System Overview
System Overview
The IQS-12004B DWDM Passive Component Test System provides spectral
insertion loss (IL), polarization-dependent loss (PDL), and optical return
loss (ORL) measurements with high resolution and accuracy.
The DWDM Passive Component Test System sweeps a very-low-noise
tunable laser source across the spectral band of interest (C-band or
C+L-band). While the source is sweeping, synchronized measurements
from the Wavelength Reference Module (WRM) and the measurement
power meters are acquired into the system software. At the end of the
sweep, advanced signal processing is applied to the data, resulting in
accurate IL, PDL, and ORL data.
This configuration ensures quick testing time that is practically
independent of the number of device ports (there is a nominal data
transfer and analysis penalty per channel). Because of the low source
spontaneous emissions (SSE) of the IQS-2600B/IQS-2600CT Tunable Laser
Source, a dynamic range of 60 dB is easily attained. The wavelength
reference module ensures wavelength and loss accuracy by providing
a fast and continuous wavelength and power reference throughout the
sweep.
The numerous software features are explained later in this user guide.
