The Connection Ways of Fiber Media Converter

Fiber Optic Media Converter is a short twisted-pair electric signals and optical signals over long distances to swap the Ethernet transmission media conversion unit, also known as the photoelectric converter at many places. Products commonly used in Ethernet cable can't cover, optical fiber must be used to extend the transmission distance of actual network environment, and usually located in broadband metropolitan area network access layer of the application.

In traditional Ethernet, the medium of connection is the double stranded wire. The limits of twisted-pair transmission distance is about 200 meters, so short transmission distance of restricting the development of network, twisted pair is strongly influenced by electromagnetic interference at the same time, it also makes data communication quality is affected by the larger. The use of fiber optic media converter is used to change the connection medium in Ethernet to optical fiber. Optical fiber has low loss and high electromagnetic interference, in the network transmission distance from 200 m to 2 kilometers or even dozens of kilometers, even in the hundreds of kilometers, at the same time, also make the quality of data communication has greatly improved. He makes the connection between servers, relays, hubs, terminals and terminals more simple.

In practical applications, the fiber optic media converter basically has the following three basic connection mode: a circular, circular backbone of backbone network is to use the SPANNING TREE characteristics to build the backbone of the metropolitan area within the scope, this structure can be transformed into the reticular structure, suitable for high density on metropolitan area network at the center of the village, form the core backbone network fault tolerance. The loop backbone network supports IEEE 1Q and ISL network features to ensure that most mainstream backbone networks, such as vlans, TRUNK, etc., are compatible. The circular backbone network can form broadband virtual private networks in finance, government, education and other industries.

2, chain backbone chain backbone network using chain form the backbone of the connection can save a lot of light, suitable for the edge of the city and suburban county district construction of high bandwidth and low price of backbone network, the model can be used in the highway at the same time, such as oil, transmission line environment. Chain-shaped backbone support for ieee802.1q and ISL network characteristics, to ensure compatibility with most of the backbone network, can provide financial, government, education and other industries to form a broadband virtual private network. The chain backbone is a multimedia network that can provide images, voice, data, and real-time monitoring.

Three, user access system users access the system using 10 MBPS / 100 MBPS adaptive and 10 MBPS / 100 MBPS automatic conversion function, can join any client devices, don't need to prepare a variety of fiber optic transceivers, can provide a smooth upgrade scheme for network. At the same time using half duplex/full duplex adaptive and half duplex/full duplex automatic conversion function, can be in the client configuration of cheap half duplex HUB, several dozen times the client of the network to reduce costs, improve the competitiveness of the network operators. At the same time, the device's built-in exchange core increases the transmission efficiency of the connected device, reducing network broadcast, controlling the flow, detecting transmission failure.
