Problems solved by technology

[0003] In the existing technology, the network firewall technology has been unable to fully cope with the increasingly complex security threats. The efficiency of exchanging internal and external network data with the help of mobile encrypted storage devices is low, and data leakage during transmission cannot be guaranteed.
In addition, factors such as data loss and data leakage also seriously restrict the reliability and security of data transmission.

Abstract

This application discloses a data transmission system and method based on optical communication. The data transmission system includes: an intranet processing unit, which is used to receive the original business data sent by the intranet customer service system, and encrypt and convert the original business data into data stream; the transmission unit is used to receive the data stream, and transmit the data stream after photoelectric conversion; the external network processing unit is used to receive the photoelectrically converted data stream transmitted by the transmission unit, and restore the processed data stream to Raw business data. Through the above method, the present application can increase the throughput of data transmission, and the use of optical information transmission has strong confidentiality, which can ensure that data information will not be intercepted.

Description

technical field [0001] The present application relates to the field of network technology and information security, and in particular, to a data transmission system and method based on optical communication. Background technique [0002] Network information security threatens the rapid popularization and development of the Internet, and has been paid attention to by relevant enterprises and government departments. Efficient and secure data transmission between network domains with different security levels has become an urgent need for important secret-related departments such as the government, military industry, and finance. Due to the high level of internal network security built by sensitive departments, data often needs to be transmitted externally across network domains to achieve information sharing between different industries and departments. [0003] In the prior art, the network firewall technology has been unable to fully cope with the increasingly complex secur...
