Advanced Testing for Wavelength Routing & Tunable Filters

Fiber Optical Test delivers cutting-edge Wavelength Routing and Tunable Filter Testing systems engineered to ensure optimal spectral alignment, channel integrity, and wavelength agility.

Overview

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.

Case Studies

U.S. ROADM Validation for National Fiber Network

A leading telecom operator in the Midwest U.S. implemented Fiber Optical Test’s tunable filter testing suite to validate a 200-node ROADM network. Our systems detected spectral inconsistencies across suppliers, reducing post-deployment tuning time by over 60%.

U.S. Optical Device Manufacturer Production QA

An optical filter OEM integrated our automated wavelength routing testbed into its manufacturing line. This resulted in a 35% increase in throughput and a 25% drop in return rate due to improved alignment precision.

Canadian Academic Lab Developing Next-Gen Filters

A Canadian university lab partnered with Fiber Optical Test to benchmark novel tunable filter designs. With our high-resolution test systems, researchers achieved sub-10 pm spectral stability, accelerating their publication timeline and prototype readiness.
