NE-Level Optical Cross-Connection

In this user interface, you can configure optical cross-connections on a single NE. An optical cross-connection refers to the cross-connection at the OCh level that can be dynamically created. An optical cross-connection can realize wavelength grooming. The optical cross-connection is classified into board-level optical cross-connection and NE-level optical cross-connection. A NE-level optical cross-connection refers to the end-to-end optical cross-connection within an NE.

Navigation Path

In the NE Explorer, click an NE and choose Configuration > Optical Cross-Connection Management from the Function Tree. Click the NE-Level Optical Cross-Connection tab.

Parameters

Field	Value	Description
Source Slot	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name Null	The Source Slot parameter indicates the slot number of the board where the source port of the cross-connection route of the NE-level optical cross-connection is located.
Source Port	Optical interface number, Null	The Source Port parameter indicates the source optical interface of the NE-Level optical cross-connect service.
Source Band	C, CWDM, Null	The Source Band parameter indicates the type of the band to which the source wavelength of the NE-level optical cross-connection belongs.
Source Wavelength No.	Wavelength No., Null, /	The Source Wavelength No. parameter indicates the number of the wavelength to which the source port of the NE-level optical cross-connection service corresponds.
Sink Slot	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name Null	The Sink Slot parameter indicates the slot number of the board where the sink port of the cross-connection route of the NE-level optical cross-connection is located.
Source Wavelength	Standard wavelength whose frequency bandwidth is 50 GHz, for example, C/5/195.850Thz Non-standard wavelength whose frequency bandwidth is 50 GHz, for example, C/195.76250Thz+-25GHz Frequency bandwidth 37.5 GHz: For example, C/195.64375Thz+-18.75GHz Frequency bandwidth 12.5GHz: For example, C/195.49375Thz+-6.25GHz User Define: N x 12.5 GHz, where N ranges from 1 to 32	Select a source wavelength in the GUI. shows that the frequency bandwidth is Standard 50GHz. You can click a wavelength number (for example, ) to select the wavelength whose center wavelength is standard and click the number again to cancel the selection. You can click any slice to select a wavelength whose frequency bandwidth is 50 GHz and click the slice again to cancel the selection. The gray slices indicate frequency bands that have been occupied. When the frequency bandwidth is 37.5GHz or 12.5GHz, you can click any slice to select a wavelength whose frequency bandwidth is 37.5 GHz or 12.5 GHz, and click the slice again to cancel the selection. For frequency spectrum with a small bandwidth (for example, 12.5 GHz), you can flexibly configure channel bandwidths to improve frequency spectrum utilization. When User Define is selected, you can enter an integer ranging from 1 to 32 and click any slice to select a wavelength whose frequency bandwidth is a multiple of 12.5 GHz.
Sink Port	Optical interface number, Null	The Sink Port parameter indicates the sink optical interface of the NE-level optical cross-connect service.
Sink Band	C, C(320G), CWDM, Null	The Sink Band parameter indicates the type of the band to which the sink wavelength of the NE-level optical cross-connection belongs.
Sink Wavelength No.	Wavelength No., Null, /	The Sink Wavelength No. parameter indicates the number of the wavelength to which the sink port of the NE-level optical cross-connect service corresponds.
Sink Wavelength	Standard wavelength whose frequency bandwidth is 50 GHz, for example, C/5/195.850Thz Non-standard wavelength whose frequency bandwidth is 50 GHz, for example, C/195.76250Thz+-25GHz Frequency bandwidth 37.5 GHz: For example, C/195.64375Thz+-18.75GHz Frequency bandwidth 12.5GHz: For example, C/195.49375Thz+-6.25GHz User Define: N x 12.5 GHz, where N ranges from 1 to 32	Select a sink wavelength in the GUI. shows that the frequency bandwidth is Standard 50GHz.

Service Origin	Create Manually, Intelligently Generate	Displays the mode of creating optical cross-connections.
OPA Mode	Auto, Manual Default: Auto	The OPA Mode parameter indicates the power adjustment mode of the NE-level optical cross-connect service. If the parameter is set to Auto, the equipment automatically adjust the attenuation of the optical attenuator in the dynamic optical add/drop multiplexing (OADM) board. If the parameter is set to Manual, manual adjustment in the attenuation of the optical attenuator in the dynamic OADM board is required. For the configuration principles of the auto mode, refer to Reference Information.
Create Reverse Cross-Connection	checked, unchecked	After you select Create Reverse Cross-Connection, you will create a forward optical cross-connection and a reverse optical cross-connection at the same time.
