Metropolitan area network is a computer communication network established within a city, referred to as MAN. It is a broadband local area network. Due to the local area network technology with active switching elements, the transmission delay in the network is small, and its transmission medium mainly uses optical cables, and the transmission rate is above 100Gbit/s. An important use of MAN is for...
