communications components key features ? high polarization extinction low drive voltage low fiber-to-fiber insertion loss 1550 nm operation the jdsu 2x2 interferometric switch is a high extinction, high speed switch. because the waveguides are polarizing, control of the input light polarization is required. switching speeds in excess of 1 ns are attainable. input and output fibers are polarization maintaining. applications ? nanosecond switching 2x2 high speed lithium niobate interferometric switch north america : 800 498-jdsu (5378) website : www.jdsu.com worldwide : +800 5378-jdsu typical frequency response, s21 typical return loss curve, s11 0 2.00e+08 4.00e+08 6.00e+08 8.00e+08 1.00e+09 frequency (ghz) relative detected rf (dbe) 42 43 44 45 46 47 0 2.00e+08 4.00e+08 6.00e+08 8.00e+08 1.00e+09 frequency (ghz) relative detected rf (dbe) 0 -5 -10 -15 -20 -25 -30 -35 -40
