The FGC range is the complete solution for measuring the dimensions of standard and specialty fiber in both production and R&D environments.
FGC-GS measures fiber glass geometry for fibers up to 1000 µm diameter.
Features and Benefits
- Measures the widest range of fiber sizes and types – single unit solution means less bench space, reduced training
- Standards compliant – calibrated to international standards, ensuring confidence in its accuracy
- Production ready – reliable, repeatable, operator-independent results in seconds
High Image Quality
The FGC uses a Darkfield Imaging system which gives a clear image of the
fiber end face, and with our high quality optics and camera users are able to
measure the widest range of fibers, from standard fibers to specialty fibers.
Production-Ready Software
The FGC software allows users to quickly and easily get both core and cladding geometry measurements including diameter, non-circularity and concentricity. The software contains measurement templates for all standard telecoms fibers. Users can also create their own templates and measure many special fiber types including dual clad fiber, bend insensitive fiber, multicore fiber, polarisation maintaining fiber and many more.
| Polarisation Maintaining fiber |  | Octagonal fiber |  | Dual clad fiber |  |
| Micro-structured fiber |  | Multimode fiber |  | Multicore fiber |  |
The latest release v5.7 of FGC software is applicable to the FGC-GT and FGC-GS optical units.
| Feature | Benefit |
|---|---|
| MCF Measurement | Enables more flexible measurement of up to 19-core multicore fibers, including markers |
| Change of field of view | Enables change of field of view in main UI |
| Inner-outer Cladding Concentricity | Enables measurement of Inner-Outer cladding concentricity for dual-clad fibers |

Repeatability**
Core Diameter < 0.1 µm
Cladding Diameter < 0.15 µm
Core Non-Circularity < 0.5%
Cladding Non-Circularity < 0.1%
Core-To-Cladding Concentricity < 0.15 µm
*May be fitted with other customised wavelengths.
**Repeatability is measured on the FGC-GS using a single 20/400 µm fiber without removing it from the unit at 22°C.
