Optical power management : ALS function

Note that ALS function need to be activated on each port, in this way the laser will not harm anybody!

When a client-side or WDM-side fault occurs during the transmission of non-OTN services, the automatic laser shutdown (ALS) function, if being enabled, shuts down the laser(s) on the associated transmit ports. It turns on the laser(s) on the transmit port(s) again when the fault has been eliminated.
 
The automatic laser shutdown (ALS) function needs to be configured at each required port.
 
ALS application for Huawei OSN 8800

How many versions does Huawei OSN 8800 Optical Amplifier Board OAU1 have?

AU1 is a WDM optical amplifier board, to amplify C band optical signals at different Gain Ranges; OAU1 has three versions TN11, TN12 and TN13.

TN11OAU and TN12OAU will occupy two slots on Huawei OSN 6800 or Huawei OSN 8800; TN13OAU only occupies one slot.

Also they have function difference. TN11OAU1 board does not support adjustment of input optical power, whereas the TN12OAU1 and TN13OAU1 board supports
