Description

System and method for monitoring port connection status

Technical field

Background technique

With the development of mobile networks, in the operator's computer room, fiber jumpers are becoming more dense and the number of devices is increasing. Because the connection status of the ports of the optical fiber tandem device is not easy to monitor and manage, the ports are easy to be mistakenly inserted into or unplugged from the optical fiber. At the same time, with the development of communication networks, the number of computer rooms and equipment has increased, and unified monitoring and management of existing equipment resources is required. This requires remote monitoring and management of the port connection status in real time.

The existing connection state monitoring technologies based on fiber tandem device ports are roughly divided into two types. One is to apply an optical fiber intelligent connector, install an electronic tag chip in the optical fiber connector, and install a detection chip in the corresponding port flange. This technology can monitor the ports in real time, determine whether the fiber is in place, and can intelligently manage the ports and fiber ports. However, because the chip needs to be set on both the optical fiber connector and the port flange, this technology greatly increases the system cost and complexity, and also leads to an increase in later maintenance costs. Another type of fiber tandem device port connection status monitoring technology is to add optical components to the port for detection. For example, a filter and reflector are added to the port, and the time difference between the detection light passing through the transmitter is used to determine the port type and the optical fiber. Bit situation. This technology has no special requirements for fiber optic connectors, and the cost is relatively low, but it needs to allocate a specific wavelength for detection, that is, it needs to add an additional light source, which is not suitable for remote real-time monitoring. In addition, adding optics will also increase the insertion loss of the port.

Therefore, how to realize the real-time monitoring of the port connection status is still an urgent problem in the field of optical communication technology.

During use, the user can change the authorization of the port at any time. The microcontroller will compare the port status information with the authorization information to determine whether the alarm needs to be refreshed.
