  • Publication number: 20140016930
    Abstract: A tracking system includes a tracking arrangement including a processor, memory, and at least a first interface port; and one or more optical modules. Each optical module includes a housing having at least one input port, at least a first output port, and at least a first monitoring port. An optical power splitter arrangement and an optical receiver are disposed within the housing. The splitter arrangement splits optical signals received at the input port onto one or more output lines and one or more monitoring lines. The output lines are routed to the output ports and the monitoring lines are routed to the optical receiver. The optical receiver measures the power of optical signals received from the first monitoring line and provides a measurement signal to the first monitoring port of the housing.
