Abstract

The invention discloses a space-borne optoelectronic hybrid switching framework suitable for relay broadband fusion communication, and relates to the field of satellite communication where relay and broadband satellite communication systems are integrated. It consists of five parts: interface adaptation unit, optical switching unit, packet switching unit, subband switching unit and management control unit. The interface adaptation unit realizes functions such as interface selection, rate adaptation, protocol adaptation, and integrated switching and interconnection; the optical switching unit realizes large-grained optical switching between trunk communication service ports, and the sub-band switching unit realizes medium-grained Broadband communication service sub-band switching, the packet switching unit realizes fine-grained broadband communication service data frame switching; the management control unit realizes the integrated management and control function. The invention has the advantages of supporting relay and broadband fusion communication services, supporting large-capacity multi-granularity integrated switching, and strong scalability, and is especially suitable for on-board photoelectric hybrid switching devices for relay broadband fusion communications.

Description

technical field [0001] The invention relates to a space-borne optoelectronic hybrid switching device suitable for relay broadband fusion communication, which belongs to the field of on-board switching of satellite communication system technology. Background technique [0002] In recent years, the advantages of satellite communication such as long transmission distance, fast and flexible deployment, seamless global coverage, high transmission bandwidth, good broadcasting capability and freedom from various geographical conditions have made satellite communication play an increasingly important role. Satellite communication systems can be subdivided into relay satellite communication systems and broadband satellite communication systems. At present, the two communication systems at home and abroad operate independently and develop independently. However, due to the limited resources such as orbital frequency and the development of laser communication technology, Considering fa...
