Metro fiber is a fiber optic network which connects several enterprises in a metropolitan area providing a high-speed broadband connection˳ High-speed data is transmitted as light impulses˳ These fibers are often leased out by providers to other companies˳
Metro fiber is a relatively newer technology which is used to connect buildings in a large metropolitan area over the internet, like connecting multiple computers in a single building˳ In a metropolitan area, metro fiber is used to link central offices˳ In a fiber optic network, this fiber is used for high-speed data transmission through fiber optic lines in the form of light pulses˳
To simplify the functioning of a metro fiber network, consider a hypothetical situation, where all business enterprises and even individual consumers are making use of a single network˳ These networks would then join with even larger networks and the metropolitan area would be connected by a single large network˳ Metro fiber is used for high-speed broadband connection across several enterprises in a metropolitan area˳ The buildings that it connects are known as ‘lit’ or ‘on-net’ buildings˳ With speeds up to 10, 100, or 1000 Mbps, it enables faster access to internet and data transfer for clients, a major way forward from the traditional bandwidth˳ This fiber enables one to meet high data needs of multi-site business enterprises˳
A highly favorable alternative to traditional internet connections, these fibers are particularly beneficial for data and multimedia transfers˳ Business enterprises stand to gain the maximum from this technology by using it for increasing their productivity and thus get higher revenues˳
The providers of metro fiber networks often lease out unused fibers to other companies˳ These unused fibers are called dark fibers˳ These fibers are leased out to enterprises for establishing optical connections in their region˳ For example, large business houses leasing out their connections, phone companies connecting central offices, etc˳ If a local cable company leases out network connections to a television company, then the television company can directly transmit signals to the cable company, thus relaying crystal clear signals˳
Networks using this fiber can transmit signals over a range of approximately 200 kilometers, though most connections are confined in much shorter area like a metropolitan area˳ Most connections are made within a span of 100 kilometers and do not require the use of an optical amplifier, except when the coupling loss is very high˳ The optical amplifiers do not permit operation of light wavelength outside the available band of the optical amplifier˳
The metro fiber technology has become a revolution of sorts˳ It is connecting people, increasing the productivity of business enterprises and binding several institutions in one network˳ With speeds of 155 Mbit/s up to 10 Gbit/s, a complete channel can be leased out through this fiber network with data being transmitted at whatever speed you want˳
