Abstract

The invention discloses a high-performance optical fiber board card power supplying unit. The high-performance optical fiber board card power supplying unit comprises a port A and a port B. A first one-level power management chip is connected to the port A, a plurality of two-level power management chips are connected to the first one-level power management chip, and a plurality of second one-level management chips are connected to the port B. The high-performance optical fiber board card power supplying unit has the advantages that due to the fact that power is supplied to all modules independently on an optical fiber board card, and all modules are physically separated, requirements for power of each module are met, all modules are not affected mutually, and superior performance is achieved.

Description

technical field [0001] The invention relates to a power supply device, in particular to a high-performance optical fiber board power supply device. Background technique [0002] Because optical fiber communication has the advantages of large capacity, high quality of transmitted information, long transmission distance, stable performance, anti-electromagnetic, and strong corrosion resistance. Fiber Channel is a high-performance serial transmission protocol with high bandwidth and high real-time characteristics, and has become the preferred solution for the network interconnection of a new generation of advanced integrated electronic systems. As the interface between the electronic system and the network, the optical fiber data card is a key part of the electronic network, and its research has become an important and urgent task. The power supply on the fiber optic card generally adopts the first-level power supply method, that is, the 12V power supply directly supplies powe...
