WebThe thin-film filters at the time consisted of single-band WDM channels that transmitted or reflected a single-signal channel, or sometimes a group of channels using an X-skip-Y OADM skip filter. Daisy-chaining individual bands or groups of bands sequentially also achieves the goals of WDM, but with several drawbacks, including requiring the ... WebTypical features include center frequency from C to above Ka band although custom devices are avaliable from 1 to 60 GHz. Bandpass filters pass desired frequency range and suppress the rest of undesired spectrum. Designed from 800MHz to 67GHz. High Repeatability - Thin Film manufacturing provides precise manufacturing performance; no tuning.
