FTTP

Fiber optic cable to the premises (FTTP) defines a fiber optic cable connection all the way to a home, business, school, government office or other entity.  The FTTP network is connected to other fiber networks over long haul fiber networks to other cities, states, and continents.  FTTP is the same as FTTH, (fiber to the home).

 

FTTP has always been inevitable, because bandwidth utilization and therefore demand, continually increases and only fiber optic cable has fundamentally unlimited bandwidth capacity.  Fiber's bandwidth is also symmetrical, equal in upload and download capacities.

 

Coax cable (video cable broadband) and telephone wires (DSL broadband) are copper wire based infrastructures, already at their upper limits of bandwidth capacity; a small fraction of fiber optic cable’s capacity.  Coax and DSL broadband are non-symmetrical in that their upload capacities are far smaller than the download capacities, which inhibit present and future robust interactive activities.  The bandwidth capacity of coax and DSL rapidly erodes with the distance traveled over their cooper wire infrastructure.  This is similar to the amount of force it takes to push an object through a pipe.  The further away from the starting point, the more force it takes to maintain the speed of the object within the pipe and to push it further down the pipe.

CRITICAL COMMUNITY INFRASTRUCTURE

FTTP is a critical community infrastructure, no different than electricity, water, and transportation networks.  The national broadband plans of the United States and numerous industrialized nations have extensively documented the need for FTTP networks.  The broad economic development opportunities and societal benefits of FTTP networks have been well defined and yet, are likely far greater than currently understood.

 

Communities without a FTTP infrastructure will be at a disadvantage relative to serving their citizens, industry, government, schools, health care providers, and driving their economic development.

Data Traffic

An understanding of bandwidth demand can be gained from the historical and projected growth of data traffic, also called network traffic.  Data traffic represents emails, files, music, pictures, video, and all other applications (data) transferred over the Internet.

     •  In 1992, the global data traffic was 100 Gigabytes per day

     •  In  2017, global data traffic is projected to be 35,000 Gigabytes per second, an increase of

more than 30 million times in 25 years

 

The projected data traffic of 2017 represents all the data contained in 362 billion DVDs.  Put another way, all the data traffic from 1984, the beginning of the Internet, to 2012 is estimated at 1.2 Zettabytes.  In 2017, global data traffic will exceed 1.4 Zettabytes, greater than 28 years of total data traffic, in a single year.

 

Though the amount of data traffic is astounding, it would far greater if FTTP networks were widely deployed.  Coax and DSL infrastructures are inhibiting not only data traffic, but development of advanced applications and services in health care, education, media, teleconferencing, cloud computing, big data, and all areas that require the bandwidth capacity of FTTP networks.

Data traffic statistics are from Cisco Corporation's "The Zettabyte Era—Trends and Analysis."

FTTP NETWORKS AND MOBILE NETWORKS

Fiber networks have fundamentally unlimited bandwidth capacity and mobile and wireless have finite bandwidth capacity.  Mobile and wireless networks, such as Wi-Fi have low bandwidth capacity, relative to fiber optic cable, due to the limited radio spectrum, which defines bandwidth capacity.  All usable radio spectrum has been allocated for television, radio, national defense, GPS and many other applications. Additional spectrum can be added to mobile networks by taking spectrum from those to whom it had been previously allocated.

 

FTTP networks decrease the build out and operational costs for mobile networks and facilitate the convergence of separate consumer, public safety, and homeland security tower and networks systems into a single tower and network system.  The bandwidth capacity and operations center of the FTTP networks enable advanced applications and services for mobile and Wi-Fi networks.

 

Current 4G mobile network towers and future generations of mobile ("XG") are connected to fiber networks to provide connectivity (backhaul) to the Internet.  As radio spectrum (bandwidth capacity) is highly limited, mobile data traffic is offloaded to fiber networks.  Wi-Fi networks within a city, business or residence also offload their data traffic to fiber networks.
