Description

Technical Field

[0001] The present invention relates to the field of link performance testing, and specifically to a microwave photon testing device and a multi-link performance testing system. Background Art

[0002] Both optical fiber communication and optical fiber sensing systems require optical fibers and optical fiber devices for optical signal transmission. In particular, large and complex optical fiber systems are composed of various optical fiber devices such as optical switches, beam splitters, and couplers. Existing insertion loss and return loss testers are only applicable to fixed point-to-point insertion loss and return loss testing. When an optical path switch occurs in an optical switch, existing instruments cannot determine whether the optical path has switched; and when the internal variable optical fiber links of dozens or hundreds of inputs and outputs are abnormal, there are tens of thousands of connection methods for inputs and outputs. Microwave frequency signals play a crucial role in multiple fields such as communication, radar, electronic warfare, and measurement. With the development of the new generation of electronic information systems towards broadband, array, generalization, and networking and the transformation of its technical system, microwave frequency signals inevitably need to be transmitted over long distances in a large range. Optical fiber transmission is an efficient and low-loss transmission method that can resist electromagnetic interference and can transmit a large amount of information. However, the optical fiber transmission delay will change with factors such as the external environmental temperature and vibration, which will seriously affect the performance improvement of electronic information systems.

[0003] Multi-link transmission MLO not only realizes an increase in throughput through link aggregation but also brings lower latency with higher reliability. However, the traditional multi-link MLO performance testing method is relatively complex and the testing cost is high. Therefore, the present application proposes a microwave photon testing device and a multi-link performance testing system. Summary of the Invention
