and reliability. Many legacy fiber systems—some dating back decades—were not designed for today’s bandwidth demands, making it critical to understand the underlying optical factors that impact network performance.
In this webinar, we’ll break down the key principles that influence fiber-optic systems, including attenuation, dispersion, reflectance, and optical return loss (ORL), and explain how they affect both legacy and modern fiber types.
Attendees will gain practical, field-driven insights on how to:
Identify performance limitations across existing fiber spans
Understand the differences between legacy and newer fiber generations
Diagnose signal degradation issues using proven techniques
Reduce reflectance and ORL to meet current performance standards
Implement cost-effective strategies to extend the life of existing infrastructure
Whether you’re upgrading an existing network or troubleshooting performance issues, this session will provide actionable guidance to help you maximize your fiber investment without unnecessary overbuild.
