The IQS-2400 features wavelength-tuning capabilities around each of the ITU-T grid wavelengths, dithering up to 300 kHz with a triangular or square waveform, and an output power reaching 13 dBm with a 10 dB attenuation range. DFB laser diode manufacturers have the option of providing their own DFBs.
Multifunctional flexibility to match your needs
The IQS-2400 WDM Laser Source can operate in four different modes: Normal, High-Wavelength Stability, Dithering, and On/Off. Normal mode provides access to total wavelength and power tuning ranges, maintaining full control of the output power (automatic power control). From a set point in wavelength and power levels, the High-Wavelength Stability mode provides finer wavelength and power tuning resolutions through laser temperature steps of 0.01 °C and laser current steps of 0.01 mA. This mode operates the laser at a constant current (automatic current control). Since the central wavelength may drift slightly (due to aging) in Normal mode, the High-Wavelength Stability mode allows for continuous access to long-term, high-accuracy wavelength set points.
The last two modes, On/Off and Dithering, provide modulation capabilities from 10 Hz to 300 kHz. On/Off mode ensures maximum optical extinction when activated, while Dithering mode adds a small waveform (triangular or square) to the CW signal, thus reducing the signal coherence length. In On/Off mode, several sources can be synchronized from an external TTL signal generator or from any module’s synchronization output. Therefore, each source can operate at a different frequency and amplitude or precisely in phase.
Versatile and reliable EDFA and WDM testing
Combine more than one modular IQS-2400 WDM Laser Source with an IQS-3150-B Variable Attenuator or IQS-3150-BI Variable Attenuator (with integrated power meter), an IQS-1700X Power Meter and an IQS-5240B Optical Spectrum Analyzer in an IQS-600 Integrated Qualification System. This setup enables precise, stable tones at every attenuation step throughout the complete WDM spectrum. Automatic tone balancing avoids the time-consuming and tedious manual adjustments that were once necessary to obtain a uniform input comb.
