Telecom Band Pass Filters

Bandpass filters (BPF) are used to transmit one or more bands of wavelengths while blocking (or reflecting) adjacent wavelengths over extended ranges. Typical applications include wavelength division multiplexing/demultiplexing; channel bandsplitting;

Iridian Telecom Band Pass Filters Advantage:

Iridian's bandpass filters are designed to have a very sharp transition between the reject and pass bands while maintaining very low insertion loss and pass band ripple. Our proprietary deposition technology allows our bandpass filters to meet even the most demanding specifications.
