Center Off 1x2 Fiber Optic Switch

Overview

The center off 1x2 optical switch is a 1x2 configuration with 3 fibers and 3 states. Similar to a regular 1x2, it has an additional "center off" state with no optical connections when the electrical drive is off.

Optical and Electrical Connectivity

The following diagrams show the optical connections for the 3 states. The numbers identify the fiber endpoints. In state 1, with power applied, there is an optical path between fibers 1 and 3. In state 2, with polarity reversed, fibers 1 and 2 are connected. With no power applied, no fibers are connected.
