DAP Card

Dear friend!
Please rest assured that we'll be back with an answer shortly.

Dear friend!
1. Whether the transmit optical signals of the DAP board are disabled depends on the receive optical power. When its input power is -60dB. The output optical power must be –60 dB, which means that there is no optical signal. It is preliminarily confirmed that the DAP board has no hardware fault.
2. According to the screenshot, the optical power of the OUT port on the WSDM9 board is too low (-34 dB). You are advised to increase the output optical power of the OUT port by using the variable optical attenuator of the WSDM9.
3. If the input optical power of the DAP board is too low, the VOA connected to the DAP board can be abandoned. That is, the OUT port on the WSDM9 is directly connected to the IN port on the DAP board.
Thank you!
