Abstract:
1. A system optics card comprising: a substrate; an electrical backplane connector supported by the substrate and connectable to a card-holding chassis; a drop filter supported by the substrate and configured to demultiplex a plurality of network channels from a network, and thereafter to identify at least one of the network channels destined for a client device communicating with an optical converter card and to direct the identified channel to a drop output port connected to the optical converter card and to direct the network channels destined for another system optics card to an express output port; an add filter supported by the substrate and having a first light combiner configured to combine channels from add input ports, at least one of which is connected to the optical converter card, and transmit the combined channels to a second light combiner configured to combine the combined client channels with channels from an express input port and transmit all the combined channels to the network; a mechanical front panel supported by the substrate and having at least one of the express input and output ports; and a power supply supported by the substrate.
