Securing smart homes and smart buildings from cybersecurity risks becomes more relevant than ever in the light of the COVID-19 pandemic crisis. ENISA presents some fundamental measures for securing smart devices.
The Ethernet Alliance’s recent Power over Ethernet (PoE) product certification survey reveals some 78 percent of respondents experienced difficulties with PoE deployments — but that 72 percent expect noticeable improvement with products certified through the Ethernet Alliance’s PoE Certification Program. Further findings from the survey are available in a newly released infographic, available at: https://bit.ly/EA-PoEInfographic2020.
With the entire world currently under “stay at home” orders due to the coronavirus pandemic, everyone who is classified with “non-essential” jobs is now working from their homes or not working at all. In doing so, everyone is realizing the importance of the “4th Utility” — the Internet. Just like flipping on a light switch or turning a faucet on for water, network connectivity is an expected deliverable.
Increase in the demand for reliable structural health information led to the development of Structural Health Monitoring (SHM). With the maturity of the IoT, one of the recent challenges in the structural engineering community is development of the IoT SHM systems that can provide a promising solution for rapid, accurate, and low-cost SHM systems.
Multimode Fiber is still the front runner in modern Enterprise Data Centers as it provides a low-cost way to transport high data rates over relatively shorter or smaller distances. MMF has evolved from being optimized for multi-megabit-per-second transmission using LED light sources to being optimized for supporting multi gigabit transmission using 850m VCSEL (Vertical Cavity Surface Emitting Laser), which tend to be more affordable than their single mode counterparts.
Pluggable coherent optics are now being developed for 400G applications with two distinct streams emerging. One is high performance CFP2 based for 1000+km reach and multi-service applications and the other is QSFP-DD ZR (and perhaps OSFP) for DCI and metro Ethernet applications. Both streams present new challenges for test and measurement, not just to meet the demanding technical specifications but also to ensure pain-free integration and deployment in an open ecosystem.
Join Corning for a complimentary six-part Live Webinar Series on “Staying Connected with the Data Center.” This series aims to provide quality training in the latest applications and solutions in the Data Center world, while also sharing best practices to make better informed decisions on meeting bandwidth requirements both now and in the future. Topics include scaling from 10G to 400G, the technology roadmap for optical transceivers, and what considerations data center infrastructure professionals should keep in mind to enable this evolution.
Read the next issue of the FOA’s newsletter online. While the photo above doesn’t show “social distancing”, FOA has all its certification tests available online, both for use by our schools and by our direct “Work to Cert” applicants. All tests require a proctor to oversee the applicant taking the exam. In this time of social distancing, getting a proctor can be difficult, so FOA now has procedures for online proctors and administering the exam. Contact the FOA for more information.
Fiber Optic Connectors need to be pristine when they are connected for several reasons. First, dirty or damaged connectors are the number one cause of network outages. Second, if a dirty or damaged connector is plugged into another connector, your problem just doubled. Lastly, if test equipment, like an OTDR, or a network element, such as a receiver, is damaged it can cost hundreds or thousands of dollars to repair or replace them.
Bend-insensitive fibers significantly reduce #microbend and #macrobend losses across the entire wavelength spectrum used by current and future PON. There are two types of bend-insensitivity: Millimetre-range macrobend-insensitivity and Micrometre-range microbend-insensitivity. While #BendBrightXS fibres were initially developed with macrobend-insensitivity in mind, they also outperform all other existing fibre types for microbend-insensitivity. BendBrightXS fibres support the full use of transmission bands, covering the entire wavelength spectrum: from 1260 nm to 1625 nm for data transmission, and up to 1675 nm for network monitoring.
