A Metropolitan Area Network (MAN) is a type of network that spans over an area
larger than a building. MANs are common at universities
and other places where the network
is too big to be considered as a Local Area Network
. MANs were originally meant to span a city
(which is the reason for its name), but large companies and universities also use this definition of their network, due to its size.
A MAN is commonly used for connecting LAN
s (i.e. connect the LANs of each building in a campus). These MANs frequently use optical fibre
s, and when used in a city, running cables through subway-tunnel
s is a popular solution.
NOTE: A MAN is not the same as a WAN!
