What is Single Pair Ethernet (SPE) and why is it so important for the Industrial Internet of Things (IIoT)? SPE is based on a two-wire cabling protocol offering secure communication over longer distances and with a smaller footprint. These features are central to the question of why SPE is needed. As more and more devices in commercial and industrial applications become “connected”, there are increased demands on space both inside the devices and in the cable ducts that connected them together. And while WiFi has its uses in these environments; it does not offer the security or reliability of a wired communications network.
A new standard for single pair Ethernet (SPE) is gathering speed with multiple companies joining the SPE industrial partner network to avoid making the same mistakes as the past with proprietary connector systems.
Twenty years ago, first-generation wireless wasn’t considered a necessity. But the technology has evolved to a point where a robust wireless network is mandatory in many building locations, and it’s as crucial to a healthy enterprise as computers and smartphones. Organizations in a variety of sectors have seen a dramatic increase in the network speeds required to operate effectively. These organizations include office environments, manufacturing facilities, schools and campuses, and hospitals.
Today, buildings are required to deliver secure technology services and engaging, productive, personalized experiences to occupants, all while making sure the facility is efficient, reduces costs, and has a lower environmental impact. Going beyond that baseline, a smart building uses an integrated set of technology, systems, and infrastructure to optimize building performance and occupant experience. The key concept is “integrated,” as it applies to technology, systems, and infrastructure.
The novel COVID-19 pandemic has significantly impacted the built environment as a whole, causing great disruption to how buildings previously managed their systems and operations. This new normal will cause building managers to follow stricter guidelines and safety measures and show occupants that safety and protection is of the utmost importance. In addition to frequent cleaning and disinfection, building managers must act as quickly and efficiently as possible to achieve a particular level of indoor air quality (IAQ).
Technology can help restore confidence in returning to large venues by monitoring visitor temperatures and movements. Solutions to COVID-19 monitoring and compliance require an ecosystem of technology manufacturers, working together to develop solutions for venues of all types. There are four key technologies that provide solutions: Network Connectivity, Location & Analytic Systems, Sensors and Software applications.
With OM4 at a premium over OM3, many data centers and LANs not requiring the extra distance afforded by OM4 continue to deploy OM3 multimode fiber cabling, and it remains more widely deployed for that reason. And while the two fiber types can be mixed due to the same core size, there are some considerations in general when it comes to mixing multimode fiber types.
Furukawa Electric Co has conducted an experiment in its Mie, Japan facility to demonstrate the installation of a 6912-fiber optical cable with an outer diameter of 1.14 inches (29 mm) in a 696 foot (200m) long conduit with three 90 degree curves and an inner diameter of 32mm. The conduit used was a standard product installed in conventional data center campuses. Engineers confirmed a maximum pulling tension of 84 pounds (372N), well below the maximum pulling tension of 600 pounds (2700N) specified for the cable.
China might be crushing it in 5G, but the rapid rollout is also widening its digital divide. According to the latest MIIT figures, Chinese operators have deployed 480,000 5G base stations – that’s at least twice as much as the rest of the world combined.
But these base stations serve a tiny proportion of potential users. Shenzhen has 45,000, Beijing 44,000 and Shanghai 56,000. In other words, 30% of China’s base station population serves 4% of its human population.
Single Pair Ethernet is poised to enable a new class of low power devices that will facilitate networking and powering the billions of endpoint sensors forecasted by the year 2022. The SPE standards provide endpoint sensors with a unifying communication protocol and a common networking infrastructure extending the cost-effectiveness and plug-and-play simplicity of Ethernet. Endpoint sensor technology and use cases are evolving rapidly in industrial/process, building automation, data centers as well as to support “Intelligent Building” technologies; IoT infrastructure. TIA’s TR-42 committee is developing single pair telecommunication standards for single pair infrastructure topologies, cabling, and field testing.
