Manufacturing test automation is critical to reducing product costs and optical switches are at the heart of any automated test system. The VIAVI mOSW-C1 Optical Switch Module and mISW Optical Switch Tray are built on the industry-leading, fourth-generation instrumentation class of VIAVI optical switch technology. With more than 30 years of leadership in optical switching across network, monitoring, and manufacturing applications, the mOSW-C1/mISW-C1 represents a new milestone for performance and reliability with the industry-s smallest footprint.
