Description
The KY-PDM series photoreceiver without amplifier adoptshigh-speed and high-linearity analog PIN detector. It has a direct 50 ohm coupled output at the back end,with fast response, low noise and flat response. The module is powered by battery,and the input optical interface is optional for optic fiber or space incidence. This series of products are suitable for applications where the optical power is in the order of mW, such as pulse light waveform detection, pulsed laser measurement and other fields.
