Problems solved by technology

If the test results of each channel are connected to the back-end data processing equipment through a cable, the system connection will be complicated and a large amount of hardware resources will be consumed. On the other hand, once multiple one-to-one data links are formed, it will be difficult to expand The number of channels is not conducive to equipment compatibility and general use

Abstract

The invention discloses a multi-interface high-speed optical fiber transmission device and method. The multi-interface high-speed optical fiber transmission device comprises a digital signal processing module, an optical module, an optical fiber cable and a data processing server, the digital signal processing module is used for completing digital beam forming and parameter measurement of the received baseband signal; a result of the signal processing module is accessed to a data processing server through an optical module and an optical fiber cable for further signal identification; the optical module completes electro-optical conversion between the electric signal sent by the digital signal processing module and the optical signal transmitted in the optical fiber cable, and photoelectric conversion between the optical signal transmitted in the optical fiber cable and the electric signal received by the data processing server; according to the invention, on the premise of not changing the architecture of the back-end data processing server, the receiving front-end module is expanded; and meanwhile, on the premise of not losing data, multiple channel outputs are combined into one channel for transmission, so that the system redundancy is reduced, the hardware resource utilization rate is improved, and the hardware cost and the system unit design complexity are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a multi-interface high-speed optical fiber transmission device and method. Background technique [0002] Modern electronic reconnaissance systems can monitor enemy military facilities, land, sea and air radio equipment around the clock and provide us with intelligence information. The reconnaissance equipment has many application scenarios and wide frequency band coverage. The types of its platforms are increasingly diverse, and the number of access data channels is increasing. In the reconnaissance system, the signal processing front-end needs to detect multi-beam data of various systems, modes and frequency bands, so the output detection results are composed of multi-channel data. If each test result is connected to the back-end data processing equipment through a cable, the system connection will be complicated, resulting in a lot of hardware resource consum...
