The IQ-2400 emulates ITU-T channels in dense WDM applications such as multiwavelength network simulation, simultaneous multiple
inputs for EDFA characterization and insertion loss measurement of DWDM passive components. This source is ideal for the production
environment offering unmatched, long-term wavelength stability. The ±0.01 nm absolute accuracy enables the IQ-2400 WDM Laser Source
to replace a wavelength measurement instrument when testing components or systems. The IQ-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.

    The IQ-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, High-Wavelength Stability mode provides finer wavelength and power tuning resolutions
through laser temperature steps of 0.01oC 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, 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.
