5G? IoT? Fiber Deep? 600G? We Are ready for networking at 2019!
For years we have all been talking about the emergence of 5G services, the Internet of Things (IoT) and the new high-capacity, low-latency network architectures that will be needed to support the resulting onslaught of bandwidth. Higher-speed data rates are critical to electronic evolution and revolution.
Here are some of my collection of newest trends and predictions for year 2018. have picked and mixed here quotations from many articles (linked to source) with some of my own additions to make this posting.
5G: The most newsworthy stories in wireless today are all about 5G. In 2019, we enter a cautious, early-adoption phase of this next generation of wireless technology. 2019 will be the year when we see the first commercial networks turning on and first handsets arriving in the market. Only a small number of users will get a first taste of 5G in specific geographic locations, using specific applications, none of which are ubiquitous or cost-optimized. For more details read my 5G trends for 2019 posting.
Deep fiber: Deep deployment of fiber optics into national network infrastructure might not be as glamorous as the eagerly anticipated launch of fifth-generation mobile networks (5G); however, it is just as important—maybe even more important. Wired broadband access supports as much as 90 percent of all internet traffic even though the majority of traffic ultimately terminates on a wireless device. Wireline and wireless networks are driving new architectures to support the move from 4G LTE to 5G infrastructure. In fact, 5G relies heavily on fiber infrastructure. Service providers in the access market are talking about the evolution of their plants to a Fiber Deep (FD) Architecture. FD architectures move the optical node (the optical-to-electrical conversion point) deeper into the network and closer to the subscriber. This means shorter copper, faster speed, more capacity and reduction in maintenance cost for both cable TV network and telephone line based access networks.
Ethernet: Faster Ethernet speeds are taken to use. These transitions are driven by the increasing global IP traffic. Hyper-scalers and service providers are moving from 100GbE to 400GbE Ethernet rates and beyond. In this speed development 56Gb/s And 112Gb/s SerDes Matter.
TSN: Time-Sensitive Networking (TSN) is a set of standards under development by the Time-Sensitive Networking task group of the IEEE 802.1 working group. TSN standards documents that are specified by IEEE 802.1 can be grouped into three basic key component categories that are time synchronization; scheduling and traffic shaping; selection of communication paths, path reservations and fault-tolerance. Industrial Ethernet networks embrace time-sensitive networking (TSN) technology to integrate operational technology (OT) and information technology (IT).
SDN: Software-defined networking (SDN) technology is an approach to cloud computing that facilitates network management and enables programmatically efficient network configuration in order to improve network performance and monitoring. SD-WAN applies similar technology to a wide area network (WAN). SD-WAN allows companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS.
IPv6: IPv4 and IPv6 are the two Protocols Run the Internet in 2019. The long-forecasted day the internet runs out of addresses has arrived and it marks a paradigm shift in the internet’s evolution. Though IPv6 has been available globally since 2012, it has seen a slow, if increasing, adoption rate. The migration to IPv6 is inevitable but will take time during that both systems are in use. In many networks a notable amount of traffic is already IPv6.
New Internet protocols: Internet security gets a boost with TLS 1.3. Also HTTP is in process of switching to a protocol layered on top of UDP. Today’s HTTP (versions 1.0, 1.1, and 2) are all layered on top of TCP (Transmission Control Protocol) that is not very optimal in today’s applications as SSL over TCP requires subsequent round trips to establish the encrypted connection.
IoT: The IoT world is here, and the level and rate of convergence is increasing in volume and velocity. We will see the evolution of converged networks for IoT applications in mind. Network convergence (version 2.0) is here with changes and improvements made since the first converged network (Convergence 1.0). TIA TR-42 (Telecommunications Cabling Systems ANSI/TIA-568 family), BICSI (TDMM and others) and proprietary or third documents must adapt and adjust.
PoE: The IEEE 802.3bt standard, approved by the IEEE Standards Association Board on September 27, 2018, included some significant enhancements especially for LED lighting systems. This specification allows for up to 90W of delivered power for cable lengths of up to 100m through the use of all four pairs of wires.
Trade wars: It seem that there is a high tech “trade war” between USA and China. It affects specifically networking business. Big Chinese manufacturers Huawei and ZTE are have received sanctions and their products are not wanted by many countries citing their business practices and potential security nightmares. For example Japan to halt buying Huawei, ZTE equipment and Huawei has been under fire in UK, just to mention examples. It seems that the business that is lost by Huawei and ZTE could benefit Ericsson and Nokia in the 5G base station markets for short term.
Security: The internet is going to hell and its creators want your help fixing it. All agree on one thing however: Right now there is a serious battle for heart and minds, the future of the internet and global society itself. There seems to be need for a conference to address the fact that people increasingly see tech as a threat and no longer as a pure force for good. Government set to revise internal rules on procurement to protect national cybersecurity. Your DNS might be broken, and you don’t even know it. Some DNS old hacks gets thrown out of use by February 1st, 2019.
WiFi: WiFi technology gets new marketing naming. The numerical sequence includes: Wi-Fi 6 to identify devices that support 802.11ax technology, Wi-Fi 5 to identify devices that support 802.11ac technology, Wi-Fi 4 to identify devices that support 802.11n technology.
Faster mobile: Mobile networks are getting faster in many countries. Mobile networks are killing Wi-Fi for speed around the world. Average data speeds on mobile networks now outpace customer’s Wi-Fi connection, on average, in 33 countries. That’s the The State of Wifi vs Mobile Network Experience as 5G Arrives.
Energy efficiency: We need to develop more energy efficient networking technologies. Today, information and communication technologies globally consume 8% of electricity and doubles every year.

