Abstract

The present application discloses a signal error warning method, and relates to the field of communication technologies. The method includes that: an optical module receives an optical signal sent byan optical fiber through a line side interface, converts the optical signal into a digital signal, and sends the digital signal to an FEC module; the FEC module counts the number of errors in the digital signal, and calculates the error rate of the digital signal. When the error rate is lower than a preset threshold, the digital signal is corrected, and the error-corrected digital signal is sent to a PCS module, and when the error rate is higher than the preset threshold, the error alarming is performed. The present application solves the problem that if the digital signal has an error, the processing device may have a processing error; when the error rate is lower than the preset threshold, the error-corrected digital signal is sent to the processing device, and when the error rate is higher than the preset threshold, the error alarm is sent to remind the technician to perform the fiber maintenance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a signal error code warning method and device. Background technique [0002] The generation of bit error is because in the process of signal transmission, the decay of the signal changes the quality of the signal, causing the signal to be destroyed, thus generating bit error. Noise, pulses from alternating current or lightning, transmission link failures, and other factors can cause bit errors. [0003] A network interface is a component used to convert optical signals into digital signals. Usually, when the optical module of the network interface receives the optical signal transmitted by the optical fiber through the system side interface, it will convert the optical signal into a digital signal, and transmit the digital signal to the PCS module, and the PCS module will encode and decode the digital signal , and transmit the coded digital signal to the MAC module, and ...
