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.

Network elements such as digital crossconnects are provided with a 1:1 redundancy of, among other things, the switching matrix in order to maintain their functionality in the event of a hardware failure. Against disasters such as fires, explosions, or floods in which all equipment in a room is destroyed, the redundancy used in prior-art network elements can afford no protection.To remedy this, the two switching matrices (21, 22), which are present anyhow, are installed in separate rooms (31, 32), i.e., a single network element is divided between two rooms. To this end, the interface modules (23, 24) are divided into two groups, and each of the groups is assigned to a respective one of the switching matrices. A respective one of the switching matrices and a respective one of the groups of interface modules are arranged in, e.g., a cabinet or rack so as to form a unit, and the units are interconnected by simple internal links (34) such that both switching matrices (21, 22) are connected to all interface modules (23, 24).
