along with the development of the information network, the requirements of the bandwidth are growing. the main medium for connection in traditional ethernet network is twisted-pair, of which the maximum transmission distance is about 100 meters. the transmission distance is so short that the development of the network is restricted, and also quality of the data communications is influenced.
the application of optical media converter uses optical cable as connection medium in ethernet network. low-loss and high anti-electromagnetic interference capability of the optical cable, extend the transmission distance of a network from 200m to 2km or decade kilometers, or even a hundred kilometers, at the same time improving the quality of data communication.。 that makes the connection between repeater、hub、terminal and terminal easier and simple.
user access network makes use of network management function of optical media converter, to implement centralized management to each separate user.
10mbps/100mbps adaptive character and 10mbps/100mbps auto-switch function of optical media converter，supply enough bandwidth to users.
besides, application of the link failure alert (lfa) function can substitute centralized network management function by mutual supervising in point-to-point transmission, which can decrease the cost of access.
in addition, by using halt/full duplex adaptive and auto-negotiation function, a low-cost half duplex hub can be figured to user end, which greatly decrease the cost of network building at user end and improve the competence of carriers.
