Passive optical networks were first proposed by British Telecommunications in 1987. [8]Two major standard groups, the Institute of Electrical and Electronics Engineers (IEEE) and the Telecommunication Standardization Sector of the International Telecommunication Union (ITU-T), develop standards along with a number of other industry organizations.
NG-PON2 (also known as TWDM-PON), Next-Generation Passive Optical Network 2 is a 2015 telecommunications network standard for a passive optical network (PON). The standard was developed by ITU and details an architecture capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.
The primary optical transmitter, known as the optical line terminal (OLT), is housed within the central office of the telecommunications operator. A laser in the OLT injects photons from the central office into a glass-and-plastic fiber-optic cable that terminates at a passive optical splitter.
You are free: to share – to copy, distribute and transmit the work; to remix – to adapt the work; Under the following conditions: attribution – You must give appropriate credit, provide a link to the license, and indicate if changes were made.
A passive optical network (PON) is a point-to-multipoint FTTP network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve up to 128 customers. A PON reduces the fiber and central office equipment required compared with point-to-point architecture.
Ethernet passive optical network (EPON) is a technology for fiber to the x access networks, with millions subscriber lines.In response to rapid growth, the SIEPON project was formed in 2009 to develop system-level specifications, targeting "plug-and-play" interoperability of the transport, service, and control planes in a multi-vendor environment.
The 10 Gbit/s Ethernet Passive Optical Network standard, better known as 10G-EPON allows computer network connections over telecommunication provider infrastructure. The standard supports two configurations: symmetric, operating at 10 Gbit/s data rate in both directions, and asymmetric, operating at 10 Gbit/s in the downstream (provider to customer) direction and 1 Gbit/s in the upstream ...
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.
