2651A/2651E Broadband Photodiode
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.
