Dual 1x2 Fiber Optic Switch
The dual 1x2 optical switch is equivalent to two single 1x2 fiber optic switches
in one switch that change state together (they cannot be switched independently).
A lower cost custom dual 1x2 switch has an extra optical path in state 1. This extra path is often not an issue and may even be beneficial as a loopback.
The following diagrams show the optical connections for the 2 states. The numbers
identify the fiber endpoints. If looking at it as 2 single 1x2s, fibers 1, 6 and
5 make up one single 1x2 while fibers 4, 2, and 3 make up the other.
