Optoplex tunable optical filter, can be called the light tunable filter or tunable bandpass filter, is an integrated module that contains micro-optics and control circuit. When the tunable optical filter input port (IN) received optical signal containing a plurality of wavelength channels, you can choose according to the control instruction signal from one wavelength channel output port (OUT) outputs. Output channel wavelength (frequency) can send remote commands and built-in control circuit and firmware, optionally in the presence of all channels in one.

 

Optoplex tunable optical filter is based on micro-optical design patents and thin film interference filter coating technology. Can thin film filter coating technology and DWDM tunable optical filter system used in the thin film filter technology is widely used (filter) is very similar. Wavelength tuning is achieved by changing the incident beam angle of incidence relative to a membrane filter to achieve. Each device for covering a wavelength range (C or L band) were optimized. Standard tunable optical filter product family supports channel spacing of 100 or -50GHz.
