The Optilab Handheld 2x1 Optical Switch module is a simple and reliable tool for engineering, laboratory, and production settings and field applications. It directs optical signals from one input into two outputs via a singlemode fiber pass. The switch is activated by a manual toggle switch mounted on the module. It can be powered by an internal 9 Volt DC battery or an AC adaptor. The switch features a latch design allowing a single battery will provide tens of thousands of operations.
