Note 1: Tested using the phase noise method, similar to the Lorentz linewidth for a simple test using the delayed self-heterodyne beat method.

Note 2: Typical values are related to external operating temperature.

Note 3: The current value of the module when the TEC is in high current working state during startup. In order to ensure normal startup, the power supply usually needs to provide a current of 2A.
