Introduction
The IQ-2600B is a tunable laser source that will address the testing
requirements for dense WDM component testing in C- and L-bands. The
60 dB spontaneous noise suppression ratio provides a better dynamic
range than with a traditional external cavity laser, thus allowing you to
measure crosstalk at the higher level required for passive component
testing. The source is always on when scanning, providing excellent
stability throughout the test session. The IQ-2600B’s linear and fast sweep
will enable a simple and efficient integration in most test system
architectures based on tunable lasers and power meters or optical
spectrum analyzers.
The IQ-2600B has been designed to test passive components. Its
coherence length is suited for detecting parasitic etalon or other
interference effect inside components. This medium coherence also
avoids problems such as connector-induced interference, which is
common when using high-coherence external cavity lasers. The
IQ-2600B’s relative immunity to vibration makes it perfect for production
testing, product qualification, and R&D use.
Main applications include the complete characterization of filters,
multiplexers, Bragg gratings, and other DWDM components. For EDFA
testing, use the IQ-2600B to check wavelength-dependent gain, noise
contribution, and saturation properties. It is also very useful for
determining the spectral sensitivity of receivers and detectors. The
IQ-2600B can also be controlled with GPIB or RS-232 interfaces.
