A new scheme of optical pulse compression reflectometry based on amplified heterodyne detection is proposed to enlarge the measurement range. 58 km measurement range with 10 cm spatial resolution is experimentally demonstrated.
We propose a novel scheme of optical pulse compression reflectometry (OPCR) based on double sideband modulation (DSBM). Owing to the use of DSBM in the novel scheme, the cost-effectiveness and the stability of the OPCR are essentially enhanced. The working principle and the theoretical analysis are demonstrated. Experiment is conducted to verify that the performance of the DSBM-based OPCR is comparable...
A new scheme based on pulsed linear frequency modulation is proposed to improve the stability and spatial resolution of optical pulse compression reflectometry. 10 cm spatial resolution over 5.4 km measurement range is experimentally demonstrated.
We present a reflective-type delay line using side-coupled integrated spaced sequence of resonators (SCISSOR) terminated with a Sagnac loop reflector. With 13 microrings, group delay of ∼150 ps is achieved with 170 GHz bandwidth.
