Downstream traffic in active (top) vs. passive optical network. A passive optical network consists of an optical line terminal (OLT) at the service provider's central office (hub), passive (non-power-consuming) optical splitters, and a number of optical network units (ONUs) or optical network terminals (ONTs), which are near end users.
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.
G.987: 10-Gigabit-capable passive optical network (XG-PON) systems: Definitions, Abbreviations, and Acronyms, 2010. G.987.1 : General requirements of 10G-PON systems (approved 2010-01-13) . Includes examples of services, user network interfaces (UNIs) and service node interfaces (SNIs), as well as the principal deployment configurations that ...
Following the publication of 40 Gbps NG-PON2 in July 2015, standardization activities turned to higher speed PON. [4] In November 2016, the Full Service Access Network (FSAN) Group released the Standards Roadmap 2.0 which indicated the development of "future optical access systems" with peak transmission rates above 10 Gbps.
Numbering plan areas and area codes of Texas with numbering plan area 682/817 highlighted. Area codes 817 and 682 are telephone area codes in the North American Numbering Plan (NANP) in the U.S. state of Texas. The service area comprises the city of Fort Worth and most of the western portion of the Metroplex.
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.
New Hampshire's Attorney General on Tuesday named a Texas telecom company as the source of an apparently AI-generated robocall impersonating President Joe Biden
In the United States, the industry decided in 1947 to unite all local telephone networks under one common numbering plan with a fixed length of ten digits for the national telephone number of each telephone, of which the last seven digits were known as the local directory number, or subscriber number.
