Advanced Testing for Wavelength Routing & Tunable Filters
The rapid evolution of wavelength-division multiplexing (WDM) and dynamic optical networks demands highly accurate testing of wavelength routing components and tunable optical filters. At Fiber Optical Test, we deliver cutting-edge Wavelength Routing and Tunable Filter Testing systems engineered to ensure optimal spectral alignment, channel integrity, and wavelength agility. These systems are essential for validating Reconfigurable Optical Add-Drop Multiplexers (ROADMs), wavelength-selective switches, and tunable transceivers. From metro and long-haul networks to flexible grid DWDM systems, our solutions support scalable deployment and continuous optimization. Based in Grand Chute, WI, Fiber Optical Test has quickly earned its reputation as a leading innovator in fiber optic testing, serving a growing network of B2B clients across North America. With deep technical expertise, we help our customers reduce errors, speed up deployment, and future-proof their optical infrastructure.
