Description: You are buying a used Ando AQ4321D single frequency tunable laser source of 1520-1620 nm with instruction manual on a flash-Drive. This laser source is in excellent working and excellent cosmetic conditions. All functions on this laser source have been tested and they are perfectly operational. Pictures are taken from the actual item you are buying. Ando AQ4321D description:The AQ4321 system is the highly reliable optical source whose emission wavelength can be adjusted highly accurately. Its variable wavelength covers the WDM communication bandwidth in the1520 to 1620-nm range. The AQ4321D system is appropriate to optical amp measurement as its optical output is not interrupted even when its wavelength or optical output is changed. The system has the excellent basic performance such as high-speed sweep, stability, high SMSR and narrow linewidth. Its various wavelength sweep and optical output modulation are available. Also, fully remote control via GPIB or RS-232C are installed. Following testing are done on this laser source using a calibrated Burleigh WA-1600 wavelength meter, a calibrated Advantest Q8347 optical spectrum analyzer and a calibrated Newport 918D-IS optical power meter:1- It turns on properly and goes through a number of self-test and sub-wavelength calibration with success.2- I adjusted wavelength of this Ando laser source at 1520.000 nm, and using a Burleigh WA-1600 wavelength meter with accuracy of +/- 0.0002. The measurement discrepancy is well inside specs of this machine which is 0.015 nm.3- I test the single frequency operation of laser source using an Advantest Q8347 optical spectrum analyzer. Single frequency operation is observed (see image 10).4- I ran a high speed sweep of frequency. It was done successfully with no problem.5- I measured optical laser power output at the tip of the fiber of this laser source and observed followings: At 1520 nm, I measured the output power of +5.96dB, the Ando AQ4321Dspecs guarantees +3dB or more, so this laser source has more output power than specs defines at 1520 nm.At 1570 nm, I measured the output power of +8.01dB, the specs guarantees about +6dB, so this laser source has more output power than specs defines at 1570 nm.At 1620 nm, I measured the output power of +7.18dB, the specs guarantees about +6dB, so this laser source has more output power than specs defines at 1620 nm.Therefore, you can sweep the source for entire spectrum with constant power of 5.96dB.I concluded that this laser source meets all specs of the manufacturer.
