A Realization Method of Hybrid Flexible Transponder

Abstract

The invention discloses a method for realizing a hybrid flexible transponder, and mainly relates to all-optical frequency conversion and all-optical switching technologies in the communication field, as well as technologies such as non-uniform channelization and circuit switching. The implementation structure of the present invention is mainly composed of two parts: microwave photon forwarding and microwave digital flexible forwarding. Microwave photon forwarding makes full use of the advantages of photonics broadband, high speed, and low power consumption, and can realize transparent forwarding with large granularity and variable bandwidth; microwave digital flexible Forwarding as an aid can realize small and medium granularity variable bandwidth transparent forwarding and processing forwarding. The two parts can realize flexible forwarding of multi-beam and different granularity bandwidth signals through the joint control of on-board control equipment. At the same time, the hybrid flexible transponder also provides multiple digital interfaces externally, which can be connected to the on-board packet switching processing load. The invention has the advantages of low implementation complexity, support for reconfigurable design and multi-mode forwarding, and the two parts of microwave photon forwarding and microwave digital flexible forwarding can also be used independently.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for realizing a hybrid flexible transponder, which is especially suitable for supporting the application requirements of a multi-beam, multi-functional and reconfigurable general-purpose satellite transponder. Background technique [0002] At present, the technical approaches used to realize information forwarding and exchange between multi-beam satellite load beams mainly include packet switching based on on-board full processing, microwave matrix switching based on on-board transparent forwarding, and on-board partial processing based on the combination of the above two methods. Microwave digital forwarding switching. [0003] The microwave matrix switching technology based on transparent forwarding on the satellite realizes the transparent forwarding of the satellite. The satellite does not process the user signal, and the signal format and content have nothing to do with...

AI Technical Summary

Problems solved by technology

The cost is to increase the complexity of the satellite, and it has a dependency on the physical layer, and it will also greatly increase the quality of the satellite and the power consumption of the load.

At the same time, the transmission format and service type of the system are fixed, which cannot adapt to the update of technical standards or communication protocols, and the flexibility is poor, which will cause difficulties for the application of new technologies and the expansion of new services

Moreover, in the case of many beams, the packet switching method may be too complicated to realize

[0005] In short, the main problems faced by satellite transponders at present are heavy weight, large volume, poor system flexibility, high power consumption of the system, and the capacity of transponders is difficult to adapt to the growth of demand and sudden business, and the adaptability and scalability are not enough.
