This, along with newer technologies – such as
DOCSIS 3, channel bonding, and VDSL2 (the
latter of which can wring more than 100 Mbit/s
out of plain, unshielded twisted-pair copper
under normal conditions, out of a theoretical
maximum of 250 Gbit/s at 0.0m from the VRAD) –
and more sophisticated provisioning systems –
such as FTTN (fiber [optic cable] to the node) and
FTTP (fiber to the premises, either to the home or
provisioned with Cat 5e cable) – can provide
downstream speeds to the mass-market
residential consumer in excess of 300 Mbit/s and
upload speeds in excess of 100 Mbit/s with no
specialized equipment or modification (Verizon
FiOS highest tier).

Digital subscriber line - Basic technology
Because of this, phone companies
endeavor to remove load coils on
copper loops that can operate without
them, and by conditioning other lines
to avoid them through the use of fiber
to the neighborhood or node (FTTN).

Internet access - Fiber to the home
Fiber-to-the-home (FTTH) is one
member of the Fiber-to-the-x (FTTx)
family that includes Fiber-to-thebuilding or basement (FTTB), Fiberto-the-premises (FTTP), Fiber-to-thedesk (FTTD), Fiber-to-the-curb
(FTTC), and Fiber-to-the-node (FTTN)

Fiber to the x
1
Fiber to the x (FTTX) is a generic term for
any broadband network architecture using
optical fiber to provide all or part of the
local loop used for last mile
telecommunications. The term is a
generalization for several configurations of
fiber deployment, ranging from FTTN (fiber
to the neighborhood) to FTTD (fiber to the
desktop).

Fiber to the x - Definitions
FTTN / FTTLA (fiber-to-the-node, neighborhood, or -last-amplifier): Fiber is
terminated in a street cabinet, possibly
miles away from the customer premises,
with the final connections being copper.
FTTN is often an interim step toward full
FTTH and is typically used to deliver
advanced triple-play telecommunications
services.

Fiber to the x - Definitions
1
FTTC / FTTK (fiber-to-the-curb/kerb, closet, or -cabinet): This is very similar
to FTTN, but the street cabinet or pole is
closer to the user's premises, typically
within 1,000 feet (300 m), within range
for high-bandwidth copper technologies
such as wired ethernet or IEEE 1901
power line networking and wireless WiFi technology. FTTC is occasionally
ambiguously called FTTP (fiber-to-thepole), leading to confusion with the
distinct fiber-to-the-premises system.

Fiber to the x - Definitions
1
To promote consistency, especially when
comparing FTTH penetration rates
between countries, the three FTTH
Councils of Europe, North America, and
Asia-Pacific agreed upon definitions for
FTTH and FTTB in 2006, with an update in
2009 and another in 2011. The FTTH
Councils do not have formal definitions for
FTTC and FTTN.

Fiber to the x - Ethernet point-to-point
1
Point-to-point protocol over Ethernet (PPPoE)
is a common way of delivering triple- and
quad-play (voice, video, data, and mobile)
services over both fiber and hybrid fibercoaxial (HFC) networks. Active PPPoE uses
dedicated fiber from an operator's central
office all the way to the subscribers' homes,
while hybrid networks (often FTTN) use it to
transport data via fiber to an intermediate
point to ensure sufficiently high throughput
speeds over last mile copper connections.

Fiber to the x - Fiber to the node
1
Fiber to the node or neighborhood (FTTN),
sometimes identified with and sometimes
distinguished from fiber to the cabinet
(FTTC), is a telecommunication
architecture based on fiber-optic cables
run to a cabinet serving a neighborhood
https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
Fiber to the x - Fiber to the node
FTTN allows delivery of broadband
services such as highspeed internet.
Highspeed communications protocols
such as broadband cable access
(typically DOCSIS) or some form of
digital subscriber line (DSL) are used
between the cabinet and the
customers. The data rates vary
according to the exact protocol used
and according to how close the
customer is to the cabinet.

Fiber to the x - Fiber to the node
Unlike FTTP, FTTN often uses existing
coaxial or twisted-pair infrastructure to
provide last mile service and is thus less
costly to deploy. In the long term, however,
its bandwidth potential is limited relative to
implementations that bring the fiber still
closer to the subscriber.

Fiber to the x - Fiber to the curb (also known as fiber to the cabinet)
1
FTTC is subtly distinct from FTTN or
FTTP (all are versions of fiber in the
loop). The main difference is the
placement of the cabinet. FTTC will
be placed near the "curb", which
differs from FTTN placed far from the
customer, and FTTP placed directly at
the serving location.

FTTN is currently used by a number of
multiple-service operators to deliver
advanced triple-play services to
consumers, including AT&T in the United
States for its U-Verse service, Deutsche
Telekom in Germany, Swisscom,
Belgacom in Belgium, and Canadian
operators Telus and Bell Canada. It is
seen as an interim step towards full FTTH
and in many cases triple-play services
delivered using this approach have been
proven to grow subscriber numbers and
ARPU considerably.

TekSavvy - Digital subscriber line (DSL) Internet
On March 20, 2013, TekSavvy added a 50
Mbit/s tier, the fastest FTTN tier that Bell
started offering a month earlier. TekSavvy
offers the same FTTN DSL speeds available
from Bell. The only exceptions are that for
the slowest plans, 6 Mbit/s regular DSL and 7
Mbit/s FTTN DSL is sold by TekSavvy instead
of Bell's 5 Mbit/s plans. All plans offer a
choice between 300 GB or unlimited Internet
access, while the 6 and 7 Mbit/s plans offer a
lower-priced 75 GB option.
