OPTICAL TIME DOMAIN REFLECTOMETER WITH HIGH RESOLUTION AND HIGH SENSITIVITY
摘要
<p>An optical time domain reflectometer (OTDR) system with an integrated high speed optical modulator is capable of operating at a speed similar to the OTDR pulse width to improve the measurement resolution and reduce the time required to acquire a high dynamic range OTDR measurement over existing approaches. ASICs can be used to control the modulator and generation of pulses. The high-speed optical modulator enables high resolution single-photon OTDR measurement by blocking out all return light except from the region of fiber under examination.</p>
