Optical Spectrum Analyzer consists of a narrow-band tunable optical filter, a photo-detector and low noise, highdynamic range electronics, as schematically shown in Fig 1.

When a wide band spectrum is incident to the tunable filter, it allows a narrow band out of input light centred at a given wavelength to pass through the filter.

By altering the central wavelength of pass band of the tunable filter, the whole input spectrum can be scanned at highspeed and spectrum information of incident signal is detected sequentially. The photo detector converts the light passing through the filter into electrical current. The data processing unit process the data and then outputs the processed spectrum to the computer for further data analysis and measurements .

Software application

Easy to use zooming capabilities and Quick translation of the signal trace

3 Modes for Analysis
LASERS    : To characterize a DFB Laser source for ?( central,peak,mean), Peak Power, Frequency and FWHM
CWDM    : To Analyse CWDM Channels. Displays the Channel No. based on ITU Standards EDFA    : To Analyze an EDFA System

• Sweep Band Selection in Custom Mode or ITU Band
• Displays the Plot in Frequency or Wavelength
• Save the graph in JPEG format
• Save the scanned data in excel format
• Save the extracted Results.

Software application

•   Plots the Wavelength or Frequency v/s Amplitude Trace   Clears all previous Data.
•   Scans for the Wavelength or Frequency once
•   Scans for the Wavelength or Frequency repeatedly every 1 sec.   Measures the Peak Power in dB
•   Displays the parameters of the selected wavelength with highest peak
•   Displays all the results, above the set threshold value in the Result window Two set of Markers to measure the ( ?(,)Δ?), power and Δ power.
•   Identify the CWDM Channel No (as per ITU Standards),
•   Displays all results
