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 U2000 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

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. The Auto option is available for the following types of optical cross-connection trails:
  • Pass-through service, such as OA > WSD9 > WSM9 > OA, OA > WSD9 > RMU9 > OA, and OA > ROAM > ROAM > OA.
  • Add service, such as OTU > WSM9 > OA, OTU > RMU9 > OA, and OTU > ROAM > OA.
  • Drop service, such as OA > WSD9 > OTU.
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:

The optical cross-connect services created are unidirectional. The reverse services need to be configured in addition. The configuration in the other direction is similar.

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

Only the operations to create optical cross-connection is described here. For the adjustment of the optical cross-connection, refer to the Commissioning Guide.

Procedure

  1. 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.
  2. Click Create. The Create NE-Level Optical Cross-Connection window is displayed.

    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 Available Wavelengths list. Click to add the wavelengths to Selected Wavelengths.
    • The optical cross-connection created in this procedure is unlike any of the three cases that are previously mentioned. Hence, you can only select MAN for Adjustment Mode.

  3. Click OK. The created NE-level optical cross-connection is displayed in the interface.
