100GbE – 100 Gigabit Ethernet
Computer networking technologies for transmitting Ethernet frames at rates of 100 gigabits per second (100 Gbit/s).
Provides each subscriber with their own fibre link to the network node switch, which links the local network to the Internet.
DWDM – Dense Wavelength Division Multiplexing
A technology that puts data from different sources together on an optical fibre, with each signal carried at the same time on its own separate light wavelength.
An optical fiber or optical fibre is a flexible, transparent fibre made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibres are used most often as a means to transmit light between the two ends of the fibre and find wide usage in fibre-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.
FTTB – Fibre To The Building/Business
A type of fibre-optic cable installation where the fibre cable goes to a point on a shared property and the other cabling provides the connection to single homes, offices or other spaces.
FTTC – Fibre to the Cabinet
A connectivity technology that is based on a combination of fibre optic cable and copper cable.
FTTH – Fibre to the Home
The delivery of a communications signal over optical fibre from the operator’s switching equipment all the way to a home.
FTTx – Fibre to the X
All possible optical fibre topologies from a telecom or cable carrier to its customers, based on the location of the fibre’s termination point.
GbE – Gigabit Ethernet
In computer networking, Gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second (1,000,000,000 bits per second).
GPON – Gigabit Passive Optical Network
A point-to-multipoint access network. Its main characteristic is the use of passive splitters in the fibre distribution network, enabling one single feeding fibre from the provider to serve multiple homes and small businesses.
MEF – Metro Ethernet Forum
A nonprofit international industry consortium, dedicated to adoption of Carrier Ethernet networks and services.
Metro WDM – Wavelength-division Multiplexing
In fibre-optic communications, WDM is a technology which multiplexes a number of optical carrier signals onto a single optical fibre by using different wavelengths of laser light. This technique enables bidirectional communications over one strand of fibre, as well as multiplication of capacity.
NFV – Network Functions Virtualization
Network functions virtualization (NFV) (also known as virtual network function (VNF)) offers a new way to design, deploy and manage networking services.
NG-PON2 – Next-Generation Passive Optical Network 2
A 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.
SDN – Software-Defined Networking
An umbrella term encompassing several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data centre.
XGS-PON – 10-Gigabit-capable Symmetric Passive Optical Network
A higher bandwidth, symmetric version of GPON.
