10G-PON
10G-PON (also known as XG-PON or G.987) is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s (gigabits per second) over dark fiber.An optical network terminal (ONT) is an ONU that functions as a demarcation point servicing a single subscriber; e.g., a dwelling or office.ONU devices supply Ethernet and possibly other services to the users, either directly (by bridging) or through a gateway device such as a residential gateway, firewall, and/or router, POTS, CATV signals to buildings wired for RF video, and some may even be compatible with the emerging G.hn home networking standard.The ONU receives the downstream data from the Internet or private networks, and also uses time slots allocated by the OLT to send the upstream traffic in burst-mode.Locating OLTs in outside plant cabinets may be an option for reach extension as a way to minimise the number of central offices covering low population density areas."An Optical Distribution Network (ODN) being installed today will likely need to support four or more generations of PON over its expected 30 – 40 year life...
