SI diode with pre-amp
SI diode with pre-amplifier in chip, thus no need for externet TZA3023 pre-amp from TransimpedenceAmp http://sales.hamamatsu.com/en/products/solid-state-division/si-photodiode-series/with-preamp-cooler.php. Hamamatsu also manufactures photodiode modules, which combine a silicon photodiode and current-to-voltage conversion amplifier. Dedicated signal processing units are also available, this would be an alternative to the Philllips TZA3023/3033

APD modules
APD modules with 1Gig integrated detectors for use in FSO. http://sales.hamamatsu.com/en/products/solid-state-division/si-photodiode-series/apd-modules/c5658.php. See demo board - http://sales.hamamatsu.com/assets/pdf/parts_C/c10508_kacc1134e02.pdf
