Embodiment Construction

[0021] Such as Figure 1~3 Shown, video optical fiber transceiver of the present invention comprises:

[0022] Camera-side interface module: the camera-side interface module includes a camera adaptive module, a cache module, and an external interface module. The function is to meet the camera sending timing, collect camera data, buffer and process the data, and send it to the high-speed serial transceiver according to the FPGA clock. By changing the FPGA parameters to adjust the blanking time of the collected data, it has the adaptability to different acquisition cards. It can flexibly control the field control signal and change the resolution of the collected images.

[0023] Acquisition card interface module: The acquisition card interface module includes a reset module, an external interface module, and a clock module. The function is to generate the acquisition timing that meets the acquisition card, and provide the reset and acquisition clock of the high-speed serial t...

Abstract

The invention relates to a video fiber optic transceiver. The video fiber optic transceiver comprises a camera-end interface module composed of a camera adaptive module, a buffer module and an external interface module, an acquisition card interface module composed of a reset module, an external interface module and a clock module, and two high-speed serial transceivers. One high-speed serial transceiver is connected with the camera-end interface module. The other high-speed serial transceiver is connected with the acquisition card interface module. The other ends of the two high-speed serial transceivers are connected with a fiber optic module. The high-speed serial transceivers can convert parallel data into serial data and then transmit the serial data to a high-speed serial receiving terminal. In this way, the serial data are reset to be the original parallel data and then are sent out. The video fiber optic transceiver can be used as either a receiving terminal or a transmitting terminal. Therefore, during the practical application process, whether the video fiber optic transceiver must be connected with a camera or an image acquisition card is not a problem any more.

Description

technical field [0001] The invention relates to the technical field of optical fiber transceivers, in particular to a video optical fiber transceiver. Background technique [0002] With the rapid development of computer technology and communication technology, digital video plays an increasingly important role in the information society, and is widely used in many fields such as traffic management, industrial monitoring, radio and television, banks, shopping malls, etc. The combination of FPGA high-speed serial transmission and optical fiber transmission technology has the advantages of long transmission distance, large information capacity, strong anti-interference ability, and good confidentiality. [0003] The fiber optic transceivers in the prior art are divided into a receiving end and a transmitting end, which are inconvenient in practical application due to their similar shapes. Contents of the invention [0004] The invention aims to solve the technical problems i...
