The development of the BOSA has always had the goal of overcoming the problems of the existing optical spectrum analysers. They were either to bad in resolution, or too slow, or offered bad dynamic range.

      The BOSA is the reunion of real high resolution with high dynamic range at a time. And for a real time measurement .

• - 0.08 pm (10MHz) resolution
• - 80 dB dynamic range across the complete range   and for any span
• - C+L band
• - Real time measurements

• - Design and characterisation of lasers and   modulators; linewidth, sidebands description
• - Optical filters
• - DWDM
• - Research, manufacturing and quality test
• - Modulation effects, chirp, modulation spectrum
• - Microwave photonics
