Abstract:
1. A fiber optic system, comprising: a primary transmission path provided from a source; a backup transmission path provided from the source; a branch unit provided at a meeting point of the primary and backup transmission paths, the branch unit including: wherein, in a first mode of operation, the switch set to provide the primary signal to the output port of the switch, wherein, in a second mode of operation, the switch is set to provide the backup signal to the output port of the switch, wherein the processor instructs the switch to operate in one of the first mode of operation and the second mode of operation, based on the received information, a splitter provided at a second end of a main optical path, a first end of the main optical path corresponding to the output port of the switch, wherein, at the second end, the splitter splits a signal traveling on the main optical path onto a first branch path that is coupled to a destination, and a second branch path that is coupled to the destination, and wherein the destination inputs signals from one of the first and second branch paths.
