The CF-2U16 is a Fiber media converter independently developed by CF FIBERLINK. supports up to 16 card-type business units, supports a variety of hybrid access optical transceivers of different specifications, and provides a unified power supply. Reducing the connection line is simplified, the structure is simplified, and it is easy to manage and maintain. The rack supports hot-swap and can choose a single power supply or dual power supply mode. When using dual power supplies, the two power supplies will supply power at the same time, which reduces the load of each power supply and prolongs the service life of the power supply. When one power supply fails, the other power supply can supply power independently so that the work of the converter is not interrupted. When repairing and replacing the power supply, it is not necessary to pull out the fiber media converter or remove the rack from the cabinet. It is only necessary to pull out the faulty power supply from the back of the rack for repair or replacement, which makes maintenance extremely convenient and fast. Therefore, it can provide high reliability, high capacity, high integration, high performance, and economical and practical optical fiber network center solutions for the optical fiber Ethernet system. It has the remarkable characteristics of stable operation, large power supply capacity, convenient operation, and easy maintenance. It is suitable for optical fiber access application scenarios such as security monitoring, wireless coverage, intelligent transportation, and safe cities to build cost-effective and stable communication networks.
