Embodiment Construction
[0017] The invention proposes a method for judging the optical power of an ONU through an indicator light.
[0018] refer to figure 1 , figure 1 It is a work flow diagram of an embodiment of the present invention.
[0019] Such as figure 1 As shown, in the embodiment of the present invention, the method for judging the optical power of the ONU through the indicator light includes the following steps:
[0020] S100, writing various parameters required by the method in the software of the ONU. Various parameters include: detection period = 10 seconds, ONU saturated optical power value = -8db, ONU engineering value = -24db, ONU sensitivity value = -32db, slow flash interval value = 1 second, fast flash interval value 500 milliseconds , Step value = 0.5db, and the reference value N = 2 for the number of flashes of the indicator light.
[0021] S200, start the software when the ONU is working, and read various parameters in step 100.
[0022] S300, the software reads the curr...

The invention discloses a method for judging the optical power of an ONU through an indicator light, which comprises the following steps: writing various parameters required by the method in the software of the ONU; starting the software when the ONU is working, and reading various parameters; Read the current time and judge whether the current time has reached the detection cycle; the software reads the current optical power value received by the ONU; the software judges whether the current optical power value is greater than the ONU saturation optical power value; the software judges whether the current optical power value is less than the ONU sensitivity value; the software judges whether the current optical power value is less than the ONU engineering value. The beneficial effect of the present invention is that the optimized processing method complies with the China Telecom standard, and the ONU can more accurately locate the state of the current optical power through the indicator light when the optical power is abnormal. During the construction process, it is not necessary to carry an optical power meter. It is convenient for maintenance personnel to quickly understand the optical power status of the ONU, so as to troubleshoot for customers in time.
Description
technical field [0001] The invention relates to the technical field of methods for judging ONU optical power, in particular to a method for judging ONU optical power through indicator lights. Background technique [0002] In the existing communication network, the indicator light requirements of Table 24-1 ONU in the PON system "Technical Requirements for EPON Equipment of China Telecom" stipulates that the status of the LOS light is: LOS off means that the ONU receiving optical power is normal, and LOS blinking means that the ONU receiving optical power is low on the sensitivity of the optical receiver. The method for judging the current optical power state of such an indicator light is not accurate enough, it can only indicate whether the optical power is low, and it is inconvenient for the user to know the current optical power value of the ONU more accurately. Contents of the invention [0003] Aiming at the problems existing in the prior art, the main purpose of the ...
