    Abstract: A method and system for protecting against communication loss or disruption in an optical network system includes a signal state detector, which can measure received optical signals and determine if their strength is sufficient to support reliable communications. If the signal state detector informs the control circuit that the received optical signal is too low to support communications with the data service hub (or if there is no signal at all, such as in a severance of an optical waveguide), then the control circuit can instruct the data switch to re-route communications from the primary communication path to a secondary or back up communication path. This switching or re-routing of communications from a primary communication path which is non-functional or inoperative to an operational and fully functional communication path (a back up or secondary communication path) can be completed in a very short time, such as within fifty milliseconds or less.
