Laser Spectrum Analysis

The laser spectrum analysis is used to analyze an optical signal and to obtain parameters such as optical power, central wavelengths and optical signal noise ratios (OSNRs) of the optical paths. You can use this function to determine the transmission quality of the current optical signal. In this user interface, you can query and print the spectrum analysis result of the optical signal.

Navigation Path

In the NE Explorer, select the board and choose Configuration > Laser Spectrum Analysis from the Function Tree.
In the NE Panel, right-click the board and choose Laser Spectrum Analysis from the shortcut menu.

Parameters

Field	Value	Description
No.	For example: 1	Displays the serial number for the signal of each wavelength.
Port Number	For example: 1(IN1)	Displays the port number of each path of the spectrum analysis board. For MCA4, there are four ports. For MCA8, there are eight ports.
Board Type	For example: OAU	Displays the type of the peer NE connected to the local NE.
Compensation Power (dBm)	For example: 20	Displays the recommended compensation power value according to the local and peer NE types.
Spectrum Data	Wavelength No, Standard Wavelength (nm)/Frequency (THz), Central Wavelength (nm)/Frequency (THz), Wavelength Deviation (nm), Optical Power (dBm), OSNR (dB)	Displays the result of the optical performance data after spectrum analysis. Wavelength No: indicates the wavelength No. of each optical path. Standard Wavelength (nm)/Frequency (THz): indicates the standard central wavelength of the optical path. Central Wavelength (nm)/Frequency (THz): indicates the actual central wavelength of the optical path. Wavelength Deviation (nm): deviation between the standard wavelength and the actual wavelength. Optical Power (dBm): the optical power of the optical path. OSNR(dB): the optical signal noise ratio of the optical path.
Spectrum Waveform	None	Displays spectrum data in graphics.
Profile	None	Displays the spectrum profile of the optical signal.
X-Axis Frequency	Checked, Unchecked	Specifies that the X-axis for the Spectrum Data, Spectrum Waveform, and Profile represents the frequency.
X-Axis Wavelength	Checked, Unchecked	Specifies that the X-axis for the Spectrum Data, Spectrum Waveform, and Profile represents the wavelength.
