FIBERFUTURE optical attenuator is a passive device that reduces the power level of an optical signal, commonly used in single-mode long-haul applications to prevent receiver overload. Widely applicable in CWDM/DWDM, CATV systems, data centers, and test equipment, they ensure signal stability. The in-line VOA includes a dual fiber collimator and an ND filter for dynamic power control, making it ideal for adjusting signal levels in optical communications. The collimator VOA is essential for testing optical components and systems.
