摘要： An apparatus includes an optical amplifier configured to receive an input opticalsignal and generate an amplified output optical signal. The optical amplifier includesmultiple amplifier stages including at least a first amplifier stage and a secondamplifier stage. The apparatus also includes a gain clamp configured to accumulateoptical power from the first amplifier stage after an optical power level of the input optical signal drops and provide a first portion of the accumulated optical power to thefirst amplifier stage to clamp a gain applied by the first amplifier stage. The gainclamp is also configured to provide a second portion of the accumulated optical powerto the second amplifier stage to adjust a gain applied by the second amplifier stage.The second amplifier stage is configured to amplify the second portion of the accumulated optical power.

摘要： An apparatus (100) includes multiple ports (102-108) configured to be coupled to multiple optical fibers (110-112) and to transmit first optical signals and receive second optical signals over the optical fibers (110-112). The apparatus also includes a signal source (118) configured to generate a first additional optical signal for inclusion with the first optical signals. The apparatus further includes a signal detector (120) configured to detect a second additional optical signal included with the second optical signals. In addition, the apparatus (100) includes a switch (122) configured to selectively couple the signal source (118) to one of the ports (102, 106). The switch (122) is configured to couple the signal source (118) to different ones of the ports (102, 106) in different configurations of the switch (122).

摘要： A method and apparatus for time domain reflectometry. The method comprises: providing a source optical signal having a first frequency (f 1 ); encoding and transmitting a first Golay code test signal and then a second complementary Golay code test signal along an optical fibre, wherein encoding the first and second Golay code test signals comprises using a frequency modulator (203) on a first portion of the source optical signal such that one of the states of the Golay code is encoded as the first frequency (f 1 ), and another state of the Golay code is encoded as a second frequency (f 2 ), the second frequency (f 2 ) being produced by shifting the frequency of the optical signal from the first frequency (f 1 ) to the second frequency (f 2 ); detecting reflections of the first and second Golay code test signals that are mixed with a second portion of the source optical signal at a heterodyne detector (206) to produce a first and second detected reflection signal, respectively corresponding with reflections of the first and second Golay code test signals; processing data (r A (t), r B (t)) derived from the first and second detected reflection signal to approximate reflections (h(t)) from the optical fibre in response to a delta function test signal.
