    Abstract: A method and device are disclosed for monitoring communication activity within an optical communications network. The device includes a pair of optical components for tapping optical signals transported across a fiber optic line in the optical communications network. At least one optical performance monitor (OPM) receives tapped signals from the pair of optical components. An optical switch, controlled by the OPM, selectively provides to the at least one OPM tapped signals corresponding to optical signals traveling on the fiber optic line in a first direction. The OPM measures the various signal characteristics of the tapped signals when the optical switch is opened and closed, and determines the direction of travel of optical signals on the first optic line based upon the measured signal characteristics.

    Abstract: A bi-directional fiber optic jumper that connects two fiber optic system common wavelength fibers is disclosed. The retraction of the jumper exposes fiber connections and enables a system reconfiguration such as adding or dropping of common wavelengths into open fiber connections. A magnet is provided in the chassis of the jumper to engage a magneto-resistive device, such as a Hall effect sensor feature, that is contained on an optical add/drop device product chassis. The Hall effect sensor facilitates monitoring of insertion or withdrawal of the fiber channel jumper from the optical add/drop device.