Extreme Bets On Cloud to Unseat Cisco, Aruba
https://www.sdxcentral.com/articles/news/extreme-bets-on-cloud-to-unseat-cisco-aruba/2020/11/
With yet another strong quarter of sequential growth under its belt, Extreme Networks has its sights set on unseating rivals Cisco and Aruba in the wireless and LAN switching market.
Extreme Networks CEO Ed Meyercord told SDxCentral that the company’s strategy is simple: provide customers an “effortless experience.”
“That’s where our message is resonating,” he said. “We’re winning business frankly because of the ease of deployment and ease of deploying the cloud.”
At the heart of this strategy is ExtremeCloud IQ, the company’s unified cloud management console, which it acquired from Aerohive in 2019. In a bid to simplify hardware and software licensing, the company has adopted a tiered model. Basic deployment and management capabilities are available as part of Extreme’s freemium Connect tier, while more advanced functionality can be unlocked with the company’s Pilot tier.

SpaceX snags $885M from FCC to serve rural areas with Starlink
https://techcrunch.com/2020/12/07/spacex-snags-885m-from-fcc-to-serve-rural-areas-with-starlink/?tpcc=ECFB2020
The FCC has just published the results of its Rural Digital Opportunity Fund Phase I auction, which sounds rather stiff but involves distributing billions to broadband providers that bring solid internet connections to under-served rural areas “on the wrong side of the digital divide.” Included is $885 million earmarked for SpaceX, whose Starlink satellite service could be a game-changer for places where laying fiber isn’t an option.
Only three other companies garnered more funds: Charter with $1.22 billion; Minnesota and Iowa provider LTD Broadband with $1.32 billion; and utility collective Rural Electric Cooperate Consortium, with $1.1 billion.

