Description of the invention ("() Monitoring the optical power output status of the optical transmitters 22 of various manufacturers'. The method is to add an optical branching module 26 between the optical transmitter 22 and the optical fiber, and capture a small amount of optical power 50 to the optical power signal processing unit 56 for monitoring values. 5 Simultaneously through micro processing The processing flow of the transmitter 64 starts 70 to receive the various operation status values 72 of all measuring light transceivers, and judges whether the various operation status values exceed the normal value No 74. If yes, start dialing and send the alarm signal back to the monitoring The host 76, otherwise the microprocessor 64 will continue to process and judge the various operating state values 72 of all the measuring light transceivers and transmitters. 10 Please refer to Figure 25. In terms of monitoring the host 20, it is responsible for the two main Task 'One is to receive the alarm signal that the optical transceiver / transmitter monitoring repeater may return at any time' and the other is that the management staff can monitor the host 2 at any time through the public telephone network 14 Connect with any optical transceiver / transmitter monitoring transponder to check the latest status of the monitored optical transceiver / transmitter. The processing method is that the monitoring host 20 starts 80 to start dialing a certain optical transceiver / transmitter The monitoring repeater is planned to judge whether the dial-up is successful 84. If the dial-up times are more than three times and the 86 cannot be connected, the monitoring host displays the unknown status of the optical transceiver / transmitter 88 and informs the administrator to troubleshoot the problem. If the number of times is less than three times, the dial-up of a certain optical transceiver / transmitter monitoring transponder 82 will continue to be activated; if the dial-up is successful, the operation status value of the optical transceiver / transmitter will be measured 90, and the various operation status values will be determined to exceed If the normal value is 92 ', the alarm signal will be issued and related processing will be performed. If it is still within the normal value range, the record will be updated to 96; and then other monitoring transponders will be dialed to perform other optical transceivers.
