What if you could double the bandwidth of your outside plant fiber optic network easily, or even multiply the bandwidth by 10, 20 or more? In high-speed links, it’s a common practice and accomplished using wavelength division multiplexing (WDM).

Nokia unveils 100G PON for fiber broadband in U.S.
Nokia’s research arm, Nokia Bell Labs, presented what the company billed as the first 100Gb/second broadband technology in the U.S. at last month’s Fiber Connect 2022 (June 12-15) conference in Nashville, Tenn.
The technology prototype presented delivers 100Gb/s downstream speeds on a single PON wavelength, avoiding the need to combine multiple wavelengths carrying lower speeds, noted the company.
ICT industry not dealing with The Great Resignation but rather, The Great Retirement
Overall compensation for ICT professionals was down this past year, in no small part because the most-experienced workers are leaving the workforce. Three factors that depressed compensation in 2021: 1) inflation was considered transitory until late 2021 and did not show up in last year’s paychecks; 2) overtime and bonus pay reduced sharply from 2020; and 3) more-experienced and higher-paid workers left the workforce, driving down the mean compensation among the workforce as a whole. On the bright side, women represented 9% of participants, which is the highest percentage in the survey’s four years and up from 4% a year ago.
Why smart building networks also need resiliency
Without the right plan, integrating smart technologies into a new or existing building can be a major challenge. At its core, a building’s consolidated IT/OT network serves as the foundation on which all smart technologies are layered. Because of this, resiliency must be designed and managed from the network up.
Standards for intelligent building communications systems emphasize performance and flexibility
While several aspects of smart building operation may be regarded like the Wild West, with rules and standards undefined, multiple generations of standards already exist for the communications cabling systems serving these properties.
Single Pair Ethernet on its way into the smart building
SPE offers the security that many purpose-built systems lack, and is optimized to reduce labor and materials costs in a network’s physical layer.
Single Pair Ethernet: The Evolution of Automation Device Communications
This presentation, from the Fall 2022 BICSI Conference, discusses why SPE technology is important to Building Automation Systems, provides an overview of standards and applications, and an update on SPE development.
How Digital Twins Technology Enables Smart Buildings, Smart Cities – Facilities Management Insights
Digital twins, paired with ubiquitous broadband, offers the building sector the promise of reducing both cost and greenhouse gas emissions while improving operational efficiency and transparency.
Why Manufacturer Cable Warranties are So Important
Looking at copper and fiber cabling plants, one of the best ways to gain more value is to ensure it comes with a long-term replacement warranty directly from the cable manufacturer. Obtaining a full manufacturer’s warranty can only be accomplished through cable certification testing. Without proving passing certification test results, your cabling will not be fully covered by most manufacturer warranties. In this article, we’re going to explore what a cable manufacturing warranty is, why you want one and how to best obtain a warranty for future cable installs.
Self-Cleaning Optical Fiber Powers Supercontinuum Light Sources | Research & Technology | May 2022 | Photonics.com
Using two types of glass with different refractive indexes and that are stacked in a specific arrangement, researchers developed a multimode fiber with a parabolic refractive index that enabled transmission up to the mid-infrared and high nonlinearity. The spectrum of short pulses of light injected into the fiber massively broadened, to span from the visible to mid-infrared. The light beam remained smooth because of self-cleaning dynamics induced by the parabolic refractive index. Such a light source, with and ultrabroad spectrum, smooth beam, and high power, could be used in environmental sensing or high-resolution imaging for medical diagnostics.
