TFM/FC contains an optical filter mounted on a cassette. By exchanging the cassette, TFM can change its spectral characteristics including the tunable wavelenth range. The center wavelength can be tuned until 20nm as the optical filter inside is turned by rotation of the equiped micrometer. The micrometer enable the fine wavelength tuning.

Product Features

Arbitrary spectrum characteristics can be formed by using 2 optical filters.




■ For Development of Optical Communications Syetems

Just connecting through optical connectors, TFM operates as an optical filter.  By exchanging the filter cassette, an arbitrary characteristics is achieved.

■ For Wavelength Selection in the WDM Systems

TFM can extract only one wavelength from WDM by using band pass filter. The extracted wavelength is arbitrarily selectable by turning the filter cassette on which an optical filter is mounted.

■ For simple narrow-band wavelength tunable light source

A simple narrow-band wavelength tunable light source can be constructed by combining TFM with LED light source or ASE light source. The tunability is acieved by turning the filter cassette.
