WebIn a stop band, the equivalent index of a symmetrical period is a pure imaginary; in a pass band, it is real. Equivalent indices are given for some commonly used periods. These may have values not possessed by any existing substance. These periods have proved useful in the design of optical filters and antireflection coatings. WebSep 19, 2016 · The Cisco ONS 15454 fixed filter cards are based on the ITU 100-GHz wavelength plan. Each card integrates software-controllable variable optical attenuators (VOAs), providing automatic node- and network-based power level management. The optical cards incorporate LEDs on the faceplate to provide a quick visual check of the card's …
