Description:

The DSC-R411 is a high-gain PIN + Transimpedance + Limiting amplifier ideally suited for both singlemode & multimode digital applications up to 43 Gb/s. The R411 is available in two GPPO packages, one of which is compliant to the 40G XLMD MSA (multi-source agreement). Due to its high conversion gain of 900 V/W and differential GPPO RF outputs, the R411 can be connected directly to commercial CDR / DEMUX modules. The R411 also offers a high optical overload of > +2 dBm, a very low power dissipation of 200 mW, and utilizes Discovery's high-reliability InGaAs photodiode technology.
