FG500

Fiber and coating geometry measurement system that measures core, cladding and coating diameter together with non-circularity and eccentricity.

FG500

Technical overview

The FG500 measures the physical dimensions of the fiber - core, cladding and coating diameter, non-circularity and eccentricity - using high-resolution optics. PFO states that calibration follows IEC guidance and uses calibration artefacts supplied by, or traceable to, the UK National Physical Laboratory (NPL). The system can be bought as a complete solution or in a reduced configuration covering coating only or fiber only. No numeric measurement ranges, resolutions or accuracies are published on the site or in the brochure.

Features

  • High-resolution optics for accurate calculation of fiber dimensions
  • Applicable to most fiber types - standard, NDS, NZDS, DC, bend-insensitive and multi-mode variants
  • Calibration follows IEC guidance using artefacts supplied by or traceable to the UK National Physical Laboratory (NPL)
  • Flexible configuration - complete solution, or coating-only or fiber-only reduced capability
  • PECON instrument control software
