Fiber components is a large category that includes collimators, polarization controllers, couplers, WDMs, circulators, attenuators, and all of the tools and supplies needed to connectorize, inspect, and clean fiber and fiber components. The Test & Measurement category includes the rack-based lasers, TEC controllers, and current controllers that are frequently used in fiber-based experiments and test systems. In addition, optical switches, modulators, and polarization control and measurement systems are found in the Test & Measurement category.
