WDM Filter

WDM Filter for 5G

Materion Precision Coatings has developed a wavelength-division multiplexing (WDM) filters for optical multiplexer module utilized in modern telecommunication equipment. Integrated into the optical multiplexer module, the filters are designed to provide you the high steepness of transmittance slopes in the transition zones between passband and stopband for near infrared wavelength. Our WDM filters are increasing overall transmission as well minimizing the temperature shift. It is flexible for spectrum design for various infrared wavelengths.

Benefits

• High transmission and low insertion loss
• Optimized spectral performance
• Steep cut-on/cut-off slopes
• Low temperature shift
• Excellent environment stability
• Compact size
• Cost effective solution for telecom optical module
• Customized designs possible

Applications

WDM filters provide high transmission for various infrared laser beam signal. Filters can be:

• Integrated in optical multiplexer module
• Placed in the optical path in WDM-Transceivers
