2651A/2651E Broadband Photodiode

DATASHEET | FEBRUARY 2012

FIBER OPTICS

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.

Applications

Forward-Path and Return-Path

Broadband Video Transport

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
