The 2651 provides the proven high performance of EMCORE’s photodiode
technology in a very practical, cost-effective package. The 2651A features high
linearity and low capacitance over a 1 GHz bandwidth. The extended bandwidth
2651E offers high linearity and low capacitance up to 3 GHz. These broadband
photodiodes are housed in a small, environmentally rugged coaxial package.
The 2651 broadband photodetector is designed to provide the performance and
flexibility needed to meet the expanding applications of two-way communications
networks. This photodiode is used today in forward-and return-path applications,
including AM-VSB CATV, QAM 64/256, PON, FTTC and FTTH receivers.
The 2651A and 2651E photodiodes are compliant with all criteria of the Restriction
of the Use of Hazardous Substances in Electrical and Electronic Equipment
(RoHS) guidelines 2002/95/EC
