Fiber to the telecom enclosure (FTTTE), also sometimes called fiber to the zone (FTTZ),
or fibre to the cabinet (FTTC) in the UK, 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 opti ...

optical fiber
An optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to ...
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 building ...

-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
Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 100 Gbit/s. Multi-mode fiber has a fairly large ...

Pros and cons
*Advantages
**Low Cost
**Non-blocking or low-blocking performance better supports

**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
