Abstract: High-resolution photon-counting optical time-domain reflectometry (PC-OTDR) is crucial for the development of fiber-optic sensing and network diagnostics, allowing accurate fault location ...
Abstract: A novel Brillouin optical time-domain reflectometer using an adaptive frequency analysis (AFA) algorithm enhances spatial resolution by 2.5 times at 10 MHz frequency resolution compared to ...
A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...

How optical clocks are redefining time and physics
Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block, the ...
In this look at transmission line theory, we will assume an RG-58 type of coaxial cable which has a characteristic impedance of 50 Ω. Where we let C stand for the capacitance per unit length, 30 pF ...
Coherent Corp., a leader in photonics, has introduced a new embedded Optical Time Domain Reflectometer (eOTDR) in a QSFP package designed for advanced fiber network diagnostics. This device boasts a ...
