Mark-Type Thermally Stable Standard 1525-1565nm

The Mark-ID Thermally Stable Photonic Filter from Xiaoxiao Photonics is based on advanced ETALON technology , incorporating unique optical and mechanical designs , along with advanced packaging technology. This ensures the stability of the filter's wavelength under extreme environmental conditions , including temperature and humidity . With our unique patented technology , the filter guarantees the wavelength's target accuracy within ITU +/- 1.25 GHz , and is available in selectable options . This ITU-aligned filter can be used for channel monitoring and wavelength locking in Wavelength Division Multiplexing (WDM) systems . We also offer special technology options for customers to choose specific wavelength accuracy . This thermally stable filter module can lock one or more consecutive adjacent wavelength peaks , forming a fixed wavelength marker . This wavelength marker helps client scanning systems determine their specific position within a wavelength range . The unique design of this filter ensures the precision of the standard , channel spacing , and operational wavelength , with a wide selection range . The thermally stable filter, designed for customer use , is highly compatible with various spectral applications , including telecom , wavelength reference and calibration , fiber optic sensing systems , testing and measurement , and laser wavelength stability control .
