Abstract

Abstract:

To meet the demands of high-speed communication under strong electromagnetic interference, an all-light network (ALN) based on a multi-band optical communication system is proposed. It is designed for cross-scenario interconnection and networking, covering air, space, land, and sea. The ALN integrates four types of optical links: underwater blue light communication, white light illumination communication, solar-blind deep ultraviolet communication, and long-distance laser communication systems. These links are interconnected via Ethernet switches with the Transmission Control Protocol (TCP). Any ALN node supports both wired and wireless device access. The data transmission performance between network nodes was tested, with a maximum transmission delay of 73.3 ms, a maximum packet loss rate of 6.1%, and a maximum jitter of 15 ms. This comprehensive all-light network with all-scenario coverage lays the foundation for the future development of network technologies and the digital economy.

Key words: all-light network, multi-band optical communication system, Ethernet switches
