The IQS-12004B DWDM Passive Component Test System is an innovative approach to DWDM component characterization. The system sweeps a very-low-noise tunable laser source across the spectral band of the device under test (DUT), and simultaneously measures power on multiple channels, thus providing a quick testing time that is practically independent of the number of device ports. Because of the low source spontaneous emissions (SSE) of the IQS-2600 and the IQS-2600B Tunable Laser Source, a dynamic range of 60 dB, or more, is easily attained. The wavelength reference module ensures accuracy by providing a fast and continuous wavelength reference across the sweep range.
