WDM Laser Source
Main Features
The IQS-2400 WDM Laser Source is a DFB laser source configured at a
wavelength set at the time of purchase. However, you can adjust this
wavelength within a ± 1 nm tuning range around the ITU-T wavelengths.
This DFB laser source integrates an internal attenuation so you can vary the
output power. The built-in optical isolator of the DFB laser increases power
stability. All models, except the IQS-2402, can also come equipped with a
built-in polarization-maintaining fiber (PMF) output.
The power and wavelength of each DFB laser are calibrated using a
wavelength meter and a four-channel power meter traceable to NIST
standards (for power) or to natural physical constants (for wavelengths).
This calibration method ensures a fully referenced and automated
calibration of the DFB’s internal temperature and laser current to obtain a
precise central wavelength at any power level.
