Abstract

The invention relates to communication equipment, and provides a front-end circuit of an SFP slot and a router, and the front-end circuit comprises a power supply circuit which is coupled with the SFP slot and is used for providing direct current; a detection circuit, connected with the SFP slot, and used for detecting the type of a module inserted into the SFP slot, and controlling the power supply circuit to change the voltage of the output direct current to the SFP slot according to the determined type of the module, so that the module is electrified to establish communication with the SFP slot; the module comprises an optical module, an electric module and a USB module with an SFP structure. When any module is connected into the SFP slot, an internal insertion detection system identifies the type of the inserted module and performs self-adaptive power supply, and after normal power supply, the structures of the SFP slot and the SFP module are converted into corresponding interfaces through system configuration, so that the functions of the interfaces are realized.

Description

technical field [0001] The application belongs to the technical field of communication equipment, in particular to a front-end circuit and a router of an SFP slot. Background technique [0002] At present, there are two disadvantages in the existing routers. One is that the interface of Universal Serial Bus (USB) and the interface of Small Form-factor Pluggables (SFP) are not compatible with each other in structure. Pure USB interface routers and pure SFP Neither interface router does a good job of covering the needs of all users. However, a router equipped with two types of interfaces at the same time not only has high manufacturing costs, but also has two types of interfaces that take up a lot of space and has high requirements for housing design and heat dissipation solutions; moreover, the USB interface circuit and the SFP interface circuit cannot be reused in circuit design. The design of the conversion circuit and the power supply circuit of the two interfaces is quit...
