The measurement device consists of Agilent 8163B laser module and Agilent 81634B power/wavelength meter module, both of them are integrated into a single Agilent mainframe. Both modules are operated by a remote computer over the GPIB interface using MatLab software, which allows saving measurement data digitally. It allows us to measure the amplitude-frequency (wavelength) transfer curve of almost any optical component (filters, attenuators, isolators, optical chips, etc.), where we can launch and capture the optical signal. It is possible to sweep the Agilent laser source within its operational range (1470 nm to 1570 nm) with set wavelength step size and measure optical power and wavelength of the received signal using Agilent power/wavelength meter. The minimal wavelength step is 0.001 nm, which corresponds to 125 MHz or 0.125 GHz, which is 10 times more precise than standard optical spectrum analyzer.
Measurements of amplitude-frequency transmission characteristics of different optical components (isolators, attenuators, circulators, filters, etc.) in a wide wavelength (1470 nm to 1570 nm) range with the precision of 0.001nm (125 MHz) and wide optical power (-90 dBm to +10 dBm) range.
High measurements precision – 0.001 nm, which is 10 times higher than standard optical spectrum analyzer; simple and universal measurements scheme; wide wavelength and optical power range; possible to use different optical plugs and free-space optics (fiber-lens-lens-fiber).
