WDM Thin Film Filter

Wavelength Division Multiplexer (WDM) is used to combine light with different wavelengths into a fiber or separate an optical signal into two fibers. It is based on thin film filter technology and metally packaged, which can be used in high-power applications in WDM systems. -WDM Thin Film Filter (TFF)- Features Low insertion loss High return loss High directivity Environmentally stable Optical path epoxy free Applications CATV systems DWDM systems Erbium-doped fiber amplifier (EDFAs)
