The JDS Uniphase SB Series is a programmable optical fiber switch engineered for telecommunications, manufacturing, and test environments requiring precise optical channel alignment. Built on expanded beam lens technology, the series delivers stable, high-performance switching across both single-mode and multimode fiber types. A precision stepper motor and temperature-controlled mechanism ensure repeatable channel positioning across a broad optical spectrum.
