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.
