SD12-SK Application Field and Working PrincipleThe SD12-SK is a digital optical fiber telecommunications switch system developed by CET Group, a leading international telecom vendor. The SD12-SK is a single-site distributed control architecture system applied for medium-long distance optical fiber network applications. It is designed for small-scale to medium-sized networks for telecommunication service providers and large enterprises. It is often used for providing services such as Ethernet, ATM, FDMA, WDM, and IP.Application FieldThe SD12-SK switch system supports a wide range of optical layers, making it ideal for medium-long distance optical fiber networks. It supports all fiber types, including single-mode, multi-mode, single-strand, and dual-strand fiber. The system can also be used for high-speed data connections, ensuring reliable data delivery at long distances. In addition, it is suitable for establishing secured private networks for enterprises and government agencies, as well as for offering high-efficiency data transmission services. In this way, the system is applicable for a wide range of medium-long distance network projects.Working PrincipleThe working principle of the SD12-SK system is based on its distributed control architecture. This architecture consists of a master switch and a set of slave switches. The system is based upon a hierarchical mesh topology, with the master switch as the superordinate node and the slaves acting as subordinate nodes. Each slave switch is connected to the master switch by one or more fibers, and the master switch is the ultimate control center for the entire network.The master switch is responsible for managing the layer configuration, connection establishment, service delivery, and system maintenance for the system. It can also be used as a medium for interconnection between different services and locations. The slave switches, on the other hand, are responsible for passing the data traffic information to the master switch and for the initialization of the system, while the switches themselves only transmit data packets to the designated destinations based on the information received from the master switch. The system also supports multiple parallel links, allowing for load balancing and improved performance.ConclusionThe SD12-SK system is a highly reliable optical fiber telecommunications switch system designed to provide efficient and secure network connections for medium-long distance networks. It can be used for a variety of applications and offers many features, such as distributed control architecture, hierarchical mesh topology, and multiple parallel links. As such, it is an ideal choice for medium-long distance network projects.
