Metro-Ethernet is generally the term used to describe Ethernet used as a
WAN connection or as a point to point connection. There was at one time
the concept of a MAN (Metro Area Network) but "metro" ethernet is now
available in more scenarios than that described. The connectivity can be
over fiber or copper and the speed delivered can be as low as a few mbps
but commercially available offerings normally start at 5-10 mbps. On the
high end its possible to get gigabit and faster connections in certain
areas.

VPLS stands for Virtual Private Lan Services. This an umbrella technology
that allows for the bridging of layer 2 traffic across various layer 2 & 3
networks. This is generally used as a replacement for a point to point
metro ethernet (or other) connection.
