Chromatic Dispersion Testers for High- Speed Fiber Networks
Data Center Test’s chromatic dispersion testers help optimize long-haul and high-speed fiber links by identifying signal delay and dispersion issues
Overview
At Data Center Test, our Chromatic Dispersion Testers deliver precise characterization of dispersion in optical fiber networks—helping utilities and network providers ensure signal integrity, particularly in high-speed and long-haul transmissions. These tools identify the effects of varying wavelengths traveling at different speeds, which can distort high-bandwidth signals over distance. Based at Advance Labs in Canoga Park, California, Data Center Test stands out as a trusted provider of fiber testing solutions that combine laboratory-grade accuracy with field-ready portability. Through cutting-edge research, rigorous QA, and expert customer support, we empower infrastructure teams across North America to diagnose and mitigate signal distortion for resilient utility communication

Case Studies
Case Study 1 – United States: Texas Utility Backbone Upgrade
A utility provider in Texas used Data Center Test’s Chromatic Dispersion Testers to validate a 180-mile Fiber backbone intended for a high-speed smart grid rollout. The tool helped identify dispersion anomalies that were previously undetected, enabling precise Fiber replacement and a 20% boost in signal clarity
Case Study 2 – United States: Florida Substation Fiber Optimization
During a high-voltage substation upgrade in Florida, engineers deployed Data Center Test testers to measure dispersion in multi-segment Fiber runs. The results led to adjusted amplifier spacing, reducing latency and enhancing performance without additional Fiber buildout
Case Study 3 – Canada: Smart City Fiber Backbone Maintenance
A Canadian municipality implemented Data Center Test's Optical Power Meters in their fiber maintenance strategy. The meters helped detect low-signal sections before failure, extending fiber lifespan and reducing emergency repair costs by 50%
