December 17, 2020 — Networks of the future need to be scalable to keep up with burgeoning bandwidth demands, according to Greg Luhman, business development manager at ADTRAN.

“There has been a 56 percent increase in upstream usage, largely due to video conferencing,” said Luhman, during an event entitled the “End-to-End Gigabit Experience,” which aired Monday as part of Fiber Connect 2020. “We must start considering upstream demands in the home when building networks, as remote work and learning are part of a new normal.”

“We’re starting to see bandwidth usage numbers creep up,” said Luhman. “The average network is using the 2.5 Gigabit downstream and 1.25 Gigabit upstream capacity available in gigabit passive optical networks,” he said, adding “over the next few years, we expect to see constraints in GPON networks.”

To keep up with growing bandwidth demands, Luhman recommended internet service providers consider making a switch in the kind of passive optical fiber network technology they utilize. Luhman detailed that XGS-PON, a PON-based, fiber access technology, which can deliver upstream and downstream symmetrical speeds of up to 10 Gigabits per second, is steadily becoming the new industry standard.

“Many internet service providers are switching to XGS-PON to prepare for bandwidth demands of the future,” said Luhman. Providers are aiming to take advantage of the additional bandwidth and capacity offered, to deliver increased overhead to networks for customers, who are beginning to expect gigabit speeds.

XGS-PON further has many additional applications, such as the capability to mix businesses and residential services on the same network, making it a more future-proof option.

Unlike NG-PON, a previous generation of fiber network technology which held great capabilities but cost unreasonable prices, the industry has been able to optimize the cost of XGS-PON, according to Luhman.

Luhman also noted that transitioning GPON to XGS-PON in networks is relatively simple, as the two technologies can coexist. Network engineers must merely install a coexistence module and start to overlay XGS-PON overtop GPON. “The coexistence module brings all wavelengths together on the same fiber,” said Luhman, adding that “this is a good model for a brownfield situation, where you may have a handful of customers who want to move to a faster, alternative network.”

Tony Thakur: Bandwidth Consumption, 5G and Rural Coverage Will Drive Fiber in 2022

In the coming year, fiber-optic infrastructure will needed to manage and offer increases in bandwidth capacity.

All indications show that we will continue to consume more and more bandwidth in support of our connected online lifestyles.

Without a doubt, the recent move to the hybrid work/learning model and the need to be constantly connected has increased internet usage. And, as video streaming, e-gaming and video conferencing grow in popularity, the drive for more bandwidth will rise.

To deliver much-needed high speed internet service to support these applications, more Fiber will be required to homes and businesses. Fiber infrastructure is capable of delivering huge bandwidth amounts at needed speeds and will be deployed throughout long haul, metro and last mile networks.

Here’s a look at what’s important to telecom networks, some of the drivers behind the rising trend to fiber, and why fiber is here to stay.

What is behind the rising trend to fiber?

There are several drivers, including:

Bandwidth-consuming applications. When multiple devices are running multiple applications simultaneously, bandwidth is quickly used up and buffering and lag can occur. Thus, networks will need to add more and more bandwidth. The FCC Household Broadband Guide cites rough guidelines for broadband speeds needed for various activities.  We can expect to see increases of speed from gigabit to terabit in the future.

5G deployments. This is another area where there is significant growth. Ultra-fast networks like 5G will require large bandwidth connectivity from the towers to the Switching Center. Fiber has become the standard for backhaul networks. We will continue to see more fiber deployed as 5G grows.

Rural coverage.  Fiber has been widely deployed in the metro areas and for long haul networks. The Infrastructure Investment and Jobs Act signed into law November  15, 2021 includes $65 billion in funding for broadband deployment to improve internet services for rural areas, low-income families and tribal communities. With more focus on providing high speed internet, there will be more and more fiber deployments in the access or last mile across the country. This trend is likely to continue over the next three to five years, especially in the rural areas where access to the internet is limited to dated technologies and delivery methods. We will see more and more fiber to the home deployments as well.

Fiber technologies to be aware of

Here are some fiber technologies that not only facilitate the additional bandwidth, they simplify processes, enable automation and provide new capabilities:

GPON or Gigabit Ethernet passive optical network uses a single fiber with a point-to-multipoint architecture for the last mile to deliver higher speeds to homes and businesses. GPON was introduced several years ago, with downstream capacity of 2.5 G and upstream of 1.2 G. The newer version, XGS PON, provides additional capability with 10 G symmetrical speeds. Most deployments going forward will employ XGS PON to enable higher bandwidth and speeds.

SD-WAN or software-defined wide-area network technology has been widely adopted in the telecom industry today. Customers can obtain the security, improved performance and diversity from their premise to the cloud and other locations, leveraging multiple circuits. That connectivity can be internet, Ethernet or wireless. The technology also includes orchestration capability that simplifies the operational process. This will continue to be adapted as the workforce shifts to Hybrid remote work environments with more apps and data in the cloud.

SDN or software-defined networking is another technology used for cloud connectivity and other Ethernet-based services.  The network is connected to data centers and cloud providers to enable “on-line” type services. For example, the SDN network allows for demand-type services. Bandwidth can increase or decrease in minutes via a portal and customers pay for what they use versus the traditional monthly recurring circuit cost model.

