Whether electrical cross-connections need to pass through when services are provisioned between OptiX OSN 6800 NEs and no signals are added to or dropped from the intermediate NE

10

In this scenario, electrical signals are not involved and therefore no electrical cross-connection needs to pass through.

Whether the NM_ETH port or the ETH port is used for communication between optical NEs and electrical NEs when optical NEs and electrical NEs are separated from each other
The NM_ETH port (the one connecting to the NMS) is used for communication between optical NEs and electrical NEs.

Whether fiber connections between NEs of OSN 6800 devices can be synchronized to the NMS
On the NMS, you can choose Fiber/Cable/Microwave Link > WDM Fiber/Cable Synchronization to synchronize the fiber connections between NEs of OSN 6800 devices.

Relationship between optical NEs and electrical NEs on an ASON network
When the optical and electrical NEs of an ASON NE are not split, the OTU or FIU boards on the ASON NE can function as edge points, and the related TE links can be automatically created when the boards are created. When the optical and electrical NEs are split, the multiplexer/demultiplexer or other optical-layer boards can function as the edge points of the optical NEs. When the fiber connections between the optical ports on the multiplexer/demultiplexer boards and those on the OTU boards are created, the intra-NE links that carry OCh signals are automatically created.

Precautions for configuring electrical cross-connections for different services on a tributary board of the OSN 6800
On the OSN 6800, electrical cross-connections of GE or Any services are between physical ports and logical ports on a tributary board. When configuring electrical cross-connections, set the level of GE service cross-connections to GE, and set the level of other service cross-connections to Any.
