Abstract:
1. A fiber optic transceiver and fault detection system having at least one data stream comprising: a. at least one optical fiber having a first end and a second end; b. at least one optical transmitter including a laser diode and a high speed laser diode driver coupled to the first end of said optical fiber; c. at least one optical receiver coupled to the second end of said optical fiber; d. a data stream; e. a means to separate an outgoing stream of data from an incoming stream of data; f. a means to transport the data stream bi-directionally over a single optical fiber; g. a means to transmit data includes impedance matching between the laser diode and the laser diode driver; h. a generator means to transmit a high power pulse to the laser diode including impedance matching between the laser diode and a high power pulse generator means; i. the means to transmit the high power pulse to the laser diode is decoupled from the means to transmit data; j. a means to receive an echo of the high power pulse includes a differential amplifier and a differential noise filter; k. a means to measure the time between sending the high power pulse and the time to receive the echo of the high power pulse; and l. at least one optical element, said at least one optical element used for both data transmission and optical time domain measurements of a reflection in the optical fiber; m. whereby the existence and the location of a fault in an optical fiber is detected.
