Abstract
Embodiments of the invention include an active optical cable and method for controlling the operation of the active optical cable based on the detection of signal loss, e.g., due to fiber breakage, within the active optical cable. The active optical cable includes first and second optical transceivers, each with an open fiber control module coupled between the transmission side and the receiver side of the respective optical transceiver. The transmission side of each optical transceiver is coupled to the receiver side of the other optical transceiver via a plurality of transmission channels, such as a plurality of optical fibers. Each open fiber control module is configured to detect an optical power level of an optical signal received by the receiver side of the optical transceiver within which the open fiber control module resides and, based on such detection, control the operation of the corresponding transmission side of the optical transceiver.
