The Agilent 8166xA Distributed Feedback Laser Sources are part of the Agilent Lightwave Solution Platform, and best suited for amplifier test and DWDM system test applications. Agilent covers the C- and L-Band with its family of Distributed Feedback (DFB) laser source modules 81662A (10dBm) and 81663A (13dBm).

Features:

• High optical output power: +13 dBm
• Wavelength Stability: +/- 0.002nm
• Fine-tuning range: +/- 850pm
• Power stability: 0.003dB
• Built-in coherence control
• Built-in digital modulation
• Built-in isolator

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.
