This unit
The ILX Lightwave FOS-79800D is a WDM DFB fiber optic source module engineered for precision optical testing in research, development, and production environments. It operates as a plug-in module within the FOM-7900B Fiber Optic System Mainframe, delivering high-stability, tunable laser output across C-band and L-band wavelengths. The module provides excellent power stability, precise wavelength control, and flexible modulation capabilities, making it ideal for EDFA, SOA, and fiber optic component characterization in WDM and CWDM test scenarios.
