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.
