XFP Transceiver Connection 【Topology】

The role of the XFP transceiver is to change the connection medium in Ethernet to fiber. Fiber transmission on the signal there is low loss, high resistance to electromagnetic interference. Can be the network signal transmission distance from 200 meters to 2 km or even tens of kilometers, and even hundreds of kilometers at the same time, but also to ensure the quality of data communications. He makes the switches, servers, repeaters, hubs, computers between the Internet more quickly and easily. XFP transceiver in the actual use of the process, the general use of the following two basic connection: First, the chain network structure The chain-type backbone network can save a large number of backbone light quantity by chain connection, which is suitable for constructing high-bandwidth and low-cost backbone network at the edge of the city and the suburbs. The model can also be used in highway, oil and transmission Lines and other environments. Chain backbone network support for IEEE802.1Q and ISL network features, can guarantee compatible with the vast majority of the backbone network, for the financial, government, education and other industries set up broadband virtual private network. Chain backbone network is able to provide image, voice, data and real-time monitoring of integrated transmission of multimedia networks. Second, the ring network structure The backbone backbone network is constructed by using SPANNING TREE to construct the backbone of the metro area. This structure can be deformed into a mesh structure, which is suitable for the high density central area on the metropolitan area network, forming a fault-tolerant core backbone network. Ring backbone network support for IEEE.1Q and ISL network features can guarantee compatibility with most mainstream backbone networks, such as cross-switch VLAN, TRUNK and other functions. Ring backbone network for the financial, government, education and other industries set up broadband virtual private network.
