Like a cable TV network, Metropolitan Area Network Diagram typically spreads throughout a city. It can be Ethernet, Token-ring, ATM, or FDDI. A MAN, like a WAN, is made up of interconnected LANs.Metropolitan Area Network Diagrams are typically more efficient than WANs because data does not require long distances. Instead of being managed by a single company, MANs typically combine the networks of multiple organizations. A metropolitan area network (MAN) is a computer network that connects computers in a metropolitan area, which can be a single large city, multiple cities and towns, or any large area with numerous buildings. The majority of MANs use fiber optic cables to connect LANs. A MAN is frequently powered by "dark fiber" — previously unused fiber optic cables.