What’s better for transmitting signals than the glass in standard optical fibers? New hollow-core fibers show the answer is nothing.
New Hollow-core Optical Fiber Is Clearer Than Glass
https://spectrum.ieee.org/user/login?redirectUrl=https://spectrum.ieee.org/tech-talk/semiconductors/optoelectronics/new-hollow-core-optical-fiber-is-clearer-than-glass
Conventional fiber optics guide light through solid glass cores that are extremely transparent. The clearest fibers have loss as low as 0.142 decibel per kilometer. Which means that more than one percent of input light remains after a hundred kilometers. Yet solid glass fibers cannot carry very high powers, particularly in short pulses, limiting their use for applications including delivering intense light for laser machining.
Now a team at the University of Southampton’s Optoelectronics Research Center has made hollow-core fibers that are clearer than solid-core fibers at some important wavelengths.
the air-filled microstructures in the fiber were very complex, while these “photonic bandgap” fibers enabled transmission of too limited a range of wavelengths to be practical.
In recent years, Francesco Poletti at Southampton has pioneered a new range of experimental fibers that depart from Russell’s basic idea by limiting the microstructure only to the hollow core of the fiber.
“Lumenisity Ltd., a startup from our group, has already installed [fibers with the new design] in optical cables running live traffic,” Poletti said in an email. Light travels 50% faster in air than in glass, so the initial market for hollow-core fibers is short data links requiring extreme speed. He cites financial transfers, 5G and links inside and between data centers. It’s a potential boon for high-frequency security traders. However, it has yet to match the transmission of solid-core fibers in the telecommunications band at 1550.
Now Poletti’s group has developed new hollow-core fibers that match or even beat the transparency of solid-core fibers in key wavelengths outside the telecommunications band, where glass is most transparent. They tailored fibers for 660 and 850 nm photons (these bands in the red and near infrared are widely used in biology and quantum networks) as well as for 1064 nm (another near infrared band that’s popular for industrial laser machining).
A handful of vendors already sell older types of hollow-core fibers to deliver ultrashort laser pulses that deliver a rapid series of pulses to cut glass for smartphones. “There is no alternative to hollow-core fibers because solid-core fibers cannot compete,” Poletti says. The intense light pulses have to be kept out of the glass to avoid damaging it.
So far, glass cutting is a small share of the overall market. But he says his group’s new hollow-core fibers can transport “kilowatt scale continuous powers in a fundamental mode over tens or hundreds of meters, and could soon challenge solid-core delivery fibers in the much bigger market of [industrial machining with] high average power lasers.” Analysts put sales well into the billions.
The new hollow-core fibers also have other advantages besides damage resistance and faster light speed. Keeping light out of the glass avoids nonlinear effects that can distort signals and can improve quality of the transmitted laser beam.
Fundamental limits of the new fibers are unknown. Light scattering dominates the loss of solid-core fibers at wavelengths shorter than the telecommunications band. “Up to a few months ago, we thought that scattering of light at the air-glass interfaces [in hollow-core fibers] would eventually dominate loss at those shorter wavelengths,” Poletti says. But the loss keeps dropping as they improve fiber fabrication, and he now speculates that in a few years the new hollow fibers might be ten times clearer in that band than the fundamental limit solid-core fibers.

Scientists Create Underwater Internet
First there was Hi-Fi, then Wi-Fi. Get ready for Aqua-Fi.
https://www.sportdiver.com/scientists-create-underwater-internet?utm_campaign=ww-en-gene-pros-social_media-blog_posts&utm_source=facebook.com&utm_medium=post-link&utm_content=aquafi&social_post_id=sf241167944&spredfast-trk-id=sf241167944
Checking your notifications on a dive or live-streaming from the reef may not be such a far-off reality thanks to an underwater internet dubbed “Aqua-Fi.”
Developed by researchers at the King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, Aqua-Fi uses a combination of lasers and existing computing technology to connect devices to the internet more than 30 feet underwater.
With the new technology, researchers were able to place a brief Skype call from a waterproof smartphone, using a standard Wi-Fi signal to connect to an underwater modem.
The modem is a Raspberry Pi computer, which is about the size of a credit card. It converts a wireless signal to an optical laser signal, which then is beamed to a receiver attached to a surface buoy. This creates a bi-directional wireless connection.
In order for Aqua-Fi to keep a constant connection, the lasers have to stay aligned with the buoys and have power banks to store their energy. Because of strong waves and currents, lasers can easily be knocked off their alignment. The team is currently looking into options to make the signal more reliable
Because Aqua-Fi is Wi-Fi based, it can also transfer GPS coordinates of underwater devices, Shihada says.

