Seifert thermoelectric enclosure coolers from AutomationDirect beat the heat

Automation-Direct has added new high-quality and efficient stainless steel Seifert 340 BTU/H thermoelectric coolers with 120-V and 230-V power options. Thermoelectric coolers from Seifert use the Peltier Effect to create a temperature difference between the internal and ambient heat sinks, making internal air cooler while dissipating heat into the external environment. Fans assist the convective heat transfer from the heat sinks, which are optimized for maximum flow.

Free-Core vs. Spring-Loaded LVDT position sensors

Linear Variable Differential Transformers are electro-mechanical devices used in many industrial applications to measure the displacement or position of an object. They convert the linear position or motion of a measured object into an electrical output that is displayed on a local readout or input into a programmable logic controller as part of an automated process control system. LVDTs come in two core configurations -- free-core and spring-loaded -- but do you know what the differences are?

Aston University researchers break world record again for data transmission speed

Researchers at Aston University in Birmingham, England, are part of a team that has sent data at a record rate of 402 terabits per second (Tbps) using commercially available optical fiber. This new feat beats their previous record, announced in March 2024, of 301 Tbps -- or 301,000,000 megabits per second (Mbps) -- using a single, standard optical fiber.

If compared to the internet connection speed recommendations of Netflix of 3 Mbps or higher for watching a HD movie, this speed is over 100 million times faster. The speed was achieved by using a wider spectrum, using six bands rather than the previous four, which increased capacity for data sharing. Normally, just one or two bands are used in optical fiber data transmission.

The international research team included Professor Wladek Forysiak and Dr. Ian Philips, who are members of the University's Aston Institute of Photonic Technologies (AIPT). Led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT), which is based in Tokyo, Japan, the team also included Nokia Bell labs in the United States.

Together, the international team achieved the record by constructing the first optical transmission system covering six wavelength bands (O,E,S,C,L, and U) used in fiber optical communication. Aston University contributed specifically by building a set of U-band Raman amplifiers, the longest part of the combined wavelength spectrum, where conventional doped fiber amplifiers are not presently available from commercial sources.

Optical fibers are small, tubular strands of glass that pass information using light, unlike regular copper cables that can't carry data at such speeds.

As well as increasing capacity by approximately a third, the technique uses so-called "standard fiber" that is already deployed in huge quantities worldwide, so there would be no need to install new, special cables if this technology were implemented in real-world systems.

As demand for data from business and individuals increases, this new discovery could help keep broadband prices stable despite an improvement in capacity and speed.

Aston University's Philips said, "This finding could help increase capacity on a single fiber so the world would have a higher-performing system. The newly developed technology is expected to make a significant contribution to expand the communication capacity of the optical communication infrastructure as future data services rapidly increase demand."

Forysiak added, "This is a 'hero experiment' made possible by a multi-national team effort and very recent technical advances in telecommunications research laboratories from across the world."

The results of the experiment were accepted as a post-deadline paper at the 47th International Conference on Optical Fiber Communications (OFC 2024) in the United States on March 28, 2024.
