Koshin Kogaku Co., Ltd

TMUX is a wavelength tunable 3-port module applicable to the add-drop module or the multiplexer/demultiplexer.
By combining more than one module, the equipment which combine/split the prulal wavelength is achieved.




We provide customized modules for other wavelength bands, please contact us for detail.

Example of characteristic


■An accurate wavelength adjustment by implementing micrometer mechanism.

The wavelength is adjusted by rotating the filter cassette by using a micrometer.
A precise wavelength adjustment is possible.


■Research and development for the communication.

For test and selection of various filters.
For research and development of optical fiber communications.


A particular one channel can be selected from WDM by using BPF.
The wavelength to be selected can be adjusted by rotating the filters.
