Abstract
Optical protection devices are provided for protecting client equipment in an optical communication system. According to one implementation, a protection device includes a passive optical coupler configured to combine optical signals from a plurality of input paths, where the passive optical coupler is further configured to provide the output signals along an optical output path. The exemplary protection device further includes one or more interrupters configured to allow at most one input from a plurality of optical inputs via the plurality of input paths to be provided to the passive optical coupler at one time.
