Optical fiber on-off intelligent sensing system

Abstract

The invention provides an optical fiber on-off intelligent sensing system, which is characterized in that a received optical signal is converted by an optical receiving end of an optical fiber verification monitoring part to obtain a digital signal; the received digital signals can be processed and calculated through an on-off state judgment unit, a dynamic loss value estimation unit, a communication performance evaluation unit and a fault risk evaluation unit of the data processing part, so that optical fiber link state information of the to-be-tested optical fiber is generated; the information can generate a corresponding optical fiber link state log through a report generation part for a supervisor to check and supervise, so that the optical fiber link can be dynamically monitored in real time by the light on-off intelligent sensing system; the optical fiber link can be better managed by checking the optical fiber link state log processed and calculated by the system, open circuit of the to-be-tested optical fiber is prevented, communication loss caused by excessive loss of the to-be-tested optical fiber is prevented by checking the dynamic loss value estimation information, and the daily maintenance work intensity of the optical fiber link is reduced.

Description

technical field [0001] The invention relates to an optical fiber on-off intelligent sensing system. Background technique [0002] The existing on-line monitoring of on-off and transmission performance of optical fiber links relies on real-time data exchange between ports connected to routers and switches to verify the on-off status and transmission performance of optical fiber links. This method needs to rely on switching equipment to implement cumbersome steps, and when the switching equipment is damaged, the fault source cannot be specifically determined, so there are disadvantages of unclear fault feedback and uncertain fault source. If the data link is disconnected due to natural disasters or accidents such as power outages, fires, earthquakes, and rats, it is impossible to immediately determine what caused the disconnection. In the field of national defense and security, in the event of accidental construction damage or eavesdropping on the intermediate link, the data ...

And because it is uncertain whether the other end of the optical cable link is plugged into the active device is working or the red light added by human testing, both visible light and invisible light have a certain degree of irreversible damage to human eyes, so there is a certain danger sex
