Examples of the use of fiber optic special components in the most diverse application areas are:

  • Measuring probes in chemical industries
  • Fiber measuring systems for astrophysics
  • Fiber feed-throughs into a vacuum chamber for signal transmission
  • Fiber systems for temperature measurement in the high temperature range
  • Offshore measuring systems in wind turbines or on oil platforms

Our products and systems are the best choice for the measurement of:

  • Reflection, emission, transflectance, transmission
  • Physical, dynamic and geometric parameters such as temperature, pressure, expansion
  • Raman, Rayleigh and Brillouin scattering, fluorescence, etc.

Fiber optical switches

Optical switches for singlemode and multimode applications

LEONI's fiber optical switches are based on a proprietary micro mechanical / micro optical concept. This guarantees superior properties, wide flexibility for many applications and highest long term reliability. The switches are available for broad wavelength ranges – from the visible to the infrared range – and with various fiber types. 

LEONI's switches have been developed to serve applications with the most demanding requirements in the telecommunications, testing and measurements as well as the production and process monitoring and biomedical sector.

Application examples are:

  • Beam guiding systems for confocal and laser scan microscopy
  • Fiber optical tension and temperature sensors
  • Fiber optical measurement systems

Integration of our switches with any existing system is easy due to a maximum input power of 450 mW and standard interfaces. In the EOL 1x16 switch for example, high channel numbers can be reached without cascading, while cascading allows almost any desired combination to be possible. 

Fiber optical splitters

Planar lightwave circuits (PLC) are based on LEONI's planar waveguide technology that allow maximum performance and exceptional long-term stability.

The singlemode standard product portfolio includes low-loss and broadband 1xN and 2xN splitters with up to 64 channels. The range of applications is broad, including sensor technologies and optical power transfer. Based on customer application needs, products can be developed for the near infrared wavelength range (NIR: 780 nm – 1060 nm) and also for the visible wavelength range (VIS).

LEONI's splitters are characterized as follows:

  • Very low insertion loss
  • High uniformity
  • High extinction rate
  • Lowest PDL
  • Widest bandwidth (780 nm – 1060 nm or 1260 nm – 1650 nm)
  • Small, rugged metal housing
  • Any fiber assembly
  • Own connectors
  • Exceptional long-term stability – tested according to Telcordia GR 1209 and 1221
