Laser Spectrum Analysis

The laser spectrum analysis is used to analyze an optical signal and to determine parameters such as optical powers, central wavelengths and optical signal noise ratios (OSNR) 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, click the board and select Configuration > Laser Spectrum Analysis from the Function Tree.
In the NE Panel, right-click the board and select Laser Spectrum Analysis.

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.
Standard Wavelength (nm)/Frequency (THz)	For example: 1529.16/196.063	Displays the result of the optical performance data after spectrum analysis. Standard Wavelength (nm)/Frequency (THz): Indicates the standard central wavelength of the optical path.
Central Wavelength (nm)/Frequency (THz)	For example: 1529.16/196.050	Indicates the actual central wavelength of the optical path.
Wavelength Deviation (nm)	For example: -0.2	Deviation between the standard wavelength and the actual wavelength.
Optical Power (dBm)	For example: -60.0	Displays the optical power currently.
OSNR(dB)	For example: 25.6	The optical signal noise ratio of the optical path.
Spectrum Data	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. 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.