IN 2021, WE NEED TO FIX AMERICA’S INTERNET
We pay twice as much as Europe for high speeds, assuming we can even get them
https://www.theverge.com/22177154/us-internet-speed-maps-competition-availability-fcc
AT&T wants to sell me 1,000Mbps fiber-optic internet, and I’m beyond ready to pay for it. In fact, I’ve already signed the contract at least nine times now.
But like tens of millions of my fellow citizens across the United States, I don’t actually have the ability to switch. Across the country, the FCC and internet service providers are pretending there’s competition in an unimaginable number of places where it doesn’t actually exist. It’s a nationwide problem
Today, I pay $100 a month for Comcast internet, and the cable company’s speeds leave something to be desired. My wife, a video producer, can’t reliably upload her company’s videos to its FTP servers. The family videos we shoot on our smartphones take hours to appear in Google Photos, and there’s no point in me even trying to stream games to YouTube or Twitch. While my download speed is decent at 200Mbps, the uploads are absolutely atrocious at just 5Mbps up
AT&T seems like the obvious answer. The company’s fiber network offers 1,000Mbps downloads and 1,000Mbps uploads for $70 a month, no data cap whatsoever. Competition is good, eh? The only problem is that AT&T doesn’t actually serve my address… even though it continues to insist it does. The company’s field technicians have visited my home easily a dozen times now, but their conclusion is always the same: AT&T buried its fiber in the wrong place.

St. Helena’s New Undersea Cable Will Deliver 18 Gbps Per Person
https://spectrum.ieee.org/telecom/internet/st-helenas-new-undersea-cable-will-deliver-18-gbps-per-person
Since 1989, the island of St. Helena in the South Atlantic has relied on a single 7.6-meter satellite dish to connect the island’s residents to the rest of the world. While the download and upload speeds have increased over the years, the roughly 4,500 Saints, as the island’s residents call themselves, still share a measly 40-megabit-per-second downlink and a 14.4-Mbps uplink to stay connected.
But come April, they’ll be getting quite an upgrade: An undersea cable with a maximum capacity of 80 terabits per second will make landfall on the island.

Lumenisity unveils hollow-core fiber-optic cable for 10 Gbit DWDM transmission over 10 km links
The deployable fiber-optic cable contains hollow-core fiber based on nested antiresonant nodeless fiber (NANF) technology.

Fiber-optic cabling maker Lumenisity Limited (Romsey, UK) has unveiled a new hollow-core fiber cable, called CoreSmart, for dense wavelength-division multplexing (DWDM) operation over links in excess of 10 km.
In hollow-core fibers, light propagates in an air-containing core formed by microscopic capillaries. They have a big advantage over conventional solid glass fibers: data travels 50% faster in hollow-core fiber, as the light propagates in air. Propagation in air offers the potential for higher data capacity and extended reach due to the 1000X reduction in power-induced nonlinear optical effects that occur in glass. A key challenge has been both the design and manufacturing processes — in particular, making the fibers

If the company can pull it off, Starlink would be faster than many ground-based gigabit broadband networks.
SpaceX is aiming to one day deliver 10Gbps internet speeds over its satellite internet system, Starlink—a ten-fold increase over the company’s previous 1Gbps goal.
Last week, SpaceX gave an update to the FCC on the current status of Starlink, which is already supplying broadband to residents in rural areas in the US, Canada, and the UK. The company’s presentation points out the system can currently deliver 100Mbps download speeds to users. But the long-term goal is to upgrade speeds to 10Gbps.
If the company can pull it off, Starlink would be faster than many ground-based gigabit broadband networks, and thus create some serious competition in the ISP market.

