Fiber Media Converter System

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.

 There are three basic connection mode for optical media converter in practical application: 

1,user access network

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.

2,ring trunk network

Ring trunk network make use of the characters of SPANNIGN TREE to build trunk network in metropolitan area. This structure can be changed to reticulation structure, which is applied to high-density center community in metropolitan area, to form a core trunk network. 

It supports IEEE.1Q and ISL, to ensure being compatible with the most mainstream backbone network, such as VLAN,TRUNK function, etc. Ring trunk network can construct dummy private network for the line of finance,government,education, etc.

3,chain network structure

Chain network structure makes use of chain connection, saving lots of backbone optical cable. It is adapted to construct high bandwidth and low price backbone network. This mode can also used in freeway,oil transmitted line and electric transmitted line.

It supports IEEE.1Q and ISL, to ensure being compatible with the most mainstream backbone network, such as VLAN,TRUNK function, etc. Ring trunk network can construct dummy private network for the line of finance,government,education, etc.

It is a multimedia network which can supply centralized transmission of image,voice,data and real-time supervising.
