Product Description:
The Agilent HP 81662A distributed feedback laser source is part of the Agilent lightwave solution platform, which is most suitable for amplifier testing and DWDM system testing applications. Agilent's distributed feedback (DFB) laser source module series cover C and L bands, including 81662A (10dBm) and 81663A (13dBm).

Benefits:
-
The high optical output power provides flexibility in the test environment and can test and characterize non-linear effects that customers cannot currently perform.
-
The precise tunability around the center wavelength of the IT grid gives you the flexibility to match the test setup to the latest requirements of the DWDM system. Fine tuning allows the center wavelength to be transferred from a DWDM transmission channel to an adjacent channel in a dense WDM system.
-
Coherent control allows the linewidth of the laser to be changed to avoid the problem of stimulated Brillouin scattering and the effects of unwanted cavities.
-
Built-in digital modulation supports applications such as time-domain extinction testing of EDFA noise figure.
-
The built-in isolator ensures laser stability, even when there are reflections in the optical path.
