A fiber optic cable assembly with SC APC connectors, as commonly used to link optical network terminals to passive optical networks. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment.
It is commonly used to implement the link to the customer (the last kilometre, or last mile) of fibre-to-the-premises services. [2] [3] GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which Ethernet frames are converted to an optical signal, as well as the parameters of that signal.
An Alcatel-Lucent OLT used by the French operator CityPlay OLT and ONU in fiber optic network. 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:
Passive optical networks are used for the fibre-to-the-home or fibre-to-the-premises last mile with splitters that connect each central transmitter to many subscribers. The 10 Gbit/s shared capacity is the downstream speed broadcast to all users connected to the same PON, and the 2.5 Gbit/s upstream speed uses multiplexing techniques to prevent ...
An optical network terminal mounted to the outside of a building, with the cover open. In fiber-to-the-premises systems, the signal is transmitted to the customer premises using optical fiber technologies. Unlike many conventional telephone technologies, this does not provide power for premises equipment, nor is it suitable for direct ...
Fiber to the x (FTTX; also spelled "fibre") or fiber in the loop 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. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone ...
Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks.These include limited range local-area networks (LAN) or wide area networks (WANs), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks.
ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links, able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of optical channels carrying client signals. [1]
