Mixed format signal optical fiber transmission device

Abstract

The invention discloses a mixed format signal optical fiber transmission device. The mixed format signal optical fiber transmission device comprises a sending end, a fiber channel and a receiving end, wherein the sending end converts input camera link format video image signals and multi-channel universal serial signals into optical signals, the optical signals are sent to the receiving end through the fiber channel, and the receiving end receives the optical signals and restores the optical signals to original video image signals and multi-channel universal serial data signals. The mixed format signal optical fiber transmission device is suitable for optical fiber transmission of the camera link video image signals and the multi-channel universal serial signals in all configuration modes, the transmission of mixed format signals in a single-fiber channel at different rates can be achieved through multiplexing of a transmission bus, and consumption of extra fiber channels and devices is reduced. According to the mixed format signal optical fiber transmission device, electrical signal conversion processing and transmission control are achieved through a field programmable gate array (FPGA) device, the requirement for actual functions is met, meanwhile, the usage of application-specific integrated circuits is reduced, the advantage of high integration and universalization degrees can be achieved, and supports can be provided for further function extension and performance upgrading.

Description

technical field [0001] The invention relates to the technical field of signal processing and transmission, in particular to a mixed-format signal optical fiber transmission device. Background technique [0002] With the continuous improvement of frame frequency and resolution, the bandwidth of current video image acquisition equipment can reach the level of gigabits per second (Gbps), and it is difficult for cables to meet the reliable transmission of high-speed video image signals over a distance of ten meters. Optical fiber transmission has the characteristics of high bandwidth, strong anti-electromagnetic interference performance, and long transmission distance. Now it has gradually replaced cables in high-speed and long-distance data transmission applications. [0003] At present, the optical fiber transmission equipment at home and abroad is aimed at the single-format signal transmission, which cannot satisfy the real-time transmission of high-speed image signals and ot...

Problems solved by technology

[0003] At present, the optical fiber transmission equipment at home and abroad is aimed at single-format signal transmission, which cannot satisfy the real-time transmission of high-speed image signals and other format signals at the same time. Disadvantages of being large, expensive and difficult to maintain

At the same time, this type of high-speed optical fiber transmission equipment is generally designed and implemented by application-specific integrated circuits, which are limited in terms of function expansion, performance upgrades, and adaptability to the working environment.
