a. The main and backup power supply configuration ensures the uninterrupted operation of the system;

　　b. Support AC220V and DC-48V two power supply modes, making the system suitable for a variety of working environments;

　　c. Module cards that support multiple models and rates work at the same time, which greatly improves the applicability of the system;

　　d. Up to 14 independent optical fiber transceivers can be inserted into the rack at the same time, and each optical transceiver can be of different types;

　　e. Each independent optical fiber transceiver can be plugged and unplugged on the rack independently of each other, and can also work in cooperation with each other to provide network diagnosis for itself 6.

　　h. Power protection: overvoltage protection, overcurrent protection, short circuit protection;

　　g. Structural design, exquisite and beautiful, good ventilation and thermal conductivity design, to ensure the normal and stable operation of the system;

　　h. Support dual-fiber multi-mode, dual-fiber single-mode and single-fiber single-mode multiple fiber port options, expanding the needs of users.

　　The 14-slot dual-power optical fiber transceiver rack is an economical and highly integrated optical fiber transceiver center equipment used in the transceiver rack of the equipment room. Up to 14 different types of fiber optic transceiver module cards can be inserted, which are powered by the main and backup power supplies and can be automatically switched. This not only reduces the number of connecting lines, simplifies the structure, but also facilitates management and maintenance. The rack has a reliable protection device function (to protect the optical fiber transceiver module from being damaged by the external AC220V surge and high voltage); it provides a reliable voltage stabilizer source and has the function of automatic load balancing, which ensures that no matter how many optical fiber transceiver modules are connected, The single-slot voltage of the provided module is a standard voltage, which ensures the reliability and stability of the performance of the optical fiber transceiver module, and provides conditions for life consistency. The power supply adopts dual backup design, which can provide high reliability, high capacity, high integration, high performance and economical and practical optical fiber network center solution for optical fiber Ethernet system, with stable operation, large power supply capacity, convenient operation and easy operation. Maintenance and other notable features.
