Abstract
A reversible optical switch which allows a node to be inserted into or removed from a fiber optic network is disclosed. In a first state, the switch of the present invention provides a path between an incoming optical fiber and the node receiver and a path between the node transmitter and an outgoing optical fiber. In a second state, the switch connects the incoming and outgoing fibers, so that the network bypasses the node and connects the transmitter and receiver so that the bypassed node can be tested.
