摘要： Methods and apparatus for allowing a dense wave division multiplexing (DWDM) line card w to function as an add/drop multiplexer (ADM), a transponder, and a muxponder are disclosed. According to one aspect of the present invention, a line card suitable for use in a network to aggregate signals of different line rates for transport includes a first arrangement having ADM functionality, a second arrangement having transponder functionality, and a third arrangement having muxponder functionality. The line card also includes hardware that facilitates communication between the arrangements, as well as a plurality of ports arranged to receive a signal and to provide the signal to the hardware.

摘要： A device and method for cooling chemical smoke for creating a low lying fog effect comprises first and second chambers arranged in heat exchange relationship, the first chamber comprising an open-ended conduit adapted for maintaining a flow of chemical smoke therethrough, the second chamber adapted for receiving liquid CO.sub.2 under pressure and including vent openings for venting gases from the second chamber into the first chamber for maintaining the second chamber at ambient pressure, the liquid CO.sub.2 transforming to dry ice in situ, and a liquid CO.sub.2 supply system for connecting a source of liquid CO.sub.2 under pressure to the second chamber, whereby the chemical smoke flowing through the first chamber is cooled by the dry ice in the second chamber. Thermal sensor means sense the temperature in the second chamber and control a liquid CO.sub.2 flow control valve in the liquid CO.sub.2 supply system.
