In summary, negative dB in optical spectrum analyzer plots is a result of signal attenuation or loss. This can occur due to various factors such as fiber optic cable length, connector losses, and optical components in the system. Negative dB values indicate that the signal has weakened or decreased in strength, which can affect the overall performance of the system and may require troubleshooting to identify and resolve the issue.
