Description  
The Corning Lasertron QDAX is a fiber-optic receiver utilizing an InGaAs APD followed  
up with a fixed 4K Ohm transimpedance amplifier which offers superior sensitivity  
required in long-haul applications. Packaged in a 14-pin DIL, the QDAX is pigtailed with  
single-mode fiber and the amplifier has 50 Ohm output impedance.
