Fiber to the Edge (FTTE), fiber to the telecom enclosure (FTTTE) or fiber to the zone (FTTZ),
is a
fiber to the x networking approach used in the enterprise building (hotels, convention centers, office buildings, hospitals, senior living communities,
Multi-Dwelling Units, stadiums, etc.). It is a standards-compliant
structured cabling
In telecommunications, structured cabling is building or campus cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems. Structured cabling components include twisted pair and opt ...

optical fiber
An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at ...
backbone network
A backbone or core network is a part of a computer network which interconnects networks, providing a path for the exchange of information between different LANs or subnetworks. A backbone can tie together diverse networks in the same buildin ...

equipment room directly to a
telecommunications enclosure (TE), access node, ONT, or media converter installed in a common space to serve a number of users or devices in a nearby area.
In other words,
fiber
Fiber (spelled fibre in British English; from ) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often inco ...
reaches directly from the
main distribution frame of a building out to the edge devices, eliminating or reducing the need for
intermediate distribution frames.
Implementation
Its implementation is based on the
TIA-569-B “Pathways and Spaces” technical standard, which defines the Telecommunications Enclosure (TE), and TIA/EIA-568-B.1 Addendum 5, which defines the cabling when a TE is used. The FTTE architecture allows for many media choices from the TE to the work area; it may be balanced twisted pair copper,
multi-mode optical fiber, or even wireless if an access point is installed in or near the TE.
Depending on the user’s needs, FTTE can be deployed in low-density or high-density configurations. A low-density system might use one or two inexpensive 8-port
Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 198 ...

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type o ...
es as an example (these switches have eight
10/100 Mbit/s Ethernet copper ports and one
1 Gbit/s Ethernet fiber uplink).
A high-density FTTE design might use commonly available 24- or 48-port switches (these switches are configured with one 1 Gbit/s uplink port per twelve
100BASE-TX user ports). This relatively high work area-to-backbone port ratio provides better performance than is typically provided to enterprise users. Both low and high-density FTTE architectures provide excellent performance in terms of bandwidth delivered to the work area.
Pros and cons
*Advantages
**Low Cost
**Non-blocking or low-blocking performance better supports
convergence
Convergence may refer to:
Arts and media Literature
*''Convergence'' (book series), edited by Ruth Nanda Anshen
*Convergence (comics), "Convergence" (comics), two separate story lines published by DC Comics:
**A four-part crossover storyline that ...
**Extremely flexible to deploy; supports Moves, Adds & Changes
**Enables consolidation of electronics into a centralized Telecommunications Room
**Allows the use of a variety of media from the TE to the user
*Disadvantages
**TE location is near the user and must be secured
