The system supports high bandwidth demands from applications like IPTV, Internet video, HD programming, and mobile video by increasing the speeds over existing fiber. Typically, increasing the speeds from 10G to 40G to 100G entails trade-offs such as shortening the distance of each network segment or increasing optical dispersion because of the ...
FICON (Fibre Connection) is the IBM proprietary name for the ANSI FC-SB-3 Single-Byte Command Code Sets-3 Mapping Protocol for Fibre Channel (FC) protocol.It is a FC layer 4 protocol used to map both IBM's antecedent (either ESCON or parallel Bus and Tag) channel-to-control-unit cabling infrastructure and protocol onto standard FC services and infrastructure.
Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
The Post Office or BT system historically used PW and R, optionally followed by a Region and/or Area code, followed by a number of digits between 4 and 6 for rented, analogue private lines. A Region code might have been LR for London Region or ER for Eastern Region, and for an Area L/NW for North West London or CB for Cambridge.
Fiber-optic communication remains the medium of choice for Internet backbone providers for several reasons. Fiber-optics allow for fast data speeds and large bandwidth, suffer relatively little attenuation — allowing them to cover long distances with few repeaters — and are immune to crosstalk and other forms of electromagnetic interference.
Greenlight was founded in 2011 by Mark Murphy and began offering 1 Gigabit fiber optic internet service in 2012. [1] The service began mostly confined to areas east of the Genesee River due to financial constraints with building new fiber optic lines particularity in Rochester's suburbs and getting permission the various towns and from Rochester Gas and Electric to use their existing poles.

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.
