摘要： The present invention is an apparatus and method that identifies and localizes fiber breaks or faults automatically, utilizing a fiber optic data transceiver that has μOTDR functionality. The transceiver of the present invention is a single wavelength bi-directional transceiver that during normal operation sends and receives optical data streams in the same wavelength window using any protocol and reports the distance to the fault or multiple faults nearly instantaneously when the transfer of data is disrupted, without the need to have fiber lines dedicated for this purpose or physically connect and reconnect each fiber line to check for faults and eliminates the need to map out the distance to the remote transceiver.

摘要： A monitoring and troubleshooting system to determine whether or not an antenna that is used for receiving wireless weak signals, like base station for cellular wireless communication, is operational. The antenna status condition is signaled over the Fiber Optic (FO) link without interfering the signal during normal operation. When a fault is detected the status at the FO receiver is determined. Then, an indication using special signaling allows a service technician to distinguish if the status fault is antenna failure or antenna disconnect. The present invention will also allow a service technician to determine if there is a FO link failure by use of light intensity monitoring. The present invention also includes a method of monitoring the status of a radio frequency antenna with the apparatus as discussed above.

摘要： A fiber optic transceiver adapted for use in an optical fiber data transmission system is capable of detecting reflection problems in fiber optic links and providing information related to the distance to the point of reflection. The fiber optic transceiver contains a fiber interface, a receiver, a transmitter, and a microcontroller. The microcontroller controls the transmitter to modulate the laser power to transmit impulse test data and the transceiver includes circuitry and microcode to detect reflection due to fiber connection problems. This enables trouble shooting during installation and/or reconfiguring the connection automatically, in response to a connection problem, and provides a physical layer link.