Growing cloud connectivity

More and more organizations continue moving to and using cloud connectivity to access their applications and data that reside in cloud platforms such as Amazon Web Services (AWS), Microsoft Azure, Google, Oracle, IBM, SAP, Nutanix, Salesforce, Alibaba and others. Improved performance, faster access, and more flexibility to access tools and data are merely a few of the benefits.

While some rely on the internet to reach the cloud, there are drawbacks such as latency, limited bandwidth and less than top-level security. A direct connection to cloud platforms via fiber is more secure, faster and more reliable, thus improving performance for applications and workloads.

The private cloud or data center requires significant investment to build and operate. A cloud connect via fiber enables easy access to applications anywhere in the cloud, from any location. Data can be stored at multiple locations around the world, providing better flexibility.

Staying power

Technology trends come and go. Remember when people relied on dial-up internet access and carried flip phones, Blackberries or pagers? Yet we sometimes overlook the complexity that goes into deploying new technologies. It is not only about the cool technologies themselves, but so much more. Innovation depends upon talented people who can implement services such as cloud.  Truly, it is the people that make the difference in how we successfully adapt to new technologies.

UTOPIA Fiber Pushes into Southern Utah

The expansion will bring fiber-to-the-home to residents of two additional Utahn cities.

Roger Timmerman, executive director of UTOPIA Fiber

WASHINGTON, January 6, 2022 – Community-owned fiber optic network UTOPIA Fiber announced in a press release Wednesday that it will implement fiber-to-the-home service in the Utah cities of Cedar Hills and Santa Clara.

The expansion into Washington County’s Santa Clara marks UTOPIA Fiber’s first expansion into southern Utah.

“We’re really excited to continue our momentum in Utah County and to venture into southern Utah where Santa Clara will become the first all-fiber city in Washington County,” said Roger Timmerman, executive director of UTOPIA Fiber.

This move marks UTOPIA’s 18th and 19th city expansions and comes with a $12 million price tag. Just last month, UTOPIA completed its network in Payson City, Utah. The telecom provides business services in 50 cities.

In all its serviced cities, UTOPIA offers residential speeds of up to 10 Gigabits per second and business speeds of up to 100 Gigabits per second – both the fastest respective speeds offered in the U.S. In total, the network provides fiber availability to more than 130,000 businesses and residences across its 50 serviced communities.

In its press release, UTOPIA promoted its expansion by citing research showing that residential and commercial property values increase when they are served by a fiber network. It added that its open access model, which allows infrastructure sharing with other providers, “protects a net-neutral internet without throttling, paid prioritization, or other provider interference.”

UTOPIA Fiber is a Broadband Breakfast Sponsor.

WASHINGTON, December 16, 2021 – Though open access projects are finding success in some parts of the country, some experts remain unconvinced that the model will prove viable for most communities.

During the Broadband Breakfast Live Online event on Wednesday, UTOPIA Fiber Executive Director and CEO Roger Timmerman and Jim Baller, partner at law firm Keller and Heckman LLP partner, debated the merits of the model that allows service providers to use the same infrastructure.

Timmerman, whose UTOPIA Fiber operates an open access model in Utah and southern Idaho, said his company has seen success with open access fiber infrastructure being a sustainable and scalable model to meet whatever demands future technology may place on consumers and businesses.

Sixteen internet service providers use infrastructure built and leased by UTOPIA, a sponsor of Broadband Breakfast, to offer residential areas up to 10 Gigabits per second symmetrical speeds.

But Baller said he is concerned that shared infrastructure will just force providers to engage in a price war that will lead to a race to the bottom. He painted a picture of an open access model whereby wholesalers who lease their infrastructure to internet service providers find themselves in a kind of purgatory where no one is making any money – the wholesaler is unable to compel ISPs to raise their prices, and the ISPs feel they can only compete by undercutting their competition. He described the situation as “open access run amok.

“I would love to see open access work, I just urge caution, because you need to do hard analysis in a particular market,” said Baller. “Open access may not be something that is possible up front, but it can be over time.

“You have to look at the numbers very carefully and assess what the circumstances are and make your decision based on what is in front of you,” he said. “There is no one size shoe that fits all in these circumstances.”

In response to the criticism that open access will drive prices into the ground, Timmerman said that the largest provider in UTOPIA’s network is also the most expensive. “It has not been a race to the bottom, it has actually been the opposite,” he said.

Timmerman added successful providers are ones “that can differentiate themselves on quality, reputation, consumer privacy,” and added that the nature of the model allows them to do so at a low barrier to entry.

Timmerman described how UTOPIA has been able to “raise the bar” on their standards for accepting ISPs to partner with, and how they have had to “beat [companies] off with a stick,” due to increased interest in working with UTOPIA.

“We want well established, successful companies because we have a lot on the hook – I cannot afford to put [these] assets at risk with some fly-by-night company. We work hand in hand with providers on quality and reputation to make sure that we both win and make sure that cities and participants win.”

For his part, Timmerman conceded that there is no “one size fits all model,” but argued that most communities’ needs can be satisfied through the framework of an open access build.

“We have had a lot of conversations with communities; what [communities] have to bring to the table and what their needs are, and how we might fill all those roles and deliver a successful system.

“The more a city wants and dictates into a project, the more skin in the game they may need to have,” Timmerman added.
