Tunable Fiber optical filter

Manually tunable optical filter for manual adjustment of the central wavelength in the area of 1550 nm (C-band). The maximum tunable range is more than 15 nm. The filter is based on the compression of FBG (Fiber Bragg Grating) through the accurate micrometric head which allows fine tuning resolution of 70 pm

 

 

Features
 

● Manually tunable optical filter
● Tunable range > 15 nm
● Manual adjustment of the central wavelength optional in the C-band (1520 – 1570 nm)
● FWHM optional 0.2 – 0.5 nm
● Fine tuning resolution 70 pm

 

 

 

Applications

 

● Wavelength selection form a broadband light source. 

● Noise suppression e.g. in EDFA amplifiers and transmission systems with tunable wavelength. 
● Telecommunications - channel selection in WDM systems. 
● Designed for laboratory and testing purposes.
