Barriers to WDM Deployment on Military Platforms

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 Don't Help!! * Low-RIN EDFAs * WDM Requires Multiplexing and Demultiplexing Multiple Channels * EDFAs ALWAYS Degrade Analog Link Performance * EDFA RIN Must be Reduced Below -155 dB/Hz * 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 dB(sub 0) Crosstalk Suppression for 18 GHz Sidebands * High-Power WDM DFB Arrays * >40 milliWatt/Channel at RIN <-160 dB/Hz, < 1 MHz Linewidth.
