Introduction
In the last few years we have seen a great diffusion of internet access, mailing services,
video on demand and voice over IP. These new applications are characterized by a high band
consumption, thus requiring a high band for user applications in premises environment. The
multimode fibres are the physical medium recommended by different standard for local applications.
Lower total system cost
In a local network the cost of the transmitters is a substantial part of the total cost. With
multimode fibres, it is possible to use low cost transceiver, such as LEDs and VCSELs.
Easy splicing
Local networks allow many user to connect to the network simultaneously. This implies that a
simple and strong connection is required. With multimode fibre it is possible to obtain easy,
robust and low cost connections.
Compatibility
Multimode fibres are compatible with industry standards for fibre optics networks
protocol like FDDI, Ethernet, Fast Ethernet, Token Ring and ATM.
