ET-5000 10GHz 2µm Photodetector

Summary Box:

ET-5000/A 10GHz indium gallium arsenide (InGaAs) PIN and amplified photodetectors covering 800-2100nm, ideal for monitoring the output of high repetition rate, externally modulated CW lasers.

Description:

EOT’s >10GHz 2µm Amplified InGaAs Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current and a fixed gain transimpedance amplifier allowing measurement of <1mW input powers. When terminated into 50Ω into an oscilloscope, the pulse-width of a laser can be measured. When terminated into 50Ω into a spectrum analyzer, the frequency response of a laser can be measured. EOT’s >10GHz 2µm Amplified InGaAs Photodetectors come with their own wall plug-in power supply. Plugging a coaxial cable into the photodetector’s SMA output connector and terminating into 50Ω at the oscilloscope or spectrum analyzer is all that is required for operation. Fibre coupled (5000F) and Amplified (5000A) versions are also available.
