The Exfo IQS-2150 Optical Light Source is a modular precision instrument for testing and characterizing fiber optic components and systems across telecommunications, data center, and research environments. It delivers stable, accurate optical signals using single- or dual-wavelength LED and DFB laser emitters configured for singlemode and multimode fiber types. Steady drive circuitry maximizes output power stability while precision optical coupling ensures low-loss, narrow-beam efficiency.
