CD500
Chromatic dispersion measurement system for optical fiber and cable manufacturing. Uses a temperature-stabilised solid-state monochromator with DSP-based detection.
Technical overview
The CD500 sets and holds its measurement wavelength using a solid-state monochromator driven by a digitally derived RF frequency signal, which PFO states gives picometer-level wavelength precision and stability. Broad-band SLED sources cover 1250-1650 nm, and DSP-based acquisition is used to keep results low-noise and drift-free. The platform is modular: the same hardware can be configured for PMD, strain, macrobending loss and cut-back spectral attenuation. PFO lists it as applicable to standard, NDS, NZDS, DC, bend-insensitive and multi-mode variant fibers.
Features
- Solid-state construction for stability, accuracy and low ownership cost
- Broad-band SLED light sources with wide spectral coverage
- Fully developed control software with user-programmable automated high-speed measurements
- Applicable to most fiber types - standard, NDS, NZDS, DC, bend-insensitive and multi-mode variants
- Variant: tuneable laser version for higher dynamic range and narrower spectral resolution
- Variant: PMD version adding fixed analyser and/or interferometry methods
- Variant: strain option monitoring length and power change during mechanical stressing
- Variant: macrobending loss option with low-frequency power detection
- Variant: external plug-in spectral attenuation module using the cut-back method
- PECON instrument control software
