Optical Transponder Unit

The Optical Transponder Unit is located at the edge of the open WDM system, which converts the wavelengths of the accessed optical signals for transmitting them within a WDM system. After being installed, the optical transponder unit should be configured through this interface, thus loopback and cross-connect loopback can be set for fault localization.

In this user interface, you can provision the optical transponder unit, including following operations

Changing the primary state and secondary state.
Querying the wavelength, central frequency, transmit and receive time slot, and service type.
Setting laser status, speed band and payload.

Navigation Path

In the NE Explorer, click the NE and 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.

Port Name	For Example: IN1/OUT1	Displays the port name.
Laser Status	OPEN, CLOSE	Sets the status of a laser.
Automatic Laser Shutdown	ENABLE, DISABLE	Sets whether to shut down the laser automatically or not. If auto-shutdown is set, when the received signal is lost, the laser will shut down automatically, so that the laser service life is extended and body injury is avoided.
ALS Auxiliary Condition	FW_Defect, BW_Client_R_LOS, BW_WDM_Defect, FW_OPUk_CSF	When Automatic Laser Shutdown function is enabled, you can choose to set auxiliary conditions for ALS on Client port. NOTE: Several conditions can be chosen at the same time.
Hold-Off Time of Automatic Laser Shutdown	0s to 2s, step:100ms Default: 0s	Specifies the hold-off time for automatically disabling lasers. With ALS enabled, the hold-off time is a time period from the point when the system detects service interruption to the point when ALS automatically shuts down the related lasers.
Hold-off Time of Automatic Laser Turn-On	0s to 2s, step:100ms Default: 0s	Specifies the hold-off time for automatically enabling lasers. With ALS enabled, the hold-off time is a time period from the point when the system detects service recovery to the point when ALS automatically enables the related lasers.
FEC Working State	OFF, AFEC, STDFEC, AUTO	For NG WDM equipment, indicates whether the FEC is working and sets the FEC mode.
AFEC Grade	1, 2, 3	Set the AFEC grade. NOTE: The larger the grade is, the longer the error correction duration will be. Generally, you are not advised to set the grade ton 1.

Configure Wavelength No./Wavelength (nm)/Frequency (THz)	For example: 1/1529.16/196.050	Displays the working wavelength configured for the optical port. An configuration wavelength is a logical wavelength. During the optical cross-connection configuration, if temporarily no required actual wavelength is available, you can use the logical wavelength to configure the optical cross-connection.

Auto-Negotiation can automatically detect the optimized combination of working modes of the opposite port. This mode is easy to maintain and is recommended. Make sure that the working modes of this port and the opposite port are consistent. If the port modes are different, services are down.

Synchronous Clock Enabled	Disabled, Enabled Default: Disabled	Determines whether to enable lock synchronization. Set the parameter to Enabled if clock synchronization is required. When this parameter is set to Enabled, service clocks are synchronized with NE clocks. When the parameter is set to Disabled, service clocks will not be synchronized with NE clocks.
Reserved Overhead Transparently Transmitted	Y, N	Indicates whether the reserved overhead bytes is transparently transmitted with service cross-connections. It is applicable only to ODU2 service.
GCC Receive/Transmit Mode	ENABLE, DISABLE	WDM-side optical ports are usually used in pairs, and they can be configured as GCC channels working in either of the following modes: ENABLE: The two optical ports in a pair both act as GCC channels. They receive and transmit signaling independently. DISABLE: Only the selective receiving optical port acts as a GCC channel.
