Abstract:

Desperately Needed Developments to Enable Replacement of RF Switches Low Insertion Loss, High-Speed Switches 10 millisecond SONET Switching is Too Slow for Military Applications 10 microseconds is Typical Requirement 100 nanoseconds for High POI Appl. Narrow Bandwidth FP, High-Speed Switches Dont Help Low-RIN EDFAs WDM Requires Multiplexing and Demultiplexing Multiple Channels EDFAs ALWAYS Degrade Analog Link Performance EDFA RIN Must be Reduced Below -155 dBHz High Crosstalk Suppression Between WDM Channels Optical Switches for Tunable lambda-Filtering Easy for Narrowband RF Signals 1 GHz Difficult for 18 GHz and Higher Sidebands Fiber Bragg Gratings are the Only Demonstrated Technology to Achieve 35 dBsub 0 Crosstalk Suppression for 18 GHz Sidebands High-Power WDM DFB Arrays 40 milliWattChannel at RIN -160 dBHz, 1 MHz Linewidth.
