Key Points

  • The optical lab’s capabilities range from innovation to prototyping and testing.
  • Operators can use the lab to explore the benefits of 10G PON, 25G PON and 50G PON.
  • It also offers them a space to learn how to integrate PON technologies into their networks.

Optical communication — transmitting light waves through fiber optic cables — continues to be the foundation for providing high-speed broadband services to consumers. Whether the network solution is 100 percent fiber to the home or fiber is just an overwhelming majority, you’ll find fiber optics at the root of the solution. To acknowledge the foundational prominence of fiber optics in our industry, CableLabs is expanding the capabilities of our Optical Center of Excellence (OCE) to include state-of-the-art passive optical networking (PON) equipment.

Alongside the hustle and bustle in the cable industry to deploy DOCSIS® 4.0 technology, another 10G solution quietly plods along with pinpoint precision: fiber to the premises (FTTP). In FTTP, the premises can represent a home, business, campus, multiple-dwelling unit, etc.

The advancements of coherent passive optical networks (CPON) will lead to a robust and noticeable boost to the customer experience in businesses and the home. The benefits include providing faster downloads, less buffering and increased capacity for many consumer devices using applications simultaneously. Since Passive Optical Network (PON) technology was first deployed in fiber-to-the-home (FTTH) networks over 30 years ago, it has evolved from 622 Mbps to the 10 Gbps capacity being deployed by network operators today. As consumer appetite for bandwidth continues to grow, CPON will prove a scalable and extensible technology for fiber networks for the next 30 years.

Nobody knows the extent to which broadband speeds will continue to increase over the next 5-10 years, but service providers intend to be certain that their network solutions will be able to handle whatever is coming. With the announcement of the 10G Platform the cable industry has set a new target for future broadband speeds of at least 10 Gbps, with symmetry being a key component of that new speed target.

“I don’t want to have to share a pipe. The problem with ‘cable’ is shared pipes. If my neighbor is doing a bunch of stuff over the network, I get impacted too. With fiber I get speed and no shared pipes.”

Keeping Pace with Nielsen’s Law

Sep 15, 2016

The telecommunications industry typically uses Nielsen’s Law of Internet Bandwidth to represent historical broadband Internet speeds and to forecast future broadband Internet speeds. Mr. Nielsen predicted many years ago the high-end user’s downstream connection speed grows by approximately 50% compound annual growth rate (CAGR). In reality, actual peak service tiers offered by service providers over the years may be following something closer to 60% compound annual growth rate, as shown in the figure below.

Service providers invest billions of dollars in their access networks. Ideally, the deployed technology meets consumer demand for many years, allowing service providers to avoid costly upgrades before fully recovering their investments. In addition to technology longevity, service providers also like to see technology evolution, a next generation, to borrow an overused technology term, to ensure future consumer demands can be met by staying within the same technology family. Nowhere is the next generation moniker more prevalent than in the development of passive optical networking (PON) standards.
