Networks running on fiber optics are generally state-of-the-art, but even advanced networks can be improved. That means faster speeds and more traffic density. Fortunately, lots of older fiber is capable of upgrading to faster networks including WDM, but it may need testing to ensure it will work, especially if the links are over 20 km and upgrades are to 10 gigabits (Gb) and above.
Wavelength Division Multiplexing (WDM) 101| WDM Technology in Optical Fiber Communication
Wavelength division multiplexing (WDM) carries great potential to help network operators stay ahead of growing demands for bandwidth. As we continue to split the light into more and more wavelengths, the potential capacity of just a single fiber strand grows dramatically.
Fastest-Ever Internet Speed Could Download Whole Netflix in Seconds
The researchers from University College London achieved the new world record for the fastest internet of 178 terabits a second, which is five times faster than the previous world record held by a team in Japan and close to the theoretical limitations of the data transmission set out by American mathematician Claude Shannon in 1949. This means if that data connection were wired to your home broadband, it would allow you to download 22million HD photos in under a second, and download more than 220 4K-quality movies in a second.
Webinar: Cabling Standards Update
With many North American cabling projects specified to comply with TIA standards, these documents are among the most relevant to all parties involved in cabling-system design, installation, certification or management. This webinar will provide an update on both new and existing standards that are relevant to ICT professionals. Attendees will learn how to identify and understand the elements of a cabling standard that matter most to cabling design, installation & maintenance professionals; standard specifications related to high-density optical fiber cable; and the latest developments in copper cabling standards including single-pair cabling, PoE and cabling for WiFi support.
Furukawa first with high-density fiber optic cable into 1.25 inch conduit
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.
Usher in an era of light for campus networks by choosing fiber optics over copper
Traditional networks may seem adequate, but the exponential growth of data transfer is putting traditional campus networks to the test. In short, copper wiring limits speed and distance – and both are critical for an effective campus network. Copper only offers transmission speeds up to 1Gbps and reach of 100 meters; it will suffer signal losses and tremendous data slowdowns if they go beyond. Additional investment such as signal boosters or recabling are needed to maintain network performance if the site is particularly large.
Company opens fiber-optics factory in Aurora
Capitalizing on growth in 5G technology and with support from state and local officials, a startup company called viaPhoton has opened a fiber-optics factory in Aurora, where it is hiring 30 people and hopes to add another 200 employees in three to five years.
CEO Baber Abbas said the company will supply data centers and mobile communications companies throughout the Midwest. Its presence here will help Illinois expand access to 5G services statewide.
Black Swans and Fiber Networks
A black swan event is defined as “an unpredictable event that is beyond what is normally expected of a situation and has potentially severe consequences.” The phrase originated because people assumed that black swans didn’t exist because nobody had recorded seeing one – until finally someone did. It turned out black swans existed but were extremely rare, and it was hard to predict when or where someone would encounter one. The COVID-19 pandemic in some ways has been a black swan event, and the communications sector has been no exception. One impact on our sector is that data traffic has shot up at an unprecedented rate, a result of schools closing and orders to shelter in place and work from home. This experience is one example of a fundamental truth of network design: patterns of demand in data traffic are hard to predict (other than that they will grow rapidly on average). The solution is to focus on building physical access networks that have the capacity to respond to changing demands, and the accessibility to make use of that capacity where and when it is needed.
Webinar: Fiber Deep Networks for Today’s Enterprise: Part 1
How can you deliver a reliable 4th Utility connected experience so you can face the demands of a modern network? In this webinar, Corning discusses how optical network solutions provide a future-ready platform that can help support in-building applications like Wi-Fi, cellular, cameras, A/V, lighting and more. We will also walk through an Intelligent Building case study that used remote powering, software defined networking, cellular and optical network solutions to provide an easy to manage, scalable, and cost-effective common infrastructure that saved more than 25% over traditional copper networks.
DWDM is an optical multiplex technique. It combines multiple discrete transport channels of different wavelengths and transmit them on a single optic fiber. For example, if we multiplex 32 signals of STM-1 level, then optic fiber capacity will be increased from 2.5Gbps to 80 Gbps.This DWDM tutorial covers basics including DWDM transmitters and receivers and describes optical fiber basics, optical amplifier and other system components.
