Fiber to the telecom enclosure

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 system architecture that extends the optical fiber backbone network from the 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.
