Allied Ask the Expert: How Single Pair Ethernet Enables a Future of Innovation in IIoT

SPE technology is designed to connect multiple devices and/or machines to a network and eliminate the need for “translation,” which previously would occur within the gateways. SPE enables full, real-time communication from the sensor to the cloud in a native language without losing information. The technology not only simplifies machine connectivity and data transmission but, in a broader view, facilitates an open ecosystem, with real-time and high-speed communication in a much more cost-effective way.

400G in the data center: options for optical transceivers – DCD

For cloud-scale data centers, their ability to adapt and survive is tested every year as increasing demands for bandwidth, capacity and lower latency fuel migration to faster network speeds. During the past several years, we’ve seen link speeds throughout the data center increase from 25G/100G to 100G/400G. Every leap to a higher speed is followed by a brief plateau before data center managers need to prepare for the next jump.

Currently, data centers are looking to make the jump to 400G. A key consideration is which optical technology is best. Here, we break down some of the considerations and options.

Really Fast Optical Tech Shipments To Triple in 2021, Dell’Oro Predicts

A new wave of high-speed coherent optical components are expected gain widespread adoption in 2021, according to Dell’Oro analyst Jimmy Yu.

While vendors like Nokia, Ciena, and Infinera have been teasing faster and faster optics for years, Yu noted in a blog post that the optical transport market is a research and development heavy industry, with multi-year product cycles. “Grand ideas and proof of concepts announced years ago steadily build toward commercialization and main stream adoption over the course of a few years,” he wrote.

Yu said several long-hyped optical technologies, including those offering higher line rates up to 800 Gb/s, are likely reach the market in 2021.

Environment and technology: our digital carbon footprint

Computers, electronic devices and digital infrastructures are consuming ever-increasing amounts of electricity. This is confirmed by Milena Gabanelli who, during her DataRoom on Corriere della Sera, reports interesting data on the harmful emissions produced by the technology and their use. In 2008, for example, digital technologies used in the transmission, reception and processing of data and information (ICT) contributed 2% to global CO2e emissions; in 2020 they reached 3.7% and will reach 8.5% in 2025, the equivalent of the emissions of all light vehicles in circulation.

Multitenant data centers are key to managing data without breaking the bank | Optical Communications | Corning

A multitenant data center (MTDC), also known as a colocation data center, is a facility where organizations can rent space to host their data. MTDCs provide the space and networking equipment to connect an organization to service providers at a minimal cost. Businesses can rent to meet varying needs—from a server rack to a complete purpose-built module. The scalability of usage provides the business benefits of a data center without the high price.
