This is a list of very-high-bit-rate digital subscriber line (VDSL) and very-high-bit-rate digital subscriber line 2 (VDSL2) deployments.. The term VDSL can either refer specifically to ITU-T G.993.1 (first generation VDSL, officially abbreviated as "VDSL", unofficially also called "VDSL1"), or may be used as an umbrella term for both ITU-T G.993.1 and ITU-T G.993.2 (second generation VDSL ...
Transparent LAN service between two sites has been successful, but multi-point transparent LANs have been problematic due to the difference in architecture between the broadcast-based Ethernet and the carrier's point-to-point network. The VPLS (a type of VPN) standard was developed to resolve the problem using IP and MPLS routers.
Ethernet Virtual Private LAN or E-LAN: a multipoint service connecting a set of customer endpoints, giving the appearance to the customer of a bridged Ethernet network connecting the sites. Ethernet Virtual Private Tree or E-Tree : a multipoint service connecting one or more roots and a set of leaves, but preventing inter-leaf communication.
Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint to multipoint communication over IP or MPLS networks. It allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires .

The WAN PHY operates at a slightly slower data-rate than the local area network (LAN) PHY. The WAN PHY can drive maximum link distances up to 80 km depending on the fiber standard employed. The WAN PHY uses the same 10GBASE-S, 10GBASE-L and 10GBASE-E optical PMDs as the LAN PHYs and is designated as 10GBASE-SW, 10GBASE-LW or 10GBASE-EW.
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
A standardized variant of 10 Gigabit Ethernet, called WAN PHY, is designed to inter-operate with OC-192 transport equipment while the common version of 10 Gigabit Ethernet is called LAN PHY (which is not compatible with OC-192 transport equipment in its native form). The naming is somewhat misleading, because both variants can be used on a wide ...
