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.
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.
