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...
