Optical Transponder Board

In this user interface, you can set parameters for optical transponder boards. The parameters are laser status, automatic laser shutdown, maximum or minimum attenuation rate and path use status.

Parameters

Field	Value	Description
Optical Interface/Channel	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name) NOTE: For details about the differences between the standard and compatibility modes, see the Impacts of the Standard Mode on the U2000 Web LCT in Channel Model (OTU, Line or PID Board).
Optical Interface Name	For example: RX1/TX1	Indicates the default names. Do not modify this field.
Channel Use Status	Used, Unused	Specifies whether to use the path.
Optical Interface Loopback	Non-Loopback, Inloop, Outloop	Specifies loopback according to the port of the OTU board. Loopback may interrupt services and can be used only for testing or troubleshooting.
Service Type	For example: 10GE LAN	Specifies the service type of the client side.
OFC Enabled	Enabled, Disabled	Enables or disables the OFC function. This parameter can be edited only when you set Service Type to ISC 1G or ISC 2G.
Port Mapping	Bit Transparent Mapping (11.1G), MAC Transparent Mapping (10.7G), Bit Transparent Mapping (11.1G)	Indicates the flow control mode of the mapped trail of the service that passes the port.
Client Service Bearer Rate (M)	The transmission rate of the client-side service varies according to different OTU boards as follows: 100 to 2500 (applicable to the LDMS, LDMD, 12LDM, 12LQMS, 12LQMD, 13LQM, 12TQM, and TOM boards) 100 to 5000 (applicable to the 12LOM board) 16 to 2500 (applicable to other OTU boards)	Indicates the range of client service rates that the equipment can bear.
Laser Status	Open, Close	Specifies the status of a laser.
Automatic Laser Shutdown	Enabled, Disabled	Specifies whether to shut down the laser automatically. If auto-shutdown is set, when the received signal is lost, the laser shuts 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.
Service	For example: OTN	Selects the service mode of the port.
Board	The specific value is related to the board.	Sets the mode for the board. See Board Mode (WDM Interface) for more information.
LPT Enabled	Enabled, Disabled	Enables or disables the LPT pass-through function of the EPL service.
Current Bearer Rate (M)	For example: 50	Indicates the rate of the client service that is currently accessed.
FEC Working State	Enabled, Disabled	Specifies whether the board performs FEC processing on data.
FEC	FEC, AFEC, HFEC, SDFEC	Sets the FEC type. NOTE: If you modify the value of the FEC , the default value of the Degrade Threshold before FEC will be modified automatically.
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.
Actual Wavelength No./Wavelength (nm)/Frequency (THz)	For example: 1/1529.16/196.05	Indicates the actual working wavelength of the optical port. An actual wavelength is the optical wavelength emitted by a laser.
Actual Band Type	C, CWDM	Indicates the band of the actual working wavelength.
Configure Wavelength No./Wavelength (nm)/Frequency (THz)	For example: 1/1529.16/196.05	Indicates the configured wavelength, wavelength number, and frequency. This parameter is applicable to the NG WDM equipment. A configured wavelength is a logical wavelength. The function of setting configured wavelengths enables you to perform networking planning on the U2000 Web LCT instead of on the physical modules. When you use this function, manual mistakes will not lead to inconsistency between network deployment and network planning. End-to-end management of the U2000 Web LCT is implemented based on configured wavelengths instead of actual wavelengths of physical modules. The value of a configured wavelength is not changed or lost when relevant physical boards are changed or out of position. You need to set configured wavelengths during network planning. The functions of configured wavelengths are as follows: In the case of a tunable wavelength board, the corresponding NE automatically adjusts the wavelength of the board to an appropriate value according to the configured wavelength information of the corresponding logical slot. When you change a board, it is not necessary to manually adjust the wavelength. This automatic adjustment prevents manual mistakes. When an inappropriate fixed wavelength board is used, the corresponding NE detects that the wavelength of the current physical module is inconsistent with the configured wavelength. Thus, an alarm is generated. This greatly reduces the time for troubleshooting when services are interrupted due to an inappropriate wavelength. To keep consistency between the actual wavelength and configured wavelength, you can change the optical module of the board. NOTICE: Actual wavelengths must be consistent with the corresponding planned wavelengths. Otherwise, relevant services are interrupted and the networking planning is affected.
Configure Band Type	C, CWDM	Configures the band for the working wavelength.
Maximum Packet Length	1518-9600	Specifies the maximum packet length of the data. Packets that exceed this length are discarded.
Ethernet Working	Auto-Negotiation, 10M Half-Duplex, 10M Full-Duplex, 100M Half-Duplex, 100M Full-Duplex, 1000M Half-Duplex, 1000M Full-Duplex,	Indicates the working modes of the Ethernet port. 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.
OTN Overhead Transparent Transmission	Disabled, Enabled	Enables or disables the function of OTN Overhead Transparent Transmission.
SD Trigger Condition	B1_SD, OTUk_DEG, ODUk_PM_DEG	Specifies the SD switching condition.
FC Distance Extension	Enabled, Disabled	Enables or disables the FC distance extension.

NOTE:

In the case of different boards on different equipment, different WDM interfaces are supported. According to the corresponding user interface of the NMS, the parameter description table lists the whole set of parameters in this user interface of the NMS. For detailed parameters supported by each board, see the Hardware Description for each type of equipment.
