The JDS FITEL SB04-4B5-D2FP is a 2(1×2) fiber optic switch from the SB Series, enabling two independent 1×2 switching operations within a single unit. It employs expanded beam lens technology with processor-controlled stepper motor actuation to achieve precise optical channel alignment, minimal insertion loss, and excellent repeatability. The switch operates bidirectionally and accommodates both single-mode and multimode fiber configurations.
