Fiber Optic Switch Function and Working Principle
Fiber optic switches provide the capability to cascade many switches into a large-scale Fabric. By connecting one or more ports of two switches, all ports connected to the switches can see a unique image of the network, and any node on this Fabric can communicate with other nodes.
In essence, by cascading switches, a large, virtual switch with distributed advantages can be established, and it can span very large distances. A Fabric built from multiple switches appears as a single-switch Fabric, where all ports on the switches can view and access all other ports on the Fabric just as they would access a local switch. A unified name server and management service allow viewing and modifying all Fabric information through a single interface.
An important factor in creating a distributed Fabric is obtaining bandwidth for inter-switch connections. The effective rate between any two ports is affected by the effective bandwidth of the inter-switch connections, and multiple inter-switch connections may be required to maintain the necessary bandwidth. Workgroup Fibre Channel switches are numerous and more versatile.
Users can use workgroup switches for a variety of purposes, but the most common application area is small SANs. Such switches can be connected via inter-switch links to provide a greater number of ports. Inter-switch links can be created on any port of a Fibre Channel switch. However, if multi-vendor products are planned, interoperability must be ensured.
The UT series multi-port media converter (also known as a fiber optic switch) converts between Ethernet electrical interfaces and optical interfaces. A fiber optic switch can be configured with one or more Ethernet electrical ports and one or more optical interfaces, extending the Ethernet transmission distance from 100 meters over copper cable to 2 kilometers (multimode fiber) or 120 kilometers (single-mode fiber). It can simply achieve interconnection between multiple motherboard servers, repeaters, hubs, terminals, and multiple terminals. It adopts a mature switching core, is equipped with multiple fiber interfaces, supports hot-swapping, and features flexibility, high efficiency, and reliability. It is suitable for network environments requiring high performance and high reliability, such as telecommunications, broadcasting, broadband networks, and megapixel HD video surveillance.
Fiber optic switch function and working principle: A fiber optic switch is a high-speed network transmission relay device that uses fiber optic cable as the transmission medium compared to ordinary switches. The advantages of fiber transmission are high speed and strong anti-interference capability.
Its characteristic is the use of high-speed Fibre Channel to connect server networks or internal components of SAN (Storage Area Network) networks, giving the entire storage network very wide bandwidth and ensuring high-performance data storage. In such SAN storage networks, the key role is played by the fiber optic switch (FC Switch, also known as "Fibre Channel switch") that we often hear about.
