Abstract

The invention belongs to the technical field of communications and provides a technical solution for realizing high-speed data transmission in case of secure one-way data transmission. The technical solution includes a communication apparatus and method based on an SFP optical module. The apparatus comprises a programmable logic device which is provided with a parallel data interface and is capable of converting received data into data conforming to a predetermined format; a serial-parallel data conversion chip which is connected with the programmable logic device through a parallel bus and is capable of realizing mutual conversion between serial data and parallel data; and the SFP optical module which is connected with the serial-parallel data conversion chip through a serial data line and adopts a one-way communication mode without bidirectional verification during data transmission.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication device, system and method based on an SFP optical module, and more specifically, to a communication device and method based on an SFP optical module used in nuclear safety level-by-level communication. Background technique [0002] In the field of communication with high security requirements, such as the communication of nuclear power plants, for safety considerations, to ensure the information security of safety-critical equipment, the communication is often required to be one-way communication. It will be simpler and more reliable in the design of a secure communication network. [0003] Most of the unidirectional transmission solutions in the prior art have adopted signal transmission protocols with electrical connections, such as RS-422 (the full name is "Electrical Characteristics of Balanced Voltage Digital Interface Circuit", which defines th...
