PON Passive Optical Network - is a telecommunications network that uses point-to-multipoint fibre to the end-points in which unpowered optical splitters are used to enable a single optical fibre to serve multiple end-points.  
RGW Residential Gateway is the technical name for the customer's modem. The RGW is customer premises equipment. It allows the connection of a Local Area Network (LAN) to a Wide Area Network (WAN) otherwise known as the internet.  
UFB Ultra Fast Broadband - another name for Fibre Broadband  
UFF Ultra Fast Fibre (a Local Fibre Company in Waikato)  
VoF/VOF Voice over Fibre - When your landline phone makes and receives calls via the fibre cabling connected to your premises instead of copper wire. This is different than VOIP because the call does not actually travel through the internet. The fibre cables connected to your house are just one point on the journey. The call will still travel through the normal phone network just like a phone call made via copper wire.  
VOIP Voice Over Internet Protocol - The delivery of voice communication via the internet. A good example of this is video chat applications like Skype and Oovoo  
WAN Wide Area Network. A telecommunications network or computer network that extends over a large geographical distance. Wide area networks often are established with leased telecommunication circuits. A leased telecommunication circuit is a private telecommunications line between two or more locations provided in exchange for a monthly rent. For example, Chorus owns and rents out telecommunications lines to Retail Service Providers like Spark.
