Fiber optic transceivers (also known as fiber switches) are Ethernet electrical interface and optical interface between the conversion. The fiber switch can be configured with one or more Ethernet electrical ports and one or more optical interfaces that extend the Ethernet transmission distance from 100 meters to 2 km (multimode fiber) or 120 km (single mode optical fiber). It can simply achieve multiple motherboard servers, repeaters, hubs, terminals and multiple terminals between the Internet. Using a mature exchange core, equipped with a variety of optical interface, support hot-swappable, with flexible, efficient, reliable and so on. Suitable for telecommunications, broadcasting, broadband networks, millions of high-definition video surveillance and other high-performance, high reliability of the network environment.
Fiber switch role and working principle: fiber switch is a high-speed network transmission relay equipment, it is more common than the use of fiber optic cable as a transmission medium. The advantages of optical fiber transmission is fast, anti-interference ability.
It is characterized by the use of high-speed fiber channel with the server network, or SAN (StorageAreaNetwork, storage area network) network internal components of the connection, so that the entire storage network has a very wide bandwidth for high-performance data storage The protection. In this SAN storage network, the key role is that we often hear the fiber switch (FCSwitch, also known as "Fiber Channel switch").
