2650A/B Broadband Photodiode
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 monitors
Description
The 2650A/B provides the proven high performance
of our photodiode technology in a very practical,
cost-effective package. The 2650-series features
very high linearity and very low capacitance over a
1 GHz bandwidth. These broadband photodiodes are
housed in a small, environmentally rugged coaxial
package.
The 2650A/B broadband photodetector is designed
to provide the performance and flexibility needed to
meet the expanding applications of two-way commu-
nications networks. This photodiode is used today in
forward- and return path applications including AM-
VSB CATV, QAM 64/256, PON, FTTC, and FTTH
receivers

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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.
