Juniper SNMP OIDs DDM for optical signal transceivers

I will give an example of receiving an optical signal via SNMP from optical transceivers connected to Juniper devices.

Huawei OLT DDM SNMP OID

Once on the highway to one of the Huawei MA5608, due to the heat and a bad cable, the optical level gradually deteriorated until the connection with the device was lost.
Therefore, I created triggers in Zabbix that will report that the signal is getting worse and this will prevent loss of connection.

DDM Port X optic module RX power exceeded the low warning/alarm threshold

One day, one of the DES-3200-28 B1 switches began to write the following in the logs:

BDCOM OLT DDM SNMP OID

Once it was necessary to monitor the level of the optical signal to the BDCOM OLT P3310C and P3608-2TE, after the trunk cables of different quality could stretch in the summer, and thus we lost contact with one of the OLT, although this situation could be predicted and prevented.
