Abstract

The invention relates to a passive optical network optical power meter calibration device and a calibration method. The calibration device comprises three light sources, an adjustable optical attenuator, a standard optical power meter, a standard passive optical network power meter, an optical network unit and an optical line terminal. The three light sources are used for outputting continuous data flow optical power. Maximum output optical power of the wavelength of 1310 nanometers is no less than 0 decibel above 1 milliwatt (dBm). The output optical power of the wavelength of 1490 nanometers is no less than 0 dBm. Maximum output power of the wavelength of 1550 nanometers is no less than 20 dBm. When the continuous data flow optical power of the passive optical network optical power meter is calibrated, the adjustable optical attenuator is connected with the light sources. When bursting data flow optical power of the passive optical network optical power meter is calibrated, the adjustable optical attenuator is connected with the optical network unit of a passive optical network. The standard optical power meter is used for calibrating the continuous data flow optical power of the passive optical network optical power meter. The standard optical power meter is capable of being connected with the adjustable optical attenuator. The optical network unit and the optical line terminal are used for calibrating the bursting data flow optical power of the passive optical network optical power meter.

Description

technical field [0001] The invention relates to the calibration of an optical power meter, in particular to a calibration device and a calibration method for a passive optical network (Passive Optical Network, PON) optical power meter. Background technique [0002] JJG965-2001 Verification Regulations for Optical Power Meters Used in Communication stipulates the calibration method of general optical power meters used in communication. The calibration method is a direct comparison method, and its principle is as follows: Figure 1a with Figure 1b As shown, the output end of the light source 11 is connected to the input end of the adjustable optical attenuator 12. First, the output of the adjustable optical attenuator 12 is connected to the standard optical power meter 13, and the output wavelength and the output wavelength of the light source 11 are set. output power, set the wavelength of the adjustable optical attenuator 12, adjust the adjustable optical attenuator 12, rea...
