Data Sheet, Rev. 1 April 2001 2650A/B Broadband Photodiode Description The 2650A/B provides the proven high performance of our photodiode technology in a very practical, cost-effective package. The 2650-series features high linearity and low capacitance over a 1 GHz bandwidth. These broadband photodiodes are housed in a small, environmentally rugged coaxial package. Features ■ Low capacitance, ≤0.6 pF ■ 1 GHz flat response, ±0.5 dB ■ High responsivity: — ≥0.85 at 1310 nm — ≥0.95 at 1550 nm Applications ■ Forward-path and return-path broadband video transport ■ EDFA/network monitors The 2650A/B 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 AMVSB CATV, QAM 64/256, PON, FTTC, and FTTH receivers. Data Sheet, Rev.1 April 2001 2650A/B Broadband Photodiode Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
