[0024] Such as figure 2 , the industrial Ethernet switch provided by the present invention includes an optical power meter and a processor.

[0025] The optical power meter is used to detect the optical power of the optical signal input by the optical port of the industrial Ethernet switch; the processor is used to calculate the difference between the optical power and the light receiving sensitivity, if the difference between the two is less than the margin setting value Then, the alarm information of insufficient received power headroom and the corresponding optical fiber number are sent to the management server through the network.

[0026] Optical receiving sensitivity is also called the minimum received optical power. For optical fibers with a bandwidth of 100MHz, its typical sensitivity value is usually -35dBm, and for optical fibers with a bandwidth of 1000MHz, its typical sensitivity value is usually -25dBm.

[0030] The power loss of the optical fiber is also an important indicator for detection. In another embodiment, when the switch sends a signal, it will also transmit its own transmitted optical power and output data to the opposite switch through the optical fiber. The processor in the opposite switch also It is used to extract the transmitted optical power of the sending end from the optical signal input by the optical port of the industrial Ethernet switch, calculate the difference between the optical power output by the optical power meter and the transmitted optical power, and divide the difference by the fiber length to obtain the actual fiber loss per unit length , if the value is greater than the loss setting value, the alarm information of excessive fiber optical power loss and the corresponding fiber number will be sent to the management server through the network.

Abstract

The present invention discloses an industrial Ethernet switch with optical power detection, relates to the industrial Ethernet switch optical power detection technology, and provides an industrial Ethernet switch capable of automatically detecting and receiving optical power. The industrial Ethernet switch comprises an optical power meter and a processor. The optical power meter is configured to detect the optical power of the optical signals inputted by the optical port of the industrial Ethernet switch; and the processor is configured to calculate the difference value of the optical power and the optical receiving sensitivity, and if the difference value therebetween is smaller than a margin setting value, the alarm information about insufficient receiving power margin and corresponding optical fiber numbers are sent to a management server through a network.

Description

technical field [0001] The invention relates to an optical power detection technology of an industrial Ethernet switch, in particular to an industrial Ethernet switch equipped with optical power detection. Background technique [0002] In the prior art, when the communication of a certain optical path (including multiple industrial Ethernet switches and the optical fibers between each industrial Ethernet switch) is interrupted, it is necessary for the staff to go to the site to detect each section of optical fiber in the optical path one by one, and determine whether it is found. Which segment of the optical fiber is interrupted in communication, for maintenance or replacement. At present, a large number of industrial Ethernet switches and optical fibers are deployed in the wild and located in remote locations. The workload of the staff to detect each segment of optical fiber is very heavy and the working environment is complex, which leads to low detection and troubleshooti...