Nokia ja Elisa kertoivat eilen onnistuneesta testistä, jossa joitakin Elisan runkoverkon reitittimiä päivitettiin tukemaan peräti terabitin datanopeutta. Tämä onnistui päivittämällä Nokian 7950 XRS -reitittimen linjakortit ja ohjelmistot.
Terabitti sekunnissa on iso hyppäys eteenpäin runkoverkkojen nopeuksissa. Valtaosa verkoista on tällä hetkellä liitäntänopeuksiltaan 100G-tasoa tai sitä hitaampaa. Elisan teknologiajohtaja Kalle Lehtisen mukaan testi osoitti, että operaattorilla on Nokian ansiosta kyky hypätä verkoissaan 1T-luokkaan.
Tarve jatkuvasti nopeammille yhteyksille on jatkuva. Kovin nopeasti Elisa ei verkkoaan ole T1-luokkaan siirtämässä. – Laajentamista tehdään vielä myös aktiivisesti 100- ja 400G-liityntäyhteyksillä ja arvioimme suurempien, kuten 1T linjanopeuksien käytön laajentamista, hän tarkensi.

Seeing the Light: Lasers for Data Storage, Space Comms
https://www.eetimes.com/seeing-the-light-lasers-for-data-storage-space-comms/
Laser technology is emerging for both a high-capacity data storage technique as well as a deep-space communications link.
A startup is developing a space-based framework for boosting data storage using laser technology. Separately, NASA is planning to launch an optical communications relay that would demonstrate the ability to transmit and received far greater data volumes than conventional RF links.
In the case of storage, data in motion, especially the variety cast as “big,” is generally to be avoided since movement leads to latency which slows data access.
What if the transport mechanism for data movement was light? That’s the value proposition of a New York startup developing a space-based data storage framework. LyteLoop, which this week announced a $40 million funding round, proposes to use ultra-high bandwidth lasers to store up to exabytes of data via what it describes as an “endless loop between satellites.”
Along with scaling advantages, the light-based approach that puts data in a “constant state of perpetual motion” is promoted as more secure while consuming less power than traditional data center servers.

Reporters like me called him and wrote articles, talk of his plight went viral on the Internet, his ad made an appearance on Stephen Colbert’s Late Show, TV networks interviewed him for nightly news broadcasts, and AT&T executives sprang into action to minimize the public-relations damage.
Now, barely a week later, Epstein’s home in North Hollywood, California, has AT&T fiber service with unlimited data and advertised speeds of 300Mbps in both directions. In a speed test yesterday, download speeds were 363Mbps and upload speeds were 376Mbps. It’s a gigantic upgrade over the “up to” 3Mbps DSL he and his wife, Anne, struggled with before.
Normally, complaints about AT&T DSL don’t lead to fiber-to-the-home upgrades the next week, as AT&T has essentially abandoned the old phone network in large parts of the country where AT&T has not deemed it profitable enough to install state-of-the-art technology. But it appears we have discovered what it takes to kick AT&T into its fastest fiber-installation mode, and the answer is a quarter-page Wall Street Journal print ad.

Cable and connectivity are the necessary, basic building blocks and foundation for transmitting and receiving all communications. Cable connects everyone to everything through the wired and wireless network infrastructure—from healthcare and educational institutions to conferencing, entertainment and social media. The 2020 pandemic taught us, or reinforced for us, that the internet is a required utility and priority number one for dependable communications. Every bit of data that is stored in the cloud—i.e. in a data center—cannot be secure or functional without a robust cabling system.
If the internet is the common bond that keeps everyone and everything connected, then the cable is the glue. Moving forward into the next generation of the Internet of Things (IoT), artificial intelligence (AI), 5G and smart cities/building applications, reliable data transmission in real time becomes critical to how modern society functions. This data transmission, which was once simply a means of communication, is evolving into a core necessity, relying solely on the infrastructure and the sum of its parts.
The evolution and growth of applications and new technologies are driving the need for high-performance and high-value cable, a crucial infrastructure necessity that is often overlooked or thought of as a commodity. Today’s critical applications require 100% reliability and ever-higher data transmission rates over this new cable, now with the added duty of supporting Power over Ethernet
