### Check Info *huawei_entity_optical_temp*

* *service*: this check creates the service *Temperature* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: upper and lower limits
* *perfdata*: 
    * Temperature in °C


### Sample output

---
### Check Info *huawei_entity_optical_current*

* *service*: this check creates the service *Current* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: upper and lower limits
* *perfdata*:
    * Electrical current in Ampere

### Sample output

### Check Info *huawei_entity_optical_dom*

* *service*: this check creates the service *DOM* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: lower and upper levels for RX/TX signal power and levels for deviation.
* *perfdata*:
    * RX and TX signal power in dBm
    * RX and TX signal power deviation in dBm

Deviation extension is based on [CheckMK PR #211](https://github.com/tribe29/checkmk/pull/211) *Add deviation power to cisco_temperature.dom* by [*agabellini*](https://github.com/agabellini)

### Check Info *huawei_entity_optical_voltage*

* *service*:  this check creates the service *Voltage* for each SFP with the interface name as the item
* *state*: **critical**/**warning** if outside the limits
* *wato*: upper and lower limits
* *perfdata*:
    * Voltage in Volt
