SCN-2662SC

SCN-2662SC is a type of optical transport network (OTN) service interface equipment developed by Shenzhen Hengzhuo Xinke Network Technology Co., Ltd., which provides comprehensive network optical fiber access service functions, including access, transmission, protection switching, clock synchronization, OAM monitoring, alarm indication, etc. It supports various switching functions such as 3R regeneration, MPLS-TP, VLAN, multicast and transparent transmission, and can provide customers with 10G/100G/400G channel services.

SCN-2662SC is a new type of high-performance interface equipment for long-distance access on the access side of the telecommunications core network. It is suitable for the construction of last-mile access of FTTC/FTTH in the access side of the metropolitan area network core network. SCN-2662SC is mainly composed of system control unit, user line module, service board, power supply and other components.

The system control unit supports various functions such as optical performance monitoring, alarm indication and system status monitoring. The user line module is the front-end interface of the service unit, which is responsible for the bidirectional transmission of optical signals. Service board is responsible for signal processing, function switching, etc. The power supply is used to supply power to the system and its components.

SCN-2662SC mainly applies to Ethernet access, cellular backhaul, and other scenarios where fiber access bandwidth reaches 10G/100G/400G. It can realize the access of mobile base stations to the core network, transmit services between metropolitan area core nodes, provide access services for residential users, and access services for lower-level core networks of large-scale backbone networks.

The working principle of SCN-2662SC mainly includes the following: firstly, the optical signal coming from the user terminal is received, and then the optical performance is measured by the system control unit to determine the output power, dispersion and quality of the received signal, and then the received signal will be processed in its corresponding service board. The main function is to select and switch the processed signal. The selected and switching signals are input to the user line module, and the user line module realizes the forward and reverse transmission of optical signals with the user terminal.

After the signals are transmitted, the system control unit collects the received optical performance information of the two directions, stores and processes them, and conducts statistics of the forward and reverse optical performance of the user line port. After completing the processing of the received optical signal, SCN-2662SC will transmit the collected information to the upper-level network management platform, so that the upper-level network management platform can clearly know the link quality. Finally, the power supply of the system provides power supply for the system and its components, thus realizing the normal operation of the system.

In conclusion, SCN-2662SC is a comprehensive access service interface equipment, which has strong compatibility, good security, and rich features. It can provide 10G/50G/100G/400G services for fiber access networks, suitable for access of telecom core networks, service transmission in metropolitan area networks, last-mile access of FTTC/FTTH and other scenarios, which greatly improve network performance and service continuity.
