Mapleland Fiber Network (MFN) Essay

The city of Mapleland, Oregon, which owns and operates its own power utility, built a fibre-optic meshwork to monitor power meters at residents homes. The network is called Mapleland Fiber cyberspace (MFN). Because MFN had more capacity than was needed to monitor meters, the city expanded its serve to offer rise to power to the network for citybusinesses. The businesses use the network to communicate with each other and to access the Internet.

In the city neighborhoods, hybrid fiber-coax nodes crop coax cabling to each street and into the homes for cable modem Internet access.The MFN backbone c onsists of a fiber-optic Gigabit Ethernet network that runs through the city in a ring topology. The fiber-optic ring connects the hybrid fiber-coax nodes that bring coax cabling to each neighborhood. Also connected to the ring are sextette data routers. Each router links one or more Mapleland businesses to MFN via dewy-eyed point-to-point connections. At the business, the fiber-optic network enters the building and connects to a media converter. A UTP cable connects to the media converter and typically to a 100-Mbps Ethernet switch. The switch links the businesss computers and servers in a star opology via UTP cabling.1.
