Alarm threshold query for optical modules on WDM equipment

1

Run the :cfg-get-almth:bid,port,path,th-type command to query the alarm threshold. The th-typeb field indicates the alarm threshold type.

Processing of transient TF alarms on WDM equipment
The processing rules are as follows: 1. If the TF alarm is reported by TC1 or TC2, directly replace the board no matter whether the alarm is reported transiently or persistently. 2. For 71SC1/71SC2: a. If the TF alarm is transiently reported, upgrade the board software to 1.12 or a later version. b. If the TF alarm persists for 5s or longer, or the alarm is still transiently reported after the board software upgrade, replace the board. Most transient TF alarms can be avoided by software upgrades. 3. E1SC1/SC2: a. If the TF alarm is transiently reported, upgrade the board software to 1.27 or a later version. For versions earlier than 1.27, the workarounds are not complete therefore the board software upgrade cannot avoid this alarm. b. If the TF alarm persists for 5s or longer, or the alarm is still transiently reported after the board software upgrade, replace the board. Most transient TF alarms can be avoided by software upgrades.

Restrictions on the alarm reversion function of WDM equipment
1. The NE software of WDM equipment in each version supports alarm reversion. The alarm reversion has three modes: disabled (no reversion), manual (permanent reversion), and automatic (one-off reversion). 2. Currently, only the R_LOS and MUT_LOS alarms of WDM equipment support reversion, and no other LOS conditions are available. 3. Alarm reversion takes effect only on the NE software. The actual alarm status still exists on boards. Alarms are saved in the blackboxes of boards and can be queried using a PTP command. By running the :alm-set-bsrep:bid,enable command, you can also find that alarms are reported from boards to the NE software.

Method used to calculate the optical cable attenuation between WDM equipment
The attenuation of an optical cable between WDM equipment can be calculated using the following formula: Optical cable attenuation = Difference between the transmit optical power of one OA board and the receive optical power of the peer OA board �?(Insertion loss of the two FIU boards in the middle + Attenuation of the optical attenuator)

Method to query the wavelength information of a line board on WDM/OTN equipment
In the NE Explorer, select the target board and choose Configuration > WDM Interface from the navigation tree. On the Advanced Attribute tab, wavelength information is displayed.

Dustproof requirements for WDM equipment
The operating environment requirements of WDM equipment must comply with IEC 60529 (Degrees of protection provided by enclosures).
