Set port transceiver details

Perform the following steps for setting the SFP/CFP transceiver details on the port:

Go to Configuration > Layer 1 menu and click Manage L1 Ports option. Manage Ports page is displayed.
Do one of the following:
- Select Node check box and enter the IP address of the desired node in IP text box provided.
- Enter the name of the desired node in IP text box provided.
Click (Search Nodes). Shelf(s) and cards of the selected node are listed under Node Tree pane.
Click Ports drop-down under desired card and select OTU port under Node Tree pane.
Click TRANSCEIVER DETAILS tab. Port Transceiver Details pane is displayed with SFP details as shown in the following figure:

Port Transceiver Details pane is displayed with CFP details as shown in the following figure:
For SFP Port Transceiver Details, select the required frequency against the Laser Frequency (THz) parameter and select the ALS MODE from the drop down options. For CFP Port Transceiver Details, select the required frequency against the Laser Frequency (THz) parameter, select the ALS MODE from the drop down options and enter the TX Laser Output Power in the text box provided.
Click (Save Changes). Review Change Request window is displayed. Object field displays the OTU port parameters edited by the user with changed values under New Value field and previous values under Old Value field.
Do one of the following:
- To discard the unwanted changes, select the row against that change and click (Delete Changes). The selected row(s) will be crossed out and marked in red color. Go to next step.
- To commit all the changes, go to next step.
Click (Save Changes). Change Requests Status window is displayed listing the status of operation under Status field.
Click (Close) to exit Change Requests Status window. A message "Please refresh the Page or search Node. Automatically Refreshing the page in 3 minutes" is displayed.
Click OK. For the changes to apply and get updated in TJ5500, refreshing operation is required to be performed. This can be done in any of the two ways mentioned as follows:
- Manually by clicking on (Search Nodes) or refreshing the page; or
- Automatically, where a timer starts and the page will be refreshed in 3 minutes. The timer will be displayed on same page. If desired, user can click Stop link to stop the timer anytime but the refresh operation will be performed and changes will apply.
  (show changes saved) button allows you to view the saved changes in Recently saved changes window. This button is available only when the timer is visible.

SFP Port Transceiver parameters

Parameter	Description
Laser Frequency (THz)	Allows you to select the operating frequency of the laser in the transceiver.
Laser Wavelength (nm)	Displays the laser wavelength as per Laser Frequency value selected.
ALS MODE	Select the value based on the requirement. Disable: ALS is disabled. LOS will not cause laser shutdown. Automatic: Laser automatically turns on when ALS agent detects an LOS. If LOS still exists at that time, the laser is shut down again. This pattern continues until the LOS is cleared for 100 ms; then, the laser will stay on. Manual: A manual command can be issued that turns on the laser. Laser remains on only if there is no LOS on the transmitter.

Parameter

Description

Laser Frequency (THz)

Allows you to select the operating frequency of the laser in the transceiver.

Laser Wavelength (nm)

Displays the laser wavelength as per Laser Frequency value selected.

ALS MODE

Select the value based on the requirement.

Disable: ALS is disabled. LOS will not cause laser shutdown.
Automatic: Laser automatically turns on when ALS agent detects an LOS. If LOS still exists at that time, the laser is shut down again. This pattern continues until the LOS is cleared for 100 ms; then, the laser will stay on.
Manual: A manual command can be issued that turns on the laser. Laser remains on only if there is no LOS on the transmitter.

CFP Port Transceiver parameters

Parameter	Description
Tx Laser Frequency (THz)	Allows you to select the operating frequency of the laser at which the signal is transmitted.
Tx Laser Wavelength (nm)	Displays the laser wavelength as per Laser Frequency value selected at which the signal is transmitted.
Tx Laser Output Power (dBm)	Displays the power in terms of dBm at which the signal is transmitted.
ALS MODE	Select the value based on the requirement. Disable: ALS is disabled. LOS will not cause laser shutdown. Automatic: Laser automatically turns on when ALS agent detects an LOS. If LOS still exists at that time, the laser is shut down again. This pattern continues until the LOS is cleared for 100 ms; then, the laser will stay on. Manual: A manual command can be issued that turns on the laser. Laser remains on only if there is no LOS on the transmitter.
