WebMar 14, 2024 · Beyond the Limitation of Pulse Width in Optical Time-domain Reflectometry. Hao Wu, Ming Tang. Optical time-domain reflectometry (OTDR) is the basis for distributed time-domain optical fiber sensing techniques. By injecting pulse light into an optical fiber, the distance information of an event can be obtained based on the time of light flight. WebThe critical pulse power, at which the performance of C-OTDR is degraded by the effect of optical nonlinear phenomena in a single-mode optical fiber, depends on the amplified optical pulse waveform and the pulse width. For a pulse width of 1 /spl mu/s or longer, the incident pulse power is limited by the effect of self-phase modulation (SPM).
