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 ...

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 ...

A new year means a new start, and for some pieces of media, it means entering the public domain. In 2024, one of the most famous additions to the public domain was the first iteration of Mickey Mouse, ...

We have noticed that sometimes, Windows fails to resolve the domain name when one tries to ping it or do nslookup. Sometimes, when trying to run the nslookup command, they encounter this; however, on ...

The end of daylight saving time will be here before you know it, meaning the majority of Americans will gain an extra hour of sleep in a few months as the clocks fall back. Daylight saving time began ...

Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level. When you purchase through ...

Daylight saving time began this year in the early hours of Sunday, March 10, 2024, giving us longer, sunnier evenings until Nov. 3. Here's what to know about how the time change works. How does ...

Longer days—kickstarted by an hour less of sleep—lie ahead for most of North America as the clocks “spring forward” this Sunday, March 10, marking the beginning of daylight saving time. The practice ...
