An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: to perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical ...
A fiber pigtail is a single, short, usually tight-buffered, optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber in the trunk "breaks out" the multi ...
LC (top) and ST (bottom) optical fiber connectors, both with protective caps in place. An optical fiber connector is a device used to link optical fibers, facilitating the efficient transmission of light signals. An optical fiber connector enables quicker connection and disconnection than splicing.
Breakout-style fiberoptic cable (also called breakout cable or fanout cable), is an optical fiber cable containing several jacketed simplex optical fibers packaged together inside an outer jacket. This differs from distribution-style cable , in which tight-buffered fibers are bundled together, with only the outer cable jacket of the cable ...
A cable composed of glass fiber optic strands connects from the main service cables along a street to the subscribers house, and terminates on what is known as an Optical Network Termination unit (ONT). The ONT has a data port where cabling from the street connects to a point on the house, and these individual cables are typically installed by ...
ANSI/TIA-568 is a technical standard for commercial building cabling for telecommunications products and services. The title of the standard is Commercial Building Telecommunications Cabling Standard and is published by the Telecommunications Industry Association (TIA), a body accredited by the American National Standards Institute (ANSI).
Each outlet is then patched into a network switch (normally also rack-mounted) for network use or into an IP or PBX (private branch exchange) telephone system patch panel. Lines patched as data ports into a network switch require simple straight-through patch cables at each end to connect a computer.
Australia's National Broadband Network uses the term network termination device or NTD. A smartjack is a type of NID with capabilities beyond simple electrical connection, such as diagnostics. An optical network terminal (ONT) is a type of NID used with fiber-to-the-premises applications.
