Inter-Provincial/Inter-City Metropolitan Area Network Overall Solution

Overview

From a transmission perspective, carrier networks can be divided into: backbone networks, metropolitan area networks (MAN), and access networks.  

The carrier metropolitan area network serves as a critical node for data aggregation and network access within the carrier's infrastructure.  

A typical application of MAN is the broadband metropolitan area network, which is a high-bandwidth, multifunctional, and multi-service access multimedia communication network built on IP and ATM telecommunication technologies, using optical fiber as the transmission medium to integrate data, voice, and video services within urban areas.
