As Gigabit Ethernet becomes a reality, installers must learn about the “active” side of testing. Although not often acknowledged, there is a great divide in the world of network testing. On one side ...

The use of passive devices in low-voltage applications is becoming increasingly common. For example, laptops and cell phones require batteries with ultra low internal (ionic) resistance. So ...

While temperature-sensing, passive RFID-based solutions have been available for several years, adoption is often limited or delayed due to the cost of piloting the technology. Many companies have a ...

The Yokogawa AQ7275 PON-OTDR is a passive optical network (PON) version of Yokogawa’s highly successful AQ7275 portable optical time-domain reflectometer (OTDR). The instrument is designed to overcome ...

A shipping container that can test passive cooling systems could help researchers and builders find carbon-free ways to keep people cool in extreme temperatures. Researchers created the 60 square-foot ...

A global energy company is testing a newly released passive sensor tag that measures temperature levels—and, in one version, mechanical strain—then transmits that data to nearby readers via UHF RFID.
