The Cisco ONS 15454 fixed filter cards integrate 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 operational status. An icon on each faceplate is mapped to shelf-slot icons indicating the shelf slot where the card can be installed. All Cisco ONS 15454 fixed optical filter cards can drop and reinsert a wavelength without needing to regenerate the signal (optical bypass). This unique capability is supported at individual channel and band level and allows creation of multiring or mesh traffic matrixes using the available fixed filter cards.
