Abstract

In the space environment where laser links and microwave links coexist

the development of satellite Internet optical/electric hybrid switching will help promoting the construction of air-space-ground integration.According to the characteristics and transmission requirements of satellite Internet services

the current status of electrical domain switching technology and optical domain switching technology were investigated and analyzed

and the applicability of existing switching technologies in the construction of satellite Internet was summarized.At the same time

according to the analysis results

the end-to-end network on the satellite was constructed

and based on this

the design of the optical/electric hybrid switching architecture on the satellite was completed.It mainly included the interface

electrical domain adaptation module

optical domain adaptation module

optical/electric convergence module

optical switching module

packet switching module and management control module.
