- 5. Impact of 5G on a fiber network *By 2021, the world will have 27.1 billion networked devices, up 58.47 percent from 17.1 billion in 2016. Forty-three percent of these devices will be mobile-connected, and they will consume far more data; a smartphone in 2021 will consume an average of 14.9 GB of data monthly, four times the 2016 level. Small cells provide a preview of what 5G networks will look like. 5G is expected to use much higher frequencies, known as millimeter wave, because these frequencies have the inherent ability to carry much larger amounts of data. But achieving these higher data rates is only possible at a range of one-tenth to one-fifteenth the distance covered by 4G LTE. * http://www cisco com/c/dam/m/en_us/solutions/service-provider/vni-forecast-highlights/pdf/Global_Device Growth Traffic Profiles.pdf

A tower like this, served by fiber, can potentially serve 10 square miles. The white square shows one square mile. This sketch showing one square mile, provides one estimate of how many 5G cells would be needed: 60 each covering a 750 ft. diameter area. These small cells could require up to eight miles of fiber each. **Source Fiber Broadband Association December 2017 whitepaper – The road to 5G is paved with fiber**

- 8. Why fiber? • Single-mode fiber has been the predominant type of fiber deployed in FTTH networks. • Optical fiber was commercially introduced in the early to mid 1980s, and the basic design and construction has stayed the same. • Fiber cables deployed in most networks during the 1980s are still commonly used today. • Fiber technologies have significantly improved since the 1980’s making fiber much more cost effective and easier to install today.

The ideal network design Wireless and FTTH networks converged together • Would “future proof” the network for increasing bandwidth demands • Offers true 1 Gig service to customer premises • Consumers would have the ability to move seamlessly between the mobile and FTTH network The integrated network will address two factors that will always exist • Consumers will continue to demand higher bandwidth speeds • Consumers want the ability to be mobile

Rather than splicing in each NAP, pre-connectorized MPO cables are deployed to connect each YourX terminal. On the drop side, deploy reels with 900um fiber plug into the terminal on one end and terminate at the TAP demarc point on the other end. Deploy reel with 900um fiber– Pre-terminated on both ends Distribution Cabinet Drop Terminals Test Access Point Houses deploy reels Connectorized MPO cables

- Intro - Hello my name is Brian Schrand and I’m the director of application engineering at Clearfield. Topic - FTTH: Even More Relevant with the Advent of 5G
- First let’s talk about how we got to this point. As you can see from this side each year the importance of high speed internet is moving to the top of the must haves list. Why? I think if we look at the demographic of people who are renting? The average age of an American today is 38 years old. The 20 and 30 sums are making up the bulk of renters. They’ve grown up with high speed internet and are accustom to having it.
- Technology timeline So how much bandwidth is enough? I remember the old industry adage that said, “What are they going to do with all that bandwidth?” Nobody really aske’s that question any more. Give consumers higher speed services there will always be a developments made for them to consume it. Bandwidth consumption is increasing exponentially year after year. Study by Cisco in 2015 discovered that by 2019 80% of internet traffic will be mostly consumer video. Half the planet - 3.9 billion people will have access to the internet by 2019 but the number of devices able to access the web will be three times as high as the population or 12 billion. A recent study done by Parks Associates found that U.S. broadband households have more than seven video devices, including TVs, computers, tablets and smartphones. As speeds increase - need to drive fiber closer to the edge of the network. All the written words in the world add up to 4 Exabyte's of information. The Internet has transmitted 16 Exabyte's of information in the past four years. How long will it be until 1 gig to a home isn’t sufficient enough? Whatever the future brings the need to drive fiber deep into the network will be a reality.
- What type of network should you build to deliver high speed internet? Across the globe the amount of mobile devices accessing the web continue to increase. Today the number is roughly 90%. This statistic would suggest that wireless is obviously the answer. Not necessarily – a fiber rich network will be needed to backhaul all this information. If you’re building a dense fiber network for wireless backhaul why not pay today’s labor rate and plan for FTTH?
- Impact of 5G on a fiber network Keep stating that a fiber rich network will be needed for a 5G network. Let’s take a look at how 5G really impacts the network? Another survey done by Cisco states – In 2016 there were 17.1 billion networked devices in the world. By 2021 there will be an estimated 27.1 billion. This is a 58.47% increase 43% of the 27.1 billion devices will be wireless They will consume far more data – Smartphone in 2021 will consume an average of 14.9 GB of data monthly, four times the 2016 level. Just like the current 4G the antennas 5G will also need to be fiber fed. The difference is that 5G’s coverage is 1/10th the area of 4G. This is because 5G utilizes higher frequencies. The average distance that’s being reported to deliver 1 gig is a average of 750 feet.
- Wireless network comparisons How are 4G and 5G different? This slide shows the coverage comparisons of 4G to 5G 4G – one fiber fed tower can potentially feed 10 sq. miles. 5G – 60 small cell sites per sq. mile with an avg. of 8 miles of fiber backhauling info for each. Total fiber needed per sq. mile = 480 miles.
- 5G small cell site comparison Smaller 5g antennas will be needed to cover gaps in the 5G network. At some point fiber will be needed at each building to feed the 5G antennas contained within the building. Info from AT&T antenna solutions group.
- Why fiber? As network speeds continue to grow fiber is the best option for future proofing a network. Unlike wireless technologies, single mode fiber has stayed consistent since its development. Wireless upgrades are expensive capital investments. Install fiber onetime – only challenge is to make sure the fiber count is large enough. Fiber is future proof. We don’t really know its capacity. A research group in 2014 at the technical university of Denmark developed a way to transmit 43 terabits a second on a single fiber with one transmitter.
- This slide is from ISE November 2017 publication. It shows that without more fiber, carriers will be unable to support the projected fourfold increase in mobile data traffic between 2016 and 2021. A Deloitte Consulting LLP analysis estimates that the US requires between $130 and $150 billion over the next 5-7 years to adequately support broadband competition.
- FTTH Network Diagram Typical FTTH network diagram. As the network gets closer to the customer it becomes more expensive to build. The drop to the home and the home installation is the most expensive piece.
- Fixed Wireless Diagram Fixed wireless design has eliminated the most expensive piece of the network. Wireless equipment to be deployed closer to the customer with fiber feeding each small cell. It would make sense to plan/provision the network for taking fiber all the way to the home at some point in the future.
- The ideal network design The ideal network design would be to incorporate wireless and FTTH. This design will give deliver the bandwidth that customers are demanding now, as well as those in the future, and meet their mobility requirements. Seamless network without any holes.
- Blended Network Diagram Blended network - makes the most sense. However, it can be an economical challenge. Key to building a blended network is flexibility. One product solution that can deliver whatever is required. Plug-n-play functionality
- Dissecting the cost of a FTTH network Typical FTTH network deployment – lots of splicing in multiple locations. Not much flexibility for adding network elements in the future. Adding more connections to the network is costly and take time.
- Modular Technology / Plug-N-Play YourX platform – flexibility of modular network. Provision as much or as little plug-n-play functionality as you like. Can easily add new network elements quickly.
- Modular Technology / Plug-n-play for wireless (**last two slides**) MPO Cassettes that plug into the network easily
