Optical Fiber Switchers

Description

For multi-channel sequential applications, tec5USA has developed a family of optical fiber switchers, known as optical multiplexers or “O-MUX”. tec5USA’s optical multiplexers are based on a unique patented micromechanical MEMS piezo concept and provide high flexibility, long-term stability and excellent repeatability. The switchers are available from 1:2 to 1:32 outputs, with a wide selection of multimode fiber types, materials, diameters (up to Ø800µm for best throughput), and connectors.

The optical fiber switchers are especially useful to configure multi-channel process analyzers where only one spectrometer is needed and connected to several probe outputs. Signals are acquired in a sequential manner. This setup is extremely cost-efficient for complex multi-point monitoring systems, such as Raman or NIR analyzers, as the spectrometer component can represent a significant part of the total system cost.

In the same manner multiple probes can be multiplexed to a single spectrometer, it is also possible to multiplex a light source to two, or more, probes. Relevant examples are the dispatch of a single 785nm laser to several Raman probes, or the distribution of a Xenon flash lamp to different flow cells.

Features

High long-term stability: >10^8 switching cycles.
Short switching times, even for larger fiber diameters (< 30 ms).
Excellent repeatability (< 0.03 dB).
Low insertion loss.

Advantages

Very broad spectral range and large multimode fibers make these O-MUX solutions perfectly fit for spectroscopy process applications.
Fibers can be solarization stabilized (UV grade, High –OH) to Low –OH (NIR grade), up to 800µm core diameters.
Total system cost reduction by utilizing only one detection platform, and connecting several inputs/outputs.
A modular design that can grow as more channels are introduced.
