Power supply device, optical module power supply system and power supply control method

Abstract

The invention discloses a power supply device, an optical module power supply system and a power supply control method, and belongs to the field of power supply control of optical modules in communication devices. The power supply device includes a power supply isolation control module and a processing module, The processing module is used for obtaining a voltage value of input voltage of an optical module group, and when it is determined that the voltage value satisfies a first range, a control instruction is sent to the power supply isolation control module, so that a power supply conversion module and the optical module group are disconnected, and the power supply conversion module stops supplying power to the optical module group. Through the functions of the processing module and power supply isolation control module, when an abnormality of the input voltage input to the optical module group occurs, the power supply conversion module and the optical module group can be disconnected, thereby preventing a fault that occurs in the optical module group from influencing other optical modules that work normally, reducing the technical risk of optical module group power supply, and improving the reliability of an optical module power supply system.

Description

technical field [0001] The invention relates to the field of power supply control of optical modules in communication equipment, in particular to a power supply device, an optical module power supply system and a power supply control method. Background technique [0002] In order to meet the continuous large-scale demand for data and information traffic growth in the society, modern data communication equipment is also developing towards the technical direction of large-capacity single machine, high-speed service port and high-density service port, and in the connection of these service ports, optical fiber It is widely used for its high bandwidth, low attenuation, soft and light weight, convenient wiring in the equipment room, and good EMI / EMC performance. At the same time, for high-speed service ports of 40G and above, currently only optical fibers can be used for interconnection between devices. In addition, the high density of service ports of data communication equipmen...

Problems solved by technology

At present, the power supply design of high-density SFP optical modules still only uses one power bus to directly supply high-density optical modules without any technical protection, which increases the technical risk of high-density optical module power supply methods and reduces the technical reliability of equipment. sex
