The Dual Ports APD modules include Two separately APD detectors enable very low light levels to be detected quickly and simply in a variety of applications such as laser radar, rangefinding, data transfer or biomedical analysis.The APD modules are based on low-noise avalanche photodiodes made of either silicon or InGaAs with a built-in pre-amplifier and high voltage supply. A temperature compensation function allows the APD to be operated at constant gain across a wide operating temperature range. 

Instructions

1. The power supply voltage of the module is 5V, and the maximum power supply current is 0.8A.

2. 5VDC is the power interface; Input is the optical input interface; RF is the RF output interface.

3. Before accessing the input end, ensure that the end face is clean to prevent dirt from affecting the measurement results.
