Benefits:
High optical output power offers the flexibility in test environment and enables test and characterization of nonlinear effects which the customer could not do so far.
The precise tunability around IT-grid center wavelength gives you the flexibility to match test setups to latest requirements of the DWDM-system. The fine-tuning allows to shift the center wavelength from one DWDM transmission channel to the adjacent channel in dense WDM systems.
The coherence control allows to change the linewidth of the laser to avoid problems with stimulated Brillioun scattering, and effects generated by unwanted cavities.
The built-in digital modulation enables applications like time-domain extinction testing of EDFA noise figure.
The built-in isolator ensures laser stability, even when reflections are present in the optical path.
