I. Amplified High Speed Fiber Photodetector Overview
EOT’s Amplified High Speed Fiber 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. Figure 1 below identifies the main elements of your
Fiber Photodetector.

When terminated into 50Ω into an oscilloscope, the pulsewidth of a laser can be measured. When
terminated into a spectrum analyzer, the frequency response of a laser can be measured.
II. Operation of your EOT Amplified High Speed Fiber Photodetector
A. Caution: Eye safety precautions must be followed when utilizing any equipment used in the vicinity
of laser beams. Laser beams may reflect from the surface of the detector or the optical mount and
caution must be exercised.
