Variable Optical Attenuation Unit

The variable optical attenuator unit can detect and adjust the channel optical power in real time, which is used to maintain the power value within the system required range. After being installed, the variable optical attenuator unit needs to be configured through this interface.

In this user interface, you can change the primary and secondary state and set the attenuation rate of the variable optical attenuation unit.

Navigation Path

In the NE Explorer, select a card and select Configuration > WDM Interface from the Function Tree.

Buttons

Button		Description
By Card/Channel		Lists port parameters of all selected NEs and cards.
By Function		Lists a selected port parameter of all selected NEs and cards.
Power Saving	SB	Start power saving function of the channel. NOTE: The state of power saving can not be set as SB when the channel is in the Remove state.
Power Saving	SB-DEA	Cancel power saving function of the channel.
Maintenance	Remove	Changes the service state of the specified port to Out of Service - Maintenance (OOS-MA, MT). After the remove action, there is no alarm generated for the corresponding facility and existing alarms must be cleared. Any circumstances are reported as not required (NR) and performance message (PM) continues to be collected and is marked invalid. This is done before performing loopback and NULL mapping status.
Maintenance	Restore	Instructs an NE to restore service of the port on the card. The card will change the port state from maintenance to the original state. All existing alarms must be reported.
State	IS	Sets the state of the ports to be in service.
	OOS	Sets the state of the ports to be out of service.
	AINS	Sets the state of the ports to be automatic in service.

Parameters

Field	Value	Description
Optical Interface	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name)-monitoring level Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)-monitoring level	Displays Optical interface Name.
Primary, Secondary State	OOS-AUMA,UEQ&UAS; OOS-MA,UAS; OOS-AU,UEQ; OOS-AUMA,UEQ; OOS-AU,AINS&UEQ; OOS-AU,MEA; OOS-AUMA,MEA; OOS-AU,AINS&MEA; OOS-AU,FLT; OOS-AUMA,FLT; OOS-AU,AINS&FLT; OOS-MA; IS-NR; IS-NR,SWDL; OOS-MA,SWDL	Displays the state of the slot. OOS-AUMA,UEQ&UAS: The card is not created and in position. OOS-MA,UAS: The card is not created but is in position. OOS-AU,UEQ: The card is in the IS state but not in position. OOS-AUMA,UEQ: The card is in OOS state but not in position. OOS-AU,AINS&UEQ: The card is in AINS state but not in position. OOS-AU,MEA: The card is in the IS state and in position. But the logic type of the card and its physical type mismatch. OOS-AUMA,MEA: The card is in the OOS state and in position. But the logic type of the card and its physical type mismatch. OOS-AU,AINS&MEA: The card is in the AINS state and in position. But the logic type of the card and its physical type mismatch. OOS-AU,FLT: The card is in the IS state and in position. But the card fails. OOS-AUMA,FLT: The card is in the OOS state and in position. But the card fails. OOS-AU,AINS&FLT: The card is in the AINS state and in position. But the card fails. OOS-MA: The card is in the IS state and in position. But it is changed to the OOS state manually. IS-NR: The card is in the IS state and in position. No card failure. IS-NR,SWDL: The card is in the IS state and in position. Software is being loaded. OOS-MA,SWDL: The card is in the IS state and in position. But it is changed to the OOS state manually. Software is being loaded.
Signal Validation Timer	00-03 to 48-00	Sets the signal validation time.
Port Name	For example: IN1/OUT1	Displays the port name.
Attenuation (dB)	An integer number	Sets the attenuation ratio of the optical port. Different cards have different attenuation rate.
Port Remarks	Character string	Displays the port remarks of the card.
Provision Working Band Type	C-EVEN, C-ODD, C-ALL	Displays the parity of the current working band of the port.
Actual Work Band	CBAND, CWDMBAND	Displays the actual working band.
Min Attenuation (dB)	0 to 21.5	Queries and displays the minimum attenuation.
Max Attenuation (dB)	0 to 21.5	Queries and displays the maximum attenuation.
Loss Laser Threshold (dB)	For Example: -35.0	Displays the loss laser threshold.
VOA Offset (dB)	-3.0 to 3.0	Sets the VOA offset value.
