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.
