1550nm single mode bandpass fiber filter 3dB passband 20nm without connector

Idealphotonics' fiber filters use a special fiber structure to select or filter out specific wavelengths of light from different wavelengths. We can provide filter devices with different optical power versions according to user needs, which can be used in dense wavelength division multiplexing fiber communications, frequency division multiplexing fiber communications, spectrum testing, fiber sensors, fiber lasers and fiber amplifiers. If you need to customize the center wavelength, operating temperature or specific working bandwidth, please contact us for customization.

Product features：Wide passband range、 Low insertion loss、 High passband isolation、 Stable operating characteristics

Application area：Fiber amplifier、 WDM&DWDM system、 Fiber equipment、 Fiber laser
