Creating NE-Level Optical Cross-Connection

Optical cross-connection defines the routes of wavelengths. Through the creation of ne-level optical cross-connection, the routes of inter-board services are configured.

Prerequisites

The logic fiber connection inside a single station has been set up on the Web LCT.

The edge port must be configured.

When creating an optical cross-connection of a single station, make sure that the optical cross-connection of a board in this single station does not occupy the wavelength that the optical cross-connection of the single station uses.

Background Information

When you create an optical cross-connection, the optical power can be adjusted automatically or manually. If you select Auto, the dynamic optical add/drop multiplexing board automatically adjusts the attenuation range of the optical attenuator in the board. If you select Manual, you need to manually adjust the attenuation range of the optical attenuator in the dynamic optical add/drop multiplexing board.

NOTE:

The WSMD4 can be used to replace the WSD9 or the WSM9.

OA indicates the optical amplifier boards such as OAU1 and OBU1.

The FIU can be added before or after the OA.

In drop networking, the demultiplexer boards such as D40, D40V and MR2 can be added between the WSD9 and OTU.

In add networking, the multiplexer boards such as M40, M40V and MR2 can be added between the OTU and WSM9.

NOTE:

By default, only a forward optical cross-connection is created. You can select create reverse cross-connection to create a forward optical cross-connection and a reverse optical cross-connection at the same time.

Optical cross-connections are created by creating optical cross-connections on the board or on a single station. Creating optical cross-connections on a single station is recommended.

Procedure

Click the NE icon in the NE Explorer, and choose Configuration > Optical Cross-Connection Management from the Function Tree. Click NE-Level Optical Cross-Connection tab in the right-hand interface.
Click Create. The Create Optical Cross-Connection
NOTE:
- Select the source slot, sink slot, source port and sink port. Click the button on the right of Source Wavelength or Sink Wavelength. Select the wavelengths from the list. Click to add the wavelengths to .
- The optical cross-connection created in this procedure is unlike any of the three cases that are previously mentioned. Hence, you can only select for Power Adjustment Mode.
Optional: 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.
Click OK. The created ne-level optical cross-connection is displayed in the interface.
